In 1977, Executive Director Morris Levitt asserted that nuclear fusion power plants could be built by 1990 if the U.S. spent $50 to $100 billion on research. The same year he announced that there would be no United States in the 21st century if President Jimmy Carter's ban on building breeder reactors was maintained. The director of the fusion power program at Argonne National Laboratory, Charles Baker, said in 1983 that the FEF was "overstating" the prospect of practical fusion power in the near future. "The judgment of the vast majority of the people actually working in fusion believe it will take substantially longer" than the few years predicted by the FEF, according to Baker.
The beta of a plasma, symbolized by β, is the ratio of the plasma pressure (p = n kB T) to the magnetic pressure (pmag = B²/2μ0). The term is commonly used in studies of the Sun and Earth's magnetic field, and in the field of fusion power designs. In the fusion power field, plasma is often confined using strong magnets. Since the temperature of the fuel scales with pressure, reactors attempt to reach the highest pressures possible.
Target chamber of the Shiva laser, used for inertial confinement fusion experiments from 1978 until decommissioned in 1981. Plasma chamber of TFTR, used for magnetic confinement fusion experiments, which produced 11 MW of fusion power in 1994.

Hamlin was also a board member of Advanced Physics Corporation.
Large-scale reactors using neutronic fuels (e.g. ITER) and thermal power production (turbine based) are most comparable to fission power from an engineering and economics viewpoint. Both fission and fusion power stations involve a relatively compact heat source powering a conventional steam turbine-based power station, while producing enough neutron radiation to make activation of the station materials problematic. The main distinction is that fusion power produces no high-level radioactive waste (though activated station materials still need to be disposed of).
Controlled nuclear fusion could in principle be used in fusion power plants to produce power without the complexities of handling actinides, but significant scientific and technical obstacles remain. Several fusion reactors have been built, but only recently reactors have been able to release more energy than the amount of energy used in the process. Despite research having started in the 1950s, no commercial fusion reactor is expected before 2050. The ITER project is currently leading the effort to harness fusion power.
First plasma was obtained on NSTX on Friday, February 12, 1999 at 6:06 p.m. Magnetic fusion experiments use plasmas composed of one or more hydrogen isotopes. For example, in 1994, PPPL's Tokamak Fusion Test Reactor (TFTR) produced a world-record 10.7 megawatts of fusion power from a plasma composed of equal parts of deuterium and tritium, a fuel mix likely to be used in commercial fusion power reactors. NSTX was a "proof of principle" experiment and therefore employed deuterium plasmas only.
That is, fission reactors that produce more fissile fuel than they consume - breeder reactors, and when it is developed, fusion power, are both classified within the same category as conventional renewable energy sources, such as solar and falling water. Presently, as of 2014, only 2 breeder reactors are producing industrial quantities of electricity, the BN-600 and BN-800. The retired French Phénix reactor also demonstrated a greater than one breeding ratio and operated for ~30 years, producing power when Our Common Future was published in 1987. While human sustained nuclear fusion is intended to be proven in the International thermonuclear experimental reactor between 2020 and 2030, and there are also efforts to create a pulsed fusion power reactor based on the inertial confinement principle (see more Inertial fusion power plant).
The size of the investments and time frame of the expected results mean that until recently fusion research has almost exclusively been publicly funded. However, in the last few years, a number of start-up companies active in the field of fusion power have attracted over 1.5 billion dollars, with investors including Jeff Bezos, Peter Thiel and Bill Gates, as well as institutional investors including Legal & General, and most recently energy companies like Equinor, Eni, Chevron, and the Chinese ENN Group. In September 2019, Bloomberg found that over twenty private companies are working on fusion power, as is a US- based Fusion Industry Association.

Gillette has also produced powered variants of the Mach3 (M3Power, M3Power Nitro) and Fusion (Fusion Power and Fusion Power Phantom) razors. These razors accept a single AAA battery which is used to produce vibration in the razor; this action was purported to raise hair up and away from the skin prior to being cut. These claims were ruled in an American court as "unsubstantiated and inaccurate".
The second phase would include an update of the system to obtain fusion power production of 1 GW or 1000 MW (compared to ITER's 500 MW) and a fusion gain higher than 12, with tritium self-sufficiency.
A still more useful figure of merit is the "triple product" of density, temperature, and confinement time, nTτE. For most confinement concepts, whether inertial, mirror, or toroidal confinement, the density and temperature can be varied over a fairly wide range, but the maximum attainable pressure p is a constant. When such is the case, the fusion power density is proportional to p2<σv>/T 2. The maximum fusion power available from a given machine is therefore reached at the temperature T where <σv>/T 2 is a maximum.

This shows a basic magnetic mirror machine including a charged particle's motion. The rings in the centre extend the confinement area horizontally, but are not strictly needed and are not found on many mirror machines. A magnetic mirror, known as a magnetic trap (магнитный захват) in Russia and briefly as a pyrotron in the US, is a type of magnetic confinement device used in fusion power to trap high temperature plasma using magnetic fields. The mirror was one of the earliest major approaches to fusion power, along with the stellarator and z-pinch machines.

This fusion experimental devices has capability to capture the low neutron flux on the order of 105 to 108 neutrons per cm2 per second, resulting in nucleosynthesis by the s-process (slow-neutron-capture-process).
Fusion power would provide more energy for a given weight of fuel than any fuel-consuming energy source currently in use, and the fuel itself (primarily deuterium) exists abundantly in the Earth's ocean: about 1 in 6500 hydrogen atoms in seawater is deuterium. Although this may seem a low proportion (about 0.015%), because nuclear fusion reactions are much more energetic than chemical combustion, and seawater is easier to access and more plentiful than fossil fuels, fusion could potentially supply the world's energy needs for millions of years. Fusion power could be used in interstellar space where solar energy is not available.
An inertial fusion power plant is intended to produce electric power by use of inertial confinement fusion techniques on an industrial scale. This type of power plant is still in a research phase. Two established options for possible medium-term implementation of fusion energy production are magnetic confinement, being used in the ITER international project, and laser-based inertial confinement, as used in the French Laser Mégajoule and in the American NIF. Inertial confinement fusion (ICF), including heavy-ion inertial fusion (HIF), has been proposed as a possible additional means of implementing a fusion power plant.
To achieve a near tenfold increase in fusion power density, the design makes use of rare-earth barium-copper-oxide (REBCO) superconducting tape for its toroidal field coils. The intense magnetic field allows sufficient confinement of superhot plasma in such a small device. In theory, the achievable fusion power density of a reactor is proportional to the fourth power of the magnetic field intensity. The most probable candidate in this class of materials is Yttrium barium copper oxide, with a design temperature of suitable for the liquid nitrogen refrigeration instead of the much more complex liquid helium refrigeration required by ITER magnets.

The deuterium-tritium fusion reaction generates mono-energetic neutrons with an energy of 14.1 MeV. In fusion power plants, neutrons will be present at fluxes in the order of 1018 m−2s−1 and will interact with the material structures of the reactor by which their spectrum will be broadened and softened. A fusion relevant neutron source is an indispensable step towards the successful development of fusion energy. Safe design, construction and licensing of a fusion power facility by the corresponding Nuclear Regulatory agency will require data on the plasma- facing materials degradation under neutron irradiation during the life-time of a fusion reactor.
However, since the early 1970s its areas of work have been gradually reduced, with functions transferred to other government organisations as well as to the private sector. The authority now focuses on United Kingdom and European fusion power research programmes at Culham in Oxfordshire, including the world's most powerful fusion device, the Joint European Torus. The research aims to develop fusion power as a commercially viable, environmentally sound energy source for the future. United Kingdom Atomic Energy Authority owns the Culham Science Centre and has a stake in the Harwell Campus, and is involved in the development of both sites as locations for science and innovation-based business.
A flux loop is a loop of wire placed inside a plasma at a right angle. Changes in the field create a current in the loop, which may be interpreted to measure the properties of the plasma. Flux loops are key diagnostics in fusion power research.
If it is developed, Fusion power would provide more energy for a given weight of fuel than any fuel-consuming energy source currently in use, and the fuel itself (primarily deuterium) exists abundantly in the Earth's ocean: about 1 in 6500 hydrogen (H) atoms in seawater (H2O) is deuterium in the form of (semi-heavy water). Although this may seem a low proportion (about 0.015%), because nuclear fusion reactions are so much more energetic than chemical combustion and seawater is easier to access and more plentiful than fossil fuels, fusion could potentially supply the world's energy needs for millions of years. In the deuterium + lithium fusion fuel cycle, 60 million years is the estimated supply lifespan of this fusion power, if it is possible to extract all the lithium from seawater, assuming current (2004) world energy consumption. While in the second easiest fusion power fuel cycle, the deuterium + deuterium burn, assuming all of the deuterium in seawater was extracted and used, there is an estimated 150 billion years of fuel, with this again, assuming current (2004) world energy consumption.
The fuel ionizes and is accelerated towards the inner cage. If the ions miss the inner cage, they can fuse together. Fusors are not considered part of the CBFR family, because they do not traditionally use beams. There are numerous problems with the fusor as a fusion power reactor.
Its purpose is to advance stellarator technology, though this experimental reactor will not produce electricity, it is used to evaluate the main components of a future fusion power plant; it was developed based on the predecessor Wendelstein 7-AS experimental reactor. , the Wendelstein 7-X reactor is the largest stellarator device. It has been anticipated to achieve operations of up to approximately 30 minutes of continuous plasma discharge in 2021, thus demonstrating an essential feature of a future fusion power plant: continuous operation. The name of the project, referring to the mountain Wendelstein in Bavaria, was decided at the end of the 1950s, referencing the preceding project from Princeton University under the name Project Matterhorn.
Project PACER, carried out at Los Alamos National Laboratory (LANL) in the mid-1970s, explored the possibility of a fusion power system that would involve exploding small hydrogen bombs (fusion bombs)—or, as stated in a later proposal, fission bombs—inside an underground cavity. As an energy source, the system is the only fusion power system that could be demonstrated to work using existing technology. It would also require a continuous supply of nuclear bombs and contemporary economics studies demonstrated that these could not be produced at a competitive price compared to conventional energy sources. The earliest references to the use of nuclear explosions for power generation date to a meeting called by Edward Teller in 1957.

The cross-sections of different fusion reactions Nuclear fusion refers to reactions in which lighter nuclei are combined to become heavier nuclei. This process changes mass into energy which in turn may be captured to provide fusion power. Many types of atoms can be fused. The easiest to fuse are deuterium and tritium.
Nuclear fusion power is a developing technology still under research. It relies on fusing rather than fissioning (splitting) atomic nuclei, using very different processes compared to current nuclear power plants. Nuclear fusion reactions have the potential to be safer and generate less radioactive waste than fission.Introduction to Fusion Energy, J. Reece Roth, 1986.

He also stated that the density would scale with the square of the field (constant beta conditions), and the maximum attainable magnetic field would scale with the radius. Under those conditions, the fusion power produced would scale with the seventh power of the radius, and the energy gain would scale with the fifth power. While Bussard did not publicly document the reasoning underlying this estimate, Possibly he assumed that the ion energy distribution is fixed, that the magnetic field scales with the linear size, and that the ion pressure (proportional to density) scales with the magnetic pressure (proportional to B²). The R7 scaling results from multiplying the fusion power density (proportional to density squared, or B4) with the volume (proportional toR³).

The China Fusion Engineering Test Reactor (CFETR) is a proposed tokamak nuclear fusion reactor in China. CFETR construction is planned for the 2020s as a demonstration of the feasibility of large scale fusion power generation. The project would include two phases of operation. The first phase aims to demonstrate steady-state operation and tritium breeding.
Its planned successor, DEMO—which for some ITER consortium countries may now be a phase rather than a specific ITER consortium machine—is expected to be the first fusion reactor to produce electricity in an experimental environment. The DEMO phase is expected to lead to full-scale electricity-producing fusion power stations and future commercial reactors.
Not all authors think the extraterrestrial extraction of helium-3 is feasible, and even if it was possible to extract helium-3 from the Moon, no fusion reactor design has produced more fusion power output than the electrical power input, defeating the purpose. Another downside is that it is a limited resource that can be exhausted once mined.
A similar joke has been used about the feasibility of fusion power: Since the 1950s, feasible technological means of using hot fusion for electricity production have constantly been predicted as being 30–40 years ahead, so the "fusion constant" exhibits a similar range to the "oil constant".Ulf von Rauchhaupt, "Sonnenfeuer am Boden", Die Zeit, 15 April 1999.
The Tandem Mirror Experiment (TMX and TMX-U) was a magnetic mirror machine operated from 1979 to 1987 at the Lawrence Livermore National Laboratory. The machine trapped ions and electrons between two magnetic mirrors. Ions would bounce back and forth in a line, collide in the center and fuse. This was an early experiment towards fusion power.
The outer layer of the pellet is ablated, providing a reaction force that compresses the central 10% of the fuel by a factor of 10 or 20 to 103 or times solid density. These microplasmas disperse in a time measured in nanoseconds. For a fusion power reactor, a repetition rate of several per second will be needed.
Nuclear power can be obtained from nuclear fission, nuclear decay and nuclear fusion reactions. Presently, the vast majority of electricity from nuclear power is produced by nuclear fission of uranium and plutonium. Nuclear decay processes are used in niche applications such as radioisotope thermoelectric generators. Generating electricity from fusion power remains at the focus of international research.
Toki is increasing a bedroom community for nearby Gifu and Nagoya. The city is known for its production of ceramics. In Spring 2005, a number of large outlet malls was opened on the outskirts of the city. The city is home to the Large Helical Device, a stellarator investigating plasma physics with an eye towards fusion power generation.
It is hypothesized that one of Neptune's satellites could be used for colonization. Triton's surface shows signs of extensive geological activity that implies a subsurface ocean, perhaps composed of ammonia/water. If technology advanced to the point that tapping such geothermal energy was possible, it could make colonizing a cryogenic world like Triton feasible, supplemented by nuclear fusion power.
The Sandia Laboratories Z-IFE project aims to solve the practical difficulties in harnessing fusion power. Major problems include producing energy in a single Z-pinch shot, and quickly reloading the reactor after each shot. By their early estimates, an implosion of a fuel capsule every 10 seconds could economically produce 300 MW of fusion energy.
The Tokamak Fusion Test Reactor (TFTR) was an experimental tokamak built at Princeton Plasma Physics Laboratory (PPPL) circa 1980 and entering service in 1982. TFTR was designed with the explicit goal of reaching scientific breakeven, the point where the heat being released from the fusion reactions in the plasma is equal or greater than the heating being supplied to the plasma by external devices to warm it up. The TFTR never achieved this goal, but it did produce major advances in confinement time and energy density. It was the world's first magnetic fusion device to perform extensive scientific experiments with plasmas composed of 50/50 deuterium/tritium (D-T), the fuel mix required for practical fusion power production, and also the first to produce more than 10 MW of fusion power.
In 1983, as assistant director for the MIT Plasma Fusion Center, Lidsky wrote an influential article about the difficulties of making a working nuclear fusion power plant.. The ensuing reduction in federal funding for fusion research led him to resign from the center, and caused him to be "drummed out" of the nuclear fusion research community.. Because of his concerns with the viability of fusion power, he instead became by 1989 an advocate for safer nuclear fission reactor designs.. In 1999 he was named a fellow of the American Association for the Advancement of Science "for outstanding contributions to both nuclear fission and fusion in education, research, system design and analysis, technical publications and federal policy".. He died March 1, 2002 in Newton, Massachusetts, after struggling with cancer for many years...
While fusion power is still in early stages of development, substantial sums have been and continue to be invested in research. In the EU almost was spent on fusion research up to the end of the 1990s, and the ITER reactor alone represents an investment of over twenty billion dollars, and possibly tens of billions more including in-kind contributions. In 2002, it was estimated that up to the point of possible implementation of electricity generation by nuclear fusion, R&D; would need further promotion totalling around over a period of or so (of which from within the EU). Under the European Union's Sixth Framework Programme, nuclear fusion research received (in addition to ITER funding), compared with for sustainable energy research, putting research into fusion power well ahead of that of any single rivaling technology.
The next step planned would be the Z-IFE (Z-inertial fusion energy) test facility, the first true z-pinch driven prototype fusion power plant. It is suggested it would integrate Sandia's latest designs using LTDs. Sandia labs recently proposed a conceptual 1 petawatt (1015 watts) LTD Z-pinch power plant, where the electric discharge would reach 70 million amperes.W.A. Stygar et al.
The Perhapsatron was an early fusion power device based on the pinch concept in the 1950s. Conceived by James (Jim) Tuck while working at Los Alamos National Laboratory (LANL), he whimsically named the device on the chance that it might be able to create fusion reactions.Brown, Laurie M.; Pais, Abraham; and Pippard, A. B. "Twentieth century physics", p. 1636, CRC Press, .
United Kingdom Atomic Energy Authority states its mission as "to lead the commercial development of fusion power and related technology and position the United Kingdom as a leader in sustainable nuclear energy." Its research programmes include a number of laboratories and other facilities at the Culham site. A plasma test in the MAST experiment at Culham Centre for Fusion Energy, 2013.
The two main forms of transportation are the riverboat and the zeppelin. The riverboat Not-for-Hire was built by Samuel Clemens, while the zeppelin was built by the man who built the Hindenburg and is called Herumfurzeln (which means in German to fart around). Both use what is suspected by one of the characters to be a fusion power source.
In 1979, Eastlund left Fusion Systems to become Vice President of Energy Research for BDM Corporation. Eastlund served as a member of the Board of Directors and also as treasurer at Fusion Power Associates. After leaving BDM, Eastlund worked for Atlantic Richfield Corporation. In 1987 he founded Production Technologies International Corporation and in 1996 he founded Eastlund Scientific Enterprises Corporation.
MTF is not the first "new approach" to fusion power. When ICF was introduced in the 1960s, it was a radical new approach that was expected to produce practical fusion devices by the 1980s. Other approaches have encountered unexpected problems that greatly increased the difficulty of producing output power. With MCF, it was unexpected instabilities in plasmas as density or temperature was increased.
The nuclei do not actually have to have enough energy to overcome the Coulomb barrier completely. If they have nearly enough energy, they can tunnel through the remaining barrier. For these reasons fuel at lower temperatures will still undergo fusion events, at a lower rate. Thermonuclear fusion is one of the methods being researched in the attempts to produce fusion power.
In 1968, Ohkawa became a Fellow of the American Physical Society. In 1979, he received the James Clerk Maxwell Prize for Plasma Physics for "his development of multi-current or doublet approach to the design of tokamaks with non- circular cross sections and for investigation of plasma confinement in toroidal multipoles". He also received the 1984 Fusion Power Associates Leadership Award.
Although Nova failed in this goal, the data it generated clearly defined the problem as being mostly a result of Rayleigh–Taylor instability, leading to the design of the National Ignition Facility, Nova's successor. Nova also generated considerable amounts of data on high-density matter physics, regardless of the lack of ignition, which is useful both in fusion power and nuclear weapons research.
SPARC is a tokamak that has been proposed for construction by Commonwealth Fusion Systems (CFS) in collaboration with the Massachusetts Institute of Technology (MIT) Plasma Science and Fusion Center (PSFC), with funding from Eni, Breakthrough Energy Ventures, Khosla Ventures, Temasek, Equinor, Devonshire Investors, and others. SPARC plans to prove out the technology and physics required to build a power plant based on the ARC fusion power plant concept. SPARC proposes to use powerful magnets built with new yttrium barium copper oxide (YBCO) high temperature superconductor in order to produce plasmas that generate twice as much energy as is required to sustain them at high temperatures, giving a fusion gain Q > 2. SPARC is designed to meet this mission with margin and may be capable of achieving up to 140 MW of fusion power for 10 second bursts despite being a relatively compact device.
Fusion Energy Foundation (FEF) was an American non-profit think tank co- founded by Lyndon LaRouche in 1974 in New York. It promoted the construction of nuclear power plants, research into fusion power and beam weapons and other causes. The FEF was called fusion's greatest private supporter. It was praised by scientists like John Clarke, who said that the fusion community owed it a "debt of gratitude".
Spider-Man puts out the flames, while defeating all the crooks. Harry introduces Peter to Dr. Otto Octavius, a nuclear scientist who is trying to make a fusion power experiment, sponsored by Oscorp, which would provide an unlimited source power to Manhattan. Octavius befriends and begins to mentor Peter. While handling hazardous materials, Octavius wears a harness of powerful robotic tentacle arms with artificial intelligence.
ITER will produce energy by fusing deuterium and tritium to helium. Fusion power has the potential to provide sufficient energy to satisfy mounting demand, and to do so sustainably, with a relatively small impact on the environment. 1 gram of deuterium-tritium mixture in the process of nuclear fusion produces an amount of energy equivalent to burning 8 tonnes of oil. Nuclear fusion has many potential attractions.
In addition, there are approximately 140 naval vessels using nuclear propulsion in operation, powered by some 180 reactors. Naval Nuclear Propulsion, Magdi Ragheb. As of 2001, about 235 naval reactors had been built As of 2013, attaining a net energy gain from sustained nuclear fusion reactions, excluding natural fusion power sources such as the Sun, remains an ongoing area of international physics and engineering research.
Cluster Impact Fusion is a suggested method of producing practical fusion power using small clusters of heavy water molecules directly accelerated into a titanium-deuteride target. Calculations suggested that such a system enhanced the cross section by many orders of magnitude. It is a particular implementation of the larger beam-target fusion concept. The idea was first reported by researchers at Brookhaven in 1989.
Lower hybrid waves are launched preferentially in the direction opposite the plasma current (i.e. in the direction of electron travel) and deposit energy on electrons moving at approximately three times the thermal velocity via Landau damping. A major area of LHCD research has been in the area of current drive at the high densities (ne > 1020 m−3) required for a fusion power plant.
Although confinement schemes can be and sometimes are limited by other factors, most well-investigated schemes have some kind of pressure limit. Under these assumptions, the power density for p–11B is about 2,100 times smaller than that for D-T. Using cold electrons lowers the ratio to about 700. These numbers are another indication that aneutronic fusion power is not possible with mainline confinement concepts.
Staff (1996) "Fusion Lab Planning Big Reactor's Last Run" The Record, 22 December 1996, p. N-07 Beginning in 1993, TFTR was the first in the world to use 50/50 mixtures of deuterium-tritium. In 1994 it yielded an unprecedented 10.7 megawatts of fusion power. In 1999, the National Spherical Torus Experiment (NSTX), based on the spherical tokamak concept, came online at the PPPL.
Robin Herman. 1990. These demonstrated that the system could reach the goals of the initial 1976 design; the performance when running on deuterium was such that if tritium was introduced it was expected to produce about 3.5 MW of fusion power. Given the energy in the heating systems, this represented a Q of about 0.2, or about only 20% of the requirement for break- even. Further testing revealed significant problems, however.
The £220 million STEP programme aims to accelerate the delivery of fusion power to the energy market. STEP will be a prototype reactor capable of demonstrating fusion as a viable technology for electricity generation. It uses the compact 'spherical tokamak' concept developed by UKAEA at Culham Centre for Fusion Energy. STEP is currently in a five-year conceptual design phase and is expected to be constructed and operational by 2040.
On the other hand, if it is important to maintain the ratio of the Debye length or the gyroradius to the machine size, then the magnetic field strength would have to scale inversely with the radius, so that the total power output would actually be lower in a larger machine. if true, it would enable a model only ten times larger to be useful as a fusion power plant.

A divertor is part of the tokamak that is designed to exhaust the excess heat and impurities from the plasma. Conventional divertor designs, when scaled up to future powerplants, will experience very high heat loads and will need to be replaced every few years. The Super-X divertor should demonstrate much lower heat loads (by around a factor of 10), potentially solving one of the major challenges of commercially viable fusion power in the future.

A "Remote Handling" system is, in general, an essential tool for any subsequent fusion power plant and especially for the International Thermonuclear Experimental Reactor (ITER) being developed at Saint-Paul-lès-Durance, in Provence, southern France. This Remote Handling system was later to lead on to become RACE (Remote Applications in Challenging Environments). In 1999, the European Fusion Development Agreement (EFDA) was established with responsibility for the future collective use of JET.

TAE Technologies (formerly Tri Alpha Energy) is an American company based in Foothill Ranch, California, created for the development of aneutronic fusion power. The company's design relies on a field-reversed configuration (FRC), which combines features from other fusion concepts in a unique fashion. The company was founded in 1998, and is backed by private capital. They operated as a stealth company for many years, refraining from launching its website until 2015.
The next year, energy corporation Eni announced a $50 million investment in the newly founded Commonwealth Fusion Systems, to attempt to commercialize ARC technology using a test reactor (SPARC) in collaboration with MIT. In terms of national fusion power plants, in 2019 the United Kingdom announced a planned £200-million (US$248-million) investment to produce a design for a fusion facility named the Spherical Tokamak for Energy Production (STEP), by the early 2040s.
According to most anti-nuclear groups, nuclear fusion power "remains a distant dream". The World Nuclear Association have said that fusion "presents so far insurmountable scientific and engineering challenges". Construction of the ITER facility began in 2007, but the project has run into many delays and budget overruns. Several milestones of the project has already been finished, but the finishing date for First Plasma has been discussed and postponed many times with various conclusions.

HSX stellarator A stellarator is a plasma device that relies primarily on external magnets to confine a plasma. In the future, scientists researching magnetic confinement fusion aim to use stellarator devices as a vessel for nuclear fusion reactions. The name refers to the possibility of harnessing the power source of the stars, including the sun. It is one of the earliest fusion power devices, along with the z-pinch and magnetic mirror.
One of the most significant experiments to occur at AERE was the ZETA fusion power experiment. An early attempt to build a large-scale nuclear fusion reactor, the project was started in 1954, and the first successes were achieved in 1957. In 1968 the project was shut down, as it was believed that no further progress could be made with the kind of design that ZETA represented (see Timeline of nuclear fusion).
HiPER requires about 270 kJ of laser energy, so assuming a first- generation diode laser driver at 10% the reactor would require about 3 MJ of electrical power. This is expected to produce about 30 MJ of fusion power. Even a very poor conversion to electrical energy appears to offer real-world power output, and incremental improvements in yield and laser efficiency appear to be able to offer a commercially useful output.
Alternatives for energy production through fusion of hydrogen has been under investigation since the 1950s. No materials can withstand the temperatures required to ignite the fuel, so it must be confined by methods which use no materials. Magnetic and inertial confinement are the main alternatives (Cadarache, Inertial confinement fusion) both of which are hot research topics in the early years of the 21st century. Fusion power is the process driving the sun and other stars.
The main campuses of Simon Fraser University and the British Columbia Institute of Technology are located in Burnaby. It is home to high- tech companies such as Ballard Power (fuel cell), Clio (legal software), D-Wave (quantum computing), General Fusion (fusion power), Electronic Arts Vancouver, and Capcom Canada. Burnaby's Metropolis at Metrotown is the largest mall in British Columbia, and second largest in Canada. The city is served by the Expo Line and the Millennium Line.
Supporters of ITER emphasize that the only way to test ideas for withstanding the intense neutron flux is to experimentally subject materials to that flux, which is one of the primary missions of ITER and the IFMIF, and both facilities will be vitally important to that effort.Nuclear Data for Helium Production in Fusion. (PDF). Retrieved 21 May 2013. The purpose of ITER is to explore the scientific and engineering questions that surround potential fusion power stations.
Made redundant in 1961, he joined General Atomic and worked on the Orion space propulsion system, which proposed using a controlled sequence of nuclear explosions to propel the spacecraft. He also worked on atomic-powered gas turbines.Colin F. McDonald, John C. Bass & Hans H. Amtmann; Primary System Design Studies for Advanced Direct Cycle Nuclear Gas Turbine Plant, AMSE, 1977. He moved to a small company working on nuclear fusion power in 1980, until the company closed in 1984.
These reactions appear potentially viable, though technically quite difficult and have yet to be created on a scale that could be used in a functional power plant. Fusion power has been under theoretical and experimental investigation since the 1950s. Construction of the International Thermonuclear Experimental Reactor facility began in 2007, but the project has run into many delays and budget overruns. The facility is now not expected to begin operations until the year 2027 – 11 years after initially anticipated.
However, with the upswing in research in the general area of fusion reactor technology (ITER, DEMO) there has been renewed interest during the last decade in better processes for 6Li-7Li separation, especially in Japan and the US. North Korea is assessed to have procured the wherewithal to build a lithium-6 enrichment plant based on the COLEX separation. No industrial-scale facilities exist today that could meet the future requirements of commercial fusion power plants.
The only reason Earth's environment does not decay into an equilibrium state is that it receives a daily dose of sunshine and that, in turn, is due to the sun "polluting" interstellar space with decreasing entropy. The sun's fusion power is only possible due to the gravitational disequilibrium of matter that arose from cosmic expansion. In this essence, the vacuum energy can be viewed as the key cause of the negative entropy (i.e. structure) throughout the universe.
This work was done at the NOVA laser system, General Atomics, Laser Mégajoule and the GEKKO XII system in Japan. Through this work and lobbying by groups like the fusion power associates and John Sethian at NRL, a vote was made in congress, authorizing funding for the NIF project in the late nineties. In the early nineties, theory and experimental work regarding fusors and polywells was published."Inertial electrostatic fusion (IEF): A clean energy future" (Microsoft Word document).
Scenarios has been presented of the effect of the commercialization of fusion power on the future of human civilization. ITER and later DEMO are envisioned to bring online the first commercial nuclear fusion energy reactor by 2050. Using this as the starting point and the history of the uptake of nuclear fission reactors as a guide, the scenario depicts a rapid take up of nuclear fusion energy starting after the middle of this century.As such, regulator issues have arisen.

Many spacecraft propulsion methods such as ion thrusters require an input of electric power to run but are highly efficient. In some cases their maximum thrust is limited by the amount of power that can be generated (for example, a mass driver). An electric generator that ran on fusion power could be installed purely to drive such a ship. One disadvantage is that conventional electricity production requires a low-temperature energy sink, which is difficult (i.e.
In conceptualized (hypothetical) nuclear fusion power plants, lithium will be used to produce tritium in magnetically confined reactors using deuterium and tritium as the fuel. Naturally occurring tritium is extremely rare, and must be synthetically produced by surrounding the reacting plasma with a 'blanket' containing lithium where neutrons from the deuterium-tritium reaction in the plasma will fission the lithium to produce more tritium: :6Li + n → 4He + 3H. Lithium is also used as a source for alpha particles, or helium nuclei.
Two years after the Green Goblin's death, Peter's friend Harry Osborn introduces him to Dr. Otto Octavius, a nuclear scientist who is trying to make a fusion power experiment, sponsored by Oscorp, which would provide an unlimited source power to Manhattan. Octavius befriends and begins to mentor Peter. While handling hazardous materials, Octavius wears a harness of powerful robotic tentacle arms with artificial intelligence. During a public demonstration that Peter and Harry attend, a power spike causes the fusion reactor to destabilize.
Contributing to this trend is the fact that PhD programmes in Iran now require students to have publications in the Web of Science. Iran has submitted a formal request to participate in a project which is building an International Thermonuclear Experimental Reactor (ITER) in France by 2018. This megaproject is developing nuclear fusion technology to lay the groundwork for tomorrow's nuclear fusion power plants. The project involves the European Union, China, India, Japan, Republic of Korea, Russian Federation and USA.

MSR interest resumed in the new millennium with continuing delays in fusion power and other nuclear power programs. The LFTR design was strongly supported by Alvin Weinberg, who patented the light-water reactor and was a director of the U.S.'s Oak Ridge National Laboratory. In 2016 Nobel prize winning physicist Carlo Rubbia, former Director General of CERN, claimed that one of the main reasons why research was cut is that thorium is difficult to turn into a nuclear weapon.

He worked on integrating situation awareness and command and control technology onto the USS John F. Kennedy (CV-67). From 1978 to 1983, he was a consultant, visiting researcher and graduate student intern at Pacific Northwest National Laboratory, Exxon Research and TRW. From 1980 to 1984, McGrath was a visiting summer research scientist, specializing in fusion power, at Argonne National Laboratory.
This is core degradation. Nevins argued mathematically, that the fusion gain (ratio of fusion power produced to the power required to maintain the non-equilibrium ion distribution function) is limited to 0.1 assuming that the device is fueled with a mixture of deuterium and tritium. The core focus problem was also identified in fusors by Tim Thorson at the University of Wisconsin–Madison during his 1996 doctoral work. Charged ions would have some motion before they started accelerating in the center.
A diagram depicting the poloidal (\theta) direction, represented by the red arrow, and the toroidal (\zeta or \phi) direction, represented by the blue arrow. The major axis, R, is measured from the center of the hole in the middle to the center of the cylindrical confinement area. The minor axis, r, is the radius of the cylinder. In a toroidal fusion power reactor, the magnetic fields confining the plasma are formed in a helical shape, winding around the interior of the reactor.
F4E also aims to contribute to DEMO (Demonstration Power Plant). This experiment is supposed to generate significant amounts of electricity over extended periods and will be self- sufficient in tritium, one of the necessary gases to create fusion. The first commercial fusion electricity power plants are set to be established following DEMO, which is set to be larger in size than ITER and to produce significantly larger fusion power over long periods: a continuous production of up to 500 megawatts of electricity.
The Joint European Torus (JET) magnetic fusion experiment in 1991 Fusion power is a proposed form of power generation that would generate electricity by using heat from nuclear fusion reactions. In a fusion process, two lighter atomic nuclei combine to form a heavier nucleus, while releasing energy. Devices designed to harness this energy are known as fusion reactors. Fusion processes require fuel and a confined environment with sufficient temperature, pressure, and confinement time to create a plasma in which fusion can occur.
As a source of power, nuclear fusion is expected to have many advantages over fission. These include reduced radioactivity in operation and little high- level nuclear waste, ample fuel supplies, and increased safety. However, the necessary combination of temperature, pressure, and duration has proven to be difficult to produce in a practical and economical manner. Research into fusion reactors began in the 1940s, but to date, no design has produced more fusion power output than the electrical power input, defeating the purpose.
Controlled, viable fusion power has proven elusive, despite the occasional hoax. Technical and theoretical difficulties have hindered the development of working civilian fusion technology, though research continues to this day around the world. Nuclear fusion was initially pursued only in theoretical stages during World War II, when scientists on the Manhattan Project (led by Edward Teller) investigated it as a method to build a bomb. The project abandoned fusion after concluding that it would require a fission reaction to detonate.
Hot plasma, magnetically confined in a tokamak Magnetic confinement fusion is an approach to generate thermonuclear fusion power that uses magnetic fields to confine fusion fuel in the form of a plasma. Magnetic confinement is one of two major branches of fusion energy research, along with inertial confinement fusion. The magnetic approach began in the 1940s and absorbed the majority of subsequent development. Fusion reactions combine light atomic nuclei such as hydrogen to form heavier ones such as helium, producing energy.

Instead, these machines demonstrated new problems that limited their performance. Solving these would require a much larger and more expensive machine, beyond the abilities of any one country. After an initial agreement between Ronald Reagan and Mikhail Gorbachev in November 1985, the International Thermonuclear Experimental Reactor (ITER) effort emerged and remains the primary international effort to develop practical fusion power. Many smaller designs, and offshoots like the spherical tokamak, continue to be used to investigate performance parameters and other issues.

Ronald Richter working during the Huemul Project. The Huemul Project () was an early 1950s Argentine effort to develop a fusion power device known as the Thermotron. The concept was invented by Austrian scientist Ronald Richter, who claimed to have a design that would produce effectively unlimited power. Richter was able to pitch the idea to President Juan Perón in 1948, and soon received funding to build an experimental site on Huemul Island, just outside the town of San Carlos de Bariloche in Patagonia, near the Andes mountains.
Proponents note that large-scale fusion power would be able to produce reliable electricity on demand, and with virtually zero pollution (no gaseous CO2, SO2, or NOx by-products are produced). According to researchers at a demonstration reactor in Japan, a fusion generator should be feasible in the 2030s and no later than the 2050s. Japan is pursuing its own research program with several operational facilities that are exploring several fusion paths. In the United States alone, electricity accounts for US$210 billion in annual sales.
In a toroidal fusion power device, a plasma is confined within a donut-shaped cylinder. If the gas pressure of the plasma varies across the radius of the cylinder, a self-generated current will spontaneously arise within the plasma, due to collisions between trapped particles and passing particles. This current is called the bootstrap current, and is commonly found in tokamak fusion devices. The tokamak uses a combination of external magnets and a current driven in the plasma to create a stable confinement system.
The United Kingdom Atomic Energy Authority is a UK government research organisation responsible for the development of nuclear fusion power. It is an executive non-departmental public body of the Department for Business, Energy and Industrial Strategy (BEIS). On its formation in 1954, the authority was responsible for the United Kingdom's entire nuclear programme, both civil and defence, as well as the policing of nuclear sites. It made pioneering developments in nuclear (fission) power, overseeing the development of nuclear technology and performing much scientific research.
Trisops was an experimental machine for the study of magnetic confinement of plasmas with the ultimate goal of producing fusion power. The configuration was a variation of a compact toroid, a toroidal (doughnut-shaped) structure of plasma and magnetic fields with no coils penetrating the center. It lost funding in its original form in 1978. The configuration was produced by combining two individual toroids produced by two conical θ pinch guns, located at either end of a length of Pyrex pipe with a constant magnetic guide field.
The stability of structural materials in all nuclear reactors is a critical issue. Materials that can survive the high temperatures and neutron bombardment experienced in a fusion reactor are considered key to the success of developing nuclear fusion power systems. The principal issues are the conditions generated by the plasma, the problem of neutron degradation of wall surfaces, and so the issue of plasma-wall surface conditions. In addition, reducing Hydrogen permeability is seen as crucial to Hydrogen recycling and control a Tritium inventory.
After his retirement Tuck became a prominent public supporter of research into thermonuclear fusion for power generation. He also became interested in the phenomenon of ball lightning, probably because of the connection between plasmas and their role in fusion power schemes, and in 1980 he appeared in the Arthur C. Clarke's Mysterious World episode 'Clarke's Cabinet of Curiosities' where he described his experiments at Los Alamos, carried out during lunch breaks, to create ball lightning using a large storage battery of the type then used in submarines.
Closed- cycle gas turbines hold promise for use with future high temperature solar power and fusion power generation. They have also been proposed as a technology for use in long-term space exploration.Introduction to Gas Turbines for Non-Engineers (see page 5) Supercritical carbon dioxide closed-cycle gas turbines are under development; "The main advantage of the supercritical CO2 cycle is comparable efficiency with the helium Brayton cycle at significantly lower temperature" (550 °C vs. 850 °C), but with the disadvantage of higher pressure (20 MPa vs.
After completing his PhD, Britton spent two years in Oxford as a postdoctoral research associate studying materials for fission and fusion power. He received a fellowship in nuclear research in the faculty of engineering at Imperial College London in 2012. In 2015, he was appointed a lecturer in the centre for nuclear engineering at Imperial supported by a Royal Academy of Engineering fellowship establishing the "better understanding of materials to make safer reactors". , Britton is a senior lecturer in materials science and the centre for nuclear engineering.
This layout has been largely universal since then. One problem seen in all fusion reactors is that the presence of heavier elements causes energy to be lost at an increased rate, cooling the plasma. During the very earliest development of fusion power, a solution to this problem was found, the divertor, essentially a large mass spectrometer that would cause the heavier elements to be flung out of the reactor. This was initially part of the stellarator designs, where it is easy to integrate into the magnetic windings.
In 1951, Cockcroft arranged for the Oxford group to be transferred to Harwell. Cockcroft approved the construction of ZETA (Zero Energy Thermonuclear Assembly) by the Thonemann's Harwell group, and the smaller Sceptre by Allibone's AEI group. James L. Tuck's group at the Los Alamos Laboratory was also researching fusion, and Cockcroft struck an agreement with the Americans that they would release their results together, which was done in 1958. Despite Cockcroft's perennial optimism that a breakthrough was imminent, fusion power remained an elusive goal.
DIII-D, an experimental tokamak fusion reactor operated by General Atomics in San Diego, which has been used in research since it was completed in the late 1980s. The characteristic torus-shaped chamber is clad with graphite to help withstand the extreme heat. A tokamak (; ) is a device which uses a powerful magnetic field to confine a hot plasma in the shape of a torus. The tokamak is one of several types of magnetic confinement devices being developed to produce controlled thermonuclear fusion power.
Classical diffusion is a key concept in fusion power and other fields where a plasma is confined by a magnetic field. It considers collisions between ions in the plasma that cause the particles to move to different paths and eventually leave the confinement volume. It scales with 1/B2, where B is the magnetic field strength, implies that confinement times can be greatly improved with small increases in field strength. In practice, the rates suggested by classical diffusion have not been found in real-world machines.
Adding protons or removing neutrons increases the energy barrier. A mix of D-T at standard conditions does not undergo fusion; the nuclei must be forced together before the nuclear force can pull them together into stable collections. Even in the hot, dense center of the sun, the average proton will exist for billions of years before it fuses. For practical fusion power systems, the rate must be dramatically increased by heating the fuel to tens of millions of degrees, or compressing it to immense pressures.
Kenneth Chang, "Practical Fusion, or Just a Bubble?", New York Times, February 27, 2007JPL Contract 959962 , pg 8, and JPL Contract 960283 He believes that a dense plasma focus can also be used to produce useful aneutronic fusion energy.Patrick Huyghe, "3 Ideas That Are Pushing the Edge of Science", Discover Magazine, June 2008A Novel Form of Fusion Power, The Economist, October 22, 2009 Lerner explained his "Focus Fusion" approach in a 2007 Google Tech Talk. On November 14, 2008, Lerner received funding for continued research, to test the scientific feasibility of Focus Fusion.
Experiments and computer simulations to investigate the capability of DPF for fusion power are underway at Lawrenceville Plasma Physics (LPP) under the direction of Eric Lerner, who explained his "Focus Fusion" approach in a 2007 Google Tech Talk. On November 14, 2008, Lerner received funding for continued research, to test the scientific feasibility of Focus Fusion. On October 15, 2009, the DPF device "Focus Fusion-1" achieved its first pinch. On January 28, 2011, LPP published initial results including experimental shots with considerably higher fusion yields than the historical DPF trend.
Spherical Tokamak for Energy Production (STEP), is a spherical tokamak concept proposed by the United Kingdom Atomic Energy Authority and funded by UK government.uk-wants-to-build-worlds-first-fusion-power-plant-20-years-from-now 2019 The project aims to produce net electricity from fusion on a timescale of 2040. In September 2019 the United Kingdom announced a planned £200-million (US$248-million) investment to produce a design for a fusion facility named the Spherical Tokamak for Energy Production (STEP). The funding covers the initial five year concept design phase.
HT-7, or Hefei Tokamak-7, is an experimental superconducting tokamak nuclear fusion reactor built in Hefei, China, to investigate the process of developing fusion power. The HT-7 was developed with the assistance of Russia, and was based on the earlier T-7 tokamak reactor. The reactor was built by the Hefei- based Institute of Plasma Physics under the direction of the Chinese Academy of Sciences. The HT-7 construction was completed in May 1994, with final tests accomplished by December of the same year allowing experiments to proceed.
Sandia National Laboratory is currently investigating a z-pinch as a possible ignition source for inertial confinement fusion. On its "Z machine", Sandia can achieve dense, high temperature plasmas by firing fast, 100-nanosecond current pulses exceeding 20 million amps through hundreds of tungsten wires with diameters on the order of tens of micrometres. The LTD is currently being investigated as a driver for the next generation of high power accelerators. Sandia's roadmap includes another future Z machine version called ZN (Z Neutron) to test higher yields in fusion power and automation systems.
ZN is planned to give between 20 and 30 MJ of hydrogen fusion power with a shot per hour thanks to Russian Linear Transformer Driver (LTD) replacing the current Marx generators.Rapid-fire pulse brings Sandia’s Z method closer to goal of developing high-yield fusion reactor, Sandia's press release (April 27 , 2007). After 8 to 10 years of operation, ZN would become a transmutation pilot plant capable of a fusion shot every 100 seconds.Z-Inertial Fusion Energy: Power Plant Final Report FY 2006, Sandia Report SAND2006-7148 (October 2006).
Neoclassical transport, also known as neoclassical diffusion and often associated with banana orbits, is a type of diffusion seen in fusion power reactors. It is a modification of classical diffusion, adding in effects due to the geometry of the reactor that give rise to new diffusion effects. Classical transport models a plasma in a magnetic field as a large number of particles travelling in helical paths around a line of force. In typical reactor designs, the lines are roughly parallel, so particles orbiting adjacent lines may collide and scatter.
John Hopkin Nuckolls (born 17 November 1930) is an American physicist who worked his entire career at the Lawrence Livermore National Laboratory. He is best known for the development of inertial confinement fusion, which is a major branch of fusion power research to this day. He was also the lab's director from 1988 until 1994, when he resigned to become an Associate Director at Large. He was awarded the Ernest Orlando Lawrence Award in 1969, the James Clerk Maxwell Prize for Plasma Physics in 1981 and the Edward Teller Award in 1991.
After Spider-Man prevails, an embarrassed Beck assumes the identity of "Mysterio" and leads attacks on both an opera and the Statue of Liberty, which Spider-Man foils. He tracks down Mysterio to his apartment and overcomes another series of challenges, learning that Mysterio is a fraud, despite his escape. Harry introduces Peter to Dr. Otto Octavius, a nuclear scientist who is trying to make a fusion power experiment, sponsored by Oscorp, which would provide an unlimited source power to Manhattan. Octavius befriends and begins to mentor Peter.
Performance was significantly improved, allowing JET to set many records in terms of confinement time, temperature and fusion triple product. In 1997, JET set the record for the closest approach to scientific breakeven, reaching Q = 0.67 in 1997, producing 16 MW of fusion energy while injecting 24 MW of thermal power to heat the fuel. This is also the record for greatest fusion power produced. In 1998, JET's engineers developed a remote handling system with which, for the first time, it was possible to exchange certain components using artificial hands only.
Hydrogen is not an energy resource, except in the hypothetical context of commercial nuclear fusion power plants using deuterium or tritium, a technology presently far from development. The Sun's energy comes from nuclear fusion of hydrogen, but this process is difficult to achieve controllably on Earth. Elemental hydrogen from solar, biological, or electrical sources requires more energy to make than is obtained by burning it, so in these cases hydrogen functions as an energy carrier, like a battery. Hydrogen may be obtained from fossil sources (such as methane), but these sources are unsustainable.
Players could build highways, roads, bus depots, railway tracks, subways, train depots and zone land for seaports and airports. There are a total of nine varieties of power plants in SC2K, including coal, natural gas, wind turbines, hydroelectric dams (which can only be placed on waterfall tiles) and the futuristic fusion power and satellite microwave plant. The budget and finance controls are also much more elaborate—tax rates can be set individually for residential, commercial and industrial zones. Enacting city ordinances and connecting to neighboring cities became possible.
Since 2010, he has been a professor at the Department of Electrical Engineering and Computer Science at the Technical University of Munich. In 2013, he was appointed Full Professor for the Chair of Renewable and Sustainable Energy Systems. Thomas Hamacher takes part frequently in public debates about the German Energy transition in Germany, nuclear power and fusion power as an expert. His main research focus lies on the modeling, analysis, and design of energy systems in the context of disruptive technologies such as nuclear fusion, renewable energy, smart cities, or electromobility.
Slow Light (2011) is Perkowitz's fifth book of science nonfiction for popular audiences. Slow Light is a popular treatment of recent breakthroughs in the science of light. Even though the quantum mysteries of light are still not fully understood, it can be slowed to a stop and speeded up beyond its Einsteinian speed limit, 186,000 miles/sec; used for quantum telecommunications; teleported; manipulated to create invisibility; and perhaps used to generate hydrogen fusion power. Hollywood Science (2007) discusses the portrayal of science in more than one hundred films, including science fiction, scientific biographies, and documentaries.
Further experiments on ZETA showed that the original temperature measurements were misleading; the bulk temperature was too low for fusion reactions to create the number of neutrons being seen. The claim that ZETA had produced fusion had to be publicly withdrawn, an embarrassing event that cast a chill over the entire fusion establishment. The neutrons were later explained as being the product of instabilities in the fuel. These instabilities appeared inherent to any similar design, and work on the basic pinch concept as a road to fusion power ended by 1961.
The lab was the co-discoverer of new superheavy elements 113, 114, 115, 116, 117, and 118. The chemical element with atomic number 116 was given the name livermorium, after the laboratory, in 2012. LLNL is the location of the world's highest-energy laser, the National Ignition Facility (NIF), a project designed to create the first sustained, controlled nuclear fusion reaction, which would generate fusion power, a potential energy source. Livermore is also the California site of Sandia National Laboratories, which is managed and operated by a subsidiary of Honeywell International.
The High Power laser Energy Research facility (HiPER), is a proposed experimental laser-driven inertial confinement fusion (ICF) device undergoing preliminary design for possible construction in the European Union. , the effort appears to be inactive. HiPER was designed to study the "fast ignition" approach to generating nuclear fusion, which uses much smaller lasers than conventional ICF designs, yet produces fusion power outputs of about the same magnitude. This offers a total "fusion gain" that is much higher than devices like the National Ignition Facility (NIF), and a reduction in construction costs of about ten times.
In the case of NIF the laser generates about 4 MJ of infrared power to create ignition that releases about 20 MJ of energy. This corresponds to a "fusion gain" —the ratio of input laser power to output fusion power— of about 5. If one uses the baseline assumptions for the current HiPER design, the two lasers (driver and heater) produce about 270 kJ in total, yet generate 25 to 30 MJ, a gain of about 100. Considering a variety of losses, the actual gain is predicted to be around 72.
In 1962, Stix was elected Chair of the Division of Plasma Physics of the American Physical Society. He received a Guggenheim Fellowship in 1969, leading to the first of his three sabbaticals at the Weizmann Institute of Science in Israel. In 1980, the American Physical Society awarded Stix its highest honor in the plasma physics field, the James Clerk Maxwell Prize for Plasma Physics, for his pioneering role in developing and formalizing the theory of wave propagation and wave heating in plasmas. In 1999, he received the Lifetime Achievement Award by Fusion Power Associates.
The Princeton Large Torus (or PLT), was an early tokamak built at the Princeton Plasma Physics Laboratory (PPPL). It was one of the first large scale tokamak machines, and among the most powerful in terms of current and magnetic fields. A key feature was the use of external heating systems to raise the temperature of the plasma fuel, a requirement of any practical fusion power device. The tokamak became a topic of serious discussion in 1968, and the PPPL was convinced to convert their Model C stellarator to the tokamak configuration.
In existing (non-weapon) fusion experiments the heat produced by the fusion reactions rapidly escapes from the plasma, meaning that external heating must be applied continually in order to keep the reactions going. Ignition refers to the point at which the energy given off in the fusion reactions currently underway is high enough to sustain the temperature of the fuel against those losses. This causes a chain-reaction that allows the majority of the fuel to undergo a nuclear burn. Ignition is considered a key requirement if fusion power is to ever become practical.
Although the plasma in a fusion power station is expected to have a volume of or more, the plasma density is low and typically contains only a few grams of fuel in use. If the fuel supply is closed, the reaction stops within seconds. In comparison, a fission reactor is typically loaded with enough fuel for several months or years, and no additional fuel is necessary to continue the reaction. It is this large amount of fuel that gives rise to the possibility of a meltdown; nothing like this exists in a fusion reactor.
Peter Clive Thonemann (3 June 1917 – 10 February 2018) was an Australian-born British physicist who was a pioneer in the field of fusion power while working in the United Kingdom. Thonemann was born in Melbourne and moved to Oxford University in 1944, becoming one of the earliest researchers on the topic of controlled fusion. He led the fusion research at Oxford in its early years, before moving to the Atomic Energy Research Establishment (Harwell) in 1950. He led the ZETA reactor development at Harwell and announced its apparent success in 1958.
The explosion of the Ivy Mike hydrogen bomb. The hydrogen bomb is the only device able to achieve fusion energy gain factor significantly larger than 1. A fusion energy gain factor, usually expressed with the symbol Q, is the ratio of fusion power produced in a nuclear fusion reactor to the power required to maintain the plasma in steady state. The condition of Q = 1, when the power being released by the fusion reactions is equal to the required heating power, is referred to as breakeven, or in some sources, scientific breakeven.
New types of facilities include prisons, schools, libraries, museums, marinas, hospitals and arcologies. Players can build highways, roads, bus depots, railway tracks, subways, train depots and zone land for seaports and airports. There are a total of nine varieties of power plants in SimCity 2000, including coal, oil, natural gas, nuclear, wind turbines, hydroelectric dams (which can only be placed on waterfall tiles), solar and the futuristic fusion power and satellite microwave plant. Most types of power plants have a limited life span and must be rebuilt periodically.
Sceptre was an early fusion power device based on the Z-pinch concept of plasma confinement, built in the UK starting in 1957. They were the ultimate versions of a series of devices tracing their history to the original pinch machines, built at Imperial College London by Cousins and Ware in 1947. When the UK's fusion work was classified in 1950, Ware's team was moved to the Associated Electrical Industries (AEI) labs at Aldermaston. The team worked on the problems associated with using metal tubes with high voltages, in support of the efforts at Harwell.
Design challenges include the toroidal and poloidal field coils, vacuum vessels and plasma-facing components. This plasma configuration can confine a higher pressure plasma than a doughnut tokamak of high aspect ratio for a given, confinement magnetic field strength. Since the amount of fusion power produced is proportional to the square of the plasma pressure, the use of spherically shaped plasmas could allow the development of smaller, more economical and more stable fusion reactors. NSTX's attractiveness may be further enhanced by its ability to trap a high "bootstrap" electric current.
In every published fusion power plant design, the part of the plant that produces the fusion reactions is much more expensive than the part that converts the nuclear power to electricity. In that case, as indeed in most power systems, power density is an important characteristic.Comparing two different types of power systems involves many factors in addition to the power density. Two of the most important are the volume in which energy is produced in comparison to the total volume of the device, and the cost and complexity of the device.
Assume we have a very small reactor producing 30 kW of total fusion power (a full-scale power reactor might produce 100,000 times more than this) and 30 W in the form of neutrons. If there is no significant shielding, a worker in the next room, 10 m away, might intercept (0.5 m²)/(4 pi (10 m)2) = 4×10−4 of this power, i.e., 0.012 W. With 70 kg body mass and the definition 1 gray = 1 J/kg, we find a dose rate of 0.00017 Gy/s.
The International Thermonuclear Experimental Reactor, located in France, is the world's largest and most advanced experimental tokamak nuclear fusion reactor project. A collaboration between the European Union (EU), India, Japan, China, Russia, South Korea and the United States, the project aims to make a transition from experimental studies of plasma physics to electricity-producing fusion power plants. However, the World Nuclear Association says that nuclear fusion "presents so far insurmountable scientific and engineering challenges". Construction of the ITER facility began in 2007, but the project has run into many delays and budget overruns.
13 The other advantages have to do with the stability of the plasma. Since the earliest days of fusion research, the problem in making a useful system has been a number of plasma instabilities that only appeared as the operating conditions moved ever closer to useful ones for fusion power. In 1954 Edward Teller hosted a meeting exploring some of these issues, and noted that he felt plasmas would be inherently more stable if they were following convex lines of magnetic force, rather than concave.Robin Herman, "Fusion: The Search for Endless Energy", Cambridge University Press, 1990, pg.
The main source of materials degradation is structural damage which is typically quantified in terms of displacements per atom (dpa). Whereas in the currently constructed large fusion experiment, ITER, structural damage in the reactor steels will not exceed 2 dpa at the end of its operational life, damage creation in a fusion power plant is expected to amount to 15 dpa per year of operation. None of the commonly available neutron sources are adequate for fusion materials testing for various reasons. The accumulation of gas in the material microstructure is intimately related to the energy of the colliding neutrons.
Additional information on AESD and the other organizations within the now-defunct Advanced Power Systems Business Unit (APSBU) can be found in the article on the Westinghouse Astronuclear Laboratory (WANL). These include the Advanced Reactors Division (ARD) and Advanced Coal Conversion Department (ACCD), both of which were at the Waltz Mill site in Madison, Pa., and the Fusion Power Systems Department (FPSD), co- located with AESD at the Large site. In 1983, ARD was merged into AESD, and the Waste Technology Services Division (WTSD) was created at the Large site to vie for contracts related to disposal of nuclear waste.
Due to fusion, the composition of the solar plasma drops from 68–70% hydrogen by mass at the outer core, to 34% hydrogen at the core/Sun center. The core inside 0.20 of the solar radius contains 34% of the Sun's mass, but only 0.8% of the Sun's volume. Inside the 0.24 solar radius is the core which generates 99% of the fusion power of the Sun. There are two distinct reactions in which four hydrogen nuclei may eventually result in one helium nucleus: the proton-proton chain reaction – which is responsible for most of the Sun's released energy – and the CNO cycle.
Inertial confinement fusion is one of two major lines of fusion power development, the other being magnetic confinement fusion (MCF), notably the tokamak concept which is being built in a major experimental system known as ITER. Magnetic confinement is widely considered to be the superior approach, and has seen significantly greater development activity over the decades. However, there are serious concerns that the MCF approach of ITER cannot ever become economically practical. One of the cost concerns for MCF designs like ITER is that the reactor materials are subject to the intense neutron flux created by the fusion reactions.
Host Garry Moore then spent a few minutes discussing with Farnsworth his research on such projects as an early analog high-definition television system, flat-screen receivers, and fusion power. Farnsworth said, "There had been attempts to devise a television system using mechanical disks and rotating mirrors and vibrating mirrors—all mechanical. My contribution was to take out the moving parts and make the thing entirely electronic, and that was the concept that I had when I was just a freshman in high school in the Spring of 1921 at age 14."Farnsworth, Elma G., p. 37.
Figure 7: Plot of the cross section of different fusion reactions. Nuclear fusion refers to nuclear reactions that combine lighter nuclei to become heavier nuclei. All chemical elements can be fused; for elements with fewer protons than iron, this process changes mass into energy that can potentially be captured to provide fusion power. The probability of a fusion reaction occurring is controlled by the cross section of the fuel,"Development of the indirect drive approach to inertial confinement fusion and the target physics basis for ignition and gain" John Lindl, Physics of Plasma, 1995 which is in turn a function of its temperature.
He was an author of laws that authorized efforts which included matters such as solar energy, electric cars and fusion power, and his expertise on overall energy issues was acknowledged by Members of Congress of both political parties. McCormack was a cosponsor in a successful attempt to pass legislation intended to facilitate general conversion of the United States to the metric system of measurement. HR 8674, the Metric Conversion Act of 1975, was ultimately signed by President Ford into public law 94-168. At times, McCormack took positions that were critical of the policies advocated by presidents and administrations of both political parties.
For example, a 1.46 kW Nd:YAG laser has been demonstrated by Konoshima Chemical Co. in Japan. In addition, Livermore researchers realized that these fine-grained ceramic nanomaterials might greatly benefit high-powered lasers used in the National Ignition Facility (NIF) Programs Directorate. In particular, a Livermore research team began to acquire advanced transparent nanomaterials from Konoshima to determine if they could meet the optical requirements needed for Livermore's Solid-State Heat Capacity Laser (SSHCL). Livermore researchers have also been testing applications of these materials for applications such as advanced drivers for laser-driven fusion power plants.
Firing the Z-machine has become a way to test very high energy, high temperature (2 billion degrees) conditions. In 1996, the Tore Supra creates a plasma for two minutes with a current of almost 1 million amperes driven non-inductively by 2.3 MW of lower hybrid frequency waves. This is 280 MJ of injected and extracted energy. This result was possible because of the actively cooled plasma-facing components In 1997, JET produced a peak of 16.1 MW of fusion power (65% of heat to plasmaFUSION RESEARCH An Energy Option for An Energy Option for Europe's Future , pa.
In 1974 a study of the ZETA results demonstrated an interesting side-effect; after an experimental run ended, the plasma would enter a short period of stability. This led to the reversed field pinch concept, which has seen some level of development since. On May 1, 1974, the KMS fusion company (founded by Kip Siegel) achieves the world's first laser induced fusion in a deuterium-tritium pellet. In the mid-1970s, Project PACER, carried out at Los Alamos National Laboratory (LANL) explored the possibility of a fusion power system that would involve exploding small hydrogen bombs (fusion bombs) inside an underground cavity.
Laboratory scale Z-pinch showing glow from an expanded hydrogen plasma. Pinch and ionisation current flows through the gas and returns via the bars surrounding the plasma vessel. In fusion power research, the Z-pinch, also known as zeta pinch, is a type of plasma confinement system that uses an electrical current in the plasma to generate a magnetic field that compresses it (see pinch). These systems were originally referred to simply as pinch or Bennett pinch (after Willard Harrison Bennett), but the introduction of the θ-pinch concept led to the need for increased clarity.
Additionally, fusion fuels, especially tritium, are very expensive, so many experiments run on various test gasses like hydrogen or deuterium. A reactor running on these fuels that reaches the conditions for breakeven if tritium was introduced is said to be operating at extrapolated breakeven. , the record for Q is held by the JET tokamak in the UK, at Q = (16 MW)/(24 MW) ≈ 0.67, first attained in 1997. ITER was originally designed to reach ignition, but is currently designed to reach Q = 10, producing 500 MW of fusion power from 50 MW of injected thermal power.
Magnetized target fusion (MTF) is a fusion power concept that combines features of magnetic confinement fusion (MCF) and inertial confinement fusion (ICF). Like the magnetic approach, the fusion fuel is confined at lower density by magnetic fields while it is heated into a plasma. As with the inertial approach, fusion is initiated by rapidly squeezing the target to greatly increase fuel density and temperature. Although the resulting density is far lower than in ICF, it is thought that the combination of longer confinement times and better heat retention will let MTF operate, yet be easier to build.
McLaughlin has also worked with the jazz composers Carla Bley and Gil Evans. McLaughlin performing in The Netherlands, 1978 In 1979 he formed a short-lived funk fusion power trio named Trio of Doom with drummer Tony Williams and bassist Jaco Pastorius. Their only live performance was on 3 March 1979 at the Havana Jam Festival (2–4 March 1979) in Cuba, part of a US State Department sponsored visit to Cuba. Later on 8 March 1979 the group recorded the songs they had written for the festival at Columbia Studios, New York, on 52nd Street.
Protons demanded another accelerator, PBFA-II, which became Z. In the December 1976 issue of Popular Science and in 1976 conference proceedings published in 1977, an article titled "Particle Beam Fusion Research" described early work and first generation machines: Hydra (1972); Proto I (1975); Proto II (1977); EBFA/PBFA (electronic beam fusion accelerator/particle beam fusion accelerator) (1980). In 1985, the PBFA-II was created. Sandia continued to target heavy ion fusion at a slow pace despite the National Academies report. The November 1978 issue of Scientific American carried Yonas' first general-public article, "Fusion power with particle beams".
Lithium-6–deuterium fusion reaction: an aneutronic fusion reaction, with energy released carried by alpha particles, not neutrons. Aneutronic fusion is any form of fusion power in which very little of the energy released is carried by neutrons. While the lowest-threshold nuclear fusion reactions release up to 80% of their energy in the form of neutrons, aneutronic reactions release energy in the form of charged particles, typically protons or alpha particles. Successful aneutronic fusion would greatly reduce problems associated with neutron radiation such as damaging ionizing radiation, neutron activation, and requirements for biological shielding, remote handling and safety.
Zubrin, in his 1996 book (revised 2011) The Case for Mars, acknowledges any Martian colony will be partially Earth-dependent for centuries. However, Zubrin suggests Mars may be profitable for two reasons. First, it may contain concentrated supplies of metals equal to or of greater value than silver, which have not been subjected to millennia of human scavenging; it is suggested such ores may be sold on Earth for profit. Secondly, the concentration of deuterium—an extremely expensive but essential fuel for the as-yet non-existent nuclear fusion power industry—is five times greater on Mars.
Fusion is another area with a history of research at ORNL, dating back to the 1970s. The Fusion Energy Division pursues short-term goals to develop components such as high temperature superconductors, high-speed hydrogen pellet injectors and suitable materials for future fusion research. Much research into the behaviour and maintenance of a plasma takes place at the Fusion Energy Division to further the understanding of plasma physics, a crucial area for developing a fusion power plant. The US ITER office is at ORNL with partners at Princeton Plasma Physics Laboratory and Savannah River National Laboratory.
However, layers of the Sun are radiating to outer layers only slightly lower in temperature, and it is this difference in radiation powers between layers which determines net power generation and transfer in the solar core. At 19% of the solar radius, near the edge of the core, temperatures are about 10 million kelvins and fusion power density is 6.9 W/m3, which is about 2.5% of the maximum value at the solar center. The density here is about 40 g/cm3, or about 27% of that at the center.see p 54 and 55 Some 91% of the solar energy is produced within this radius.
The codes and associated datasets were selected for benchmarking systems with peak performances ranging up to hundreds of teraflops, machines which are more powerful than a desktop personal computer by factors of tens of thousands. The suite contained codes relevant to astrophysics, fluid dynamics, climate modelling, biosciences, materials science, fusion power and fundamental particle physics. It has been run by DEISA on a range of its own supercomputers and records of the results are kept for comparison. The DEISA benchmark was used by the EU-funded PRACE project as a starting point for their investigations of benchmarks for the next generation of petaflop supercomputers.
Facts and Stats... 1/3 of fuel rods changed every 18 months. STPNOC.com. Moreover, some detritiation systems will be implemented, so that, at a fuel cycle inventory level of about , ITER will eventually need to recycle large amounts of tritium and at turnovers orders of magnitude higher than any preceding tritium facility worldwide. In the case of an accident (or sabotage), it is expected that a fusion reactor would release far less radioactive pollution than would an ordinary fission nuclear station. Furthermore, ITER's type of fusion power has little in common with nuclear weapons technology, and does not produce the fissile materials necessary for the construction of a weapon.
One of the earliest photos of the kink instability in action - the 3 by 25 cm pyrex tube at Aldermaston. A kink instability (also kink oscillation or kink mode), is a current-driven plasma instability characterized by transverse displacements of a plasma column's cross-section from its center of mass without any change in the characteristics of the plasma. It typically develops in a thin plasma column carrying a strong axial current which exceeds the Kruskal–Shafranov limit and is sometimes known as the Kruskal–Shafranov (kink) instability. The kink instability was first widely explored in fusion power machines with Z-pinch configurations in the 1950s.
Without prejudice to the cause of religion, I may remark that theological discussions have not at all times been distinguished by their character of lucidity. The historical Technology Review often published articles that were controversial, or critical of certain technologies. A 1980 issue contained an article by Jerome Wiesner attacking the Reagan administration's nuclear defense strategy. The cover of a 1983 issue stated "Even if the fusion program produces a reactor, no one will want it," and contained an article by Lawrence M. Lidsky, associate director of MIT's Plasma Fusion Center, challenging the feasibility of fusion power (which at the time was often fancied to be just around the corner).
He continued his work on accelerators and led the project to build the Variable Energy Cyclotron (for AERE Harwell). He had responsibility for building up the superconducting magnet programme and retained an interest in new accelerator concepts. In the 1970s he moved onto the study of very high current beams and in 1977 his book The Physics of Charged Particle Beams was published (second edition 1989), which became a classic textbook on particle accelerators. In 1975-1976 Lawson returned to fusion research with a two-year sabbatical at the Culham Laboratory, working on a design study of a conceptual fusion power reactor based on the reversed field pinch principle.
From 1959, Postma was a full- time researcher at Oak Ridge National Laboratory (ORNL), largely focused on plasma physics with the goal of achieving fusion power. Notably, he developed the neutral beam injection technique; shooting a beam of high energy atoms into plasma to initiate fusion, as well as other methods of heating plasma stochastically in fusion reactors. Early in his career at ORNL he was working under Clarence Barnett, measuring the cross sections of nuclear species, whom Postma proved wrong by identifying inconsistencies in his measurements. By 1961 Postma was involved directly in plasma physics research and in 1968 he became director of Oak Ridge National Laboratory's Thermonuclear Division (fusion).
The Trio of Doom was a short-lived jazz fusion power trio consisting of John McLaughlin on guitar, Jaco Pastorius on bass, and Tony Williams on drums. They were brought together by Columbia Records in 1979 to play the Havana Jam festival in Cuba alongside Billy Joel, Kris Kristofferson, Rita Coolidge, and others. Their only live performance was on March 3, 1979, and it is recorded on Ernesto Juan Castellanos's documentary Havana Jam '79. On March 8, 1979, the group reconvened in New York City to record the songs they had played live, but a dispute broke out between Pastorius and Williams that ended the trio.
Leading candidate neutron multiplication materials are beryllium and lead however the 7Li reaction above also helps to keep the neutron population high. Natural lithium is mainly 7Li however this has a low tritium production cross section compared to 6Li so most reactor designs use breeder blankets with enriched 6Li. Several drawbacks are commonly attributed to D-T fusion power: # It produces substantial amounts of neutrons that result in the neutron activation of the reactor materials.:242 # Only about 20% of the fusion energy yield appears in the form of charged particles with the remainder carried off by neutrons, which limits the extent to which direct energy conversion techniques might be applied.
At Los Alamos, Tuck took up research on fusion power, which he had learned about in the UK. Tuck suggested that the Los Alamos group pursue a pinch program similar to the one being carried out in the UK. This was only months after Lyman Spitzer had started work on his stellarator design. Both were invited to Washington to present their ideas, where Spitzer won $50,000 in funding from the Atomic Energy Commission. Returning to Los Alamos, he arranged for a similar $50,000 from the lab's discretionary budget and started a pinch project under the name Perhapsatron. Like all pinch systems, Perhapsatron failed due to instabilities in the plasma.
An early photograph of the kink instability in a toroidal pinch - the 3 by 25 pyrex tube at Aldermaston. Pinch devices were among the earliest efforts in fusion power. Research began in the UK in the immediate post-war era, but a lack of interest led to little development until the 1950s. The announcement of the Huemul Project in early 1951 led to fusion efforts around the world, notably in the UK and in the US. Small experiments were built at labs as various practical issues were addressed, but all of these machines demonstrated unexpected instabilities of the plasma that would cause it to hit the walls of the container vessel.
The Difference Between an FRC and a Spheromak Producing fusion power by confining the plasma with magnetic fields is most effective if the field lines do not penetrate solid surfaces but close on themselves into circles or toroidal surfaces. The mainline confinement concepts of tokamak and stellarator do this in a toroidal chamber, which allows a great deal of control over the magnetic configuration, but requires a very complex construction. The field-reversed configuration offers an alternative in that the field lines are closed, providing good confinement, but the chamber is cylindrical, allowing simpler, easier construction and maintenance. Field-reversed configurations and spheromaks are together known as compact toroids.
In 1997, scientists at the Joint European Torus (JET) facilities in the UK produced 16 megawatts of fusion power. Scientists can now exercise a measure of control over plasma turbulence and resultant energy leakage, long considered an unavoidable and intractable feature of plasmas. There is increased optimism that the plasma pressure above which the plasma disassembles can now be made large enough to sustain a fusion reaction rate acceptable for a power plant. Electromagnetic waves can be injected and steered to manipulate the paths of plasma particles and then to produce the large electrical currents necessary to produce the magnetic fields to confine the plasma.
Hybrid nuclear power is a proposed means of generating power by use of a combination of nuclear fusion and fission processes. The concept dates to the 1950s, and was briefly advocated by Hans Bethe during the 1970s, but largely remained unexplored until a revival of interest in 2009, due to delays in the realization of pure fusion. When a sustained nuclear fusion power plant is built, it has the potential to be capable of extracting all the fission energy that remains in spent fission fuel, reducing the volume of nuclear waste by orders of magnitude, and more importantly, eliminating all actinides present in the spent fuel, substances which cause security concerns.
As controlled nuclear fusion has proven difficult to use as an energy source, an alternate proposal for producing fusion power has been to detonate nuclear fusion explosives inside very large underground chambers and then using the heat produced, which would be absorbed by a molten salt coolant which would also absorb neutrons. The 1970s PACER (fusion) project investigated fusion detonation as a power source. Failure to meet objectives, along with the realization of the dangers of nuclear fallout and other residual radioactivity, and with the enactment of various agreements such as the Partial Test Ban Treaty and the Outer Space Treaty, has led to the termination of most of these programs.
Ignitor is part of the line of research on high magnetic field, experiments producing high density plasmas that began with the Alcator and the Frascati Torus programs at MIT and in Italy, respectively. It remains, at the world level, the only experiment capable of reaching ignition by the magnetic field confinement approach. However, several fusion scientists have contested the claim made for IGNITOR that it is a bigger step towards fusion power than the international ITER project. According to existing plans, Ignitor will be installed at the Triniti site at Troitsk near Moscow that has facilities which can be upgraded to house and operate the machine.
The Astron is a type of fusion power device pioneered by Nicholas Christofilos and built at the Lawrence Livermore National Laboratory during the 1960s and 70s. Astron used a unique confinement system that avoided several of the problems found in contemporary designs like the stellarator and magnetic mirror. Development was greatly slowed by a series of changes to the design that were made with limited oversight, leading to a review committee being set up to oversee further development. The Astron was unable to meet the performance goals set for it by the committee; funding was cancelled in 1972 and development wound down in 1973.
A later examination of the topic concluded: "there is no evidence in Strauss's papers at the Herbert Hoover Presidential Library to indicate fusion was the hidden subject of his speech." Strauss viewed hydrogen fusion as the ultimate power source and was eager to develop the technology as quickly as possible and urged the Project Sherwood researchers to make rapid progress, even suggesting a million-dollar prize to the individual or team that succeeded first.Bromberg, Joan Lisa (1982) Fusion: Science, Politics, and the Invention of a New Energy Source MIT Press, Cambridge, Massachusetts, p. 44, However Strauss was not optimistic about the rapid commercialization of fusion power.
During deuterium (D–D fuel) plasma experiments in 1998, plasma conditions were achieved which would have achieved break-even—the point where the power produced by the fusion reactions equals the power supplied to operate the machine—if the D–D fuel were replaced with a 1:1 mix of deuterium and tritium (D–T fuel). JT-60 does not have the facilities to handle tritium; only the JET tokamak in the United Kingdom has such facilities as of 2018. In fusion terminology, JT-60 achieved conditions which in D–T would have provided a fusion energy gain factor (the ratio of fusion power to input power) Q = 1.25.Daniel Clery.
Derek Charles Robinson FRS (27 May 1941 – 2 December 2002) was a physicist who worked in the UK fusion power program for most of his professional career. Studying turbulence in the UK's ZETA reactor, he helped develop the reversed field pinch concept, an area of study to this day. He is best known for his role in taking a critical measurement on the T-3 device in the USSR in 1969 that established the tokamak as the primary magnetic fusion energy device to this day. He was also instrumental in the development of the spherical tokamak design though the construction of the START device, and its follow-on, MAST.
A stellarator is a magnetic confinement fusion device which generates all required magnetic fields to confine high temperature plasma by external magnetic coils. In contrast, in tokamaks and reversed field pinches, the magnetic field is created by the interaction of external magnets and an electrical current flowing through the plasma. The lack of this large externally driven plasma current makes stellarators suitable for steady-state fusion power plants. However, due to non-axisymmetric nature of the fields, conventional stellarators have a combination of toroidal and helical modulation of the magnetic field lines, which leads to high transport of plasma out of the confinement volume at fusion-relevant conditions.
In the revived show, the Control Voice was supplied by Kevin Conway. The new series distanced itself from the "monster of the week" mandate that had characterized the original series from its inception; while there were plenty of aliens and monsters, they dramatize a specific scientific concept and its effect on humanity. Examples of this include "Dark Rain" (biochemical warfare causing worldwide sterility), "Final Exam" (discovery of practical cold fusion power), "A Stitch in Time" (a time traveler tinkers with history), as well as two episodes revolving around a human mutation known as Genetic Rejection Syndrome (humans mutating into violent creatures) as a result of an outlawed eugenics attempt to create superior children.
The ITER parties had agreed to provide contributions to ITER through legal entities referred to as "Domestic Agencies". Europe has fulfilled its obligation by launching the European Domestic Agency called "Fusion for Energy", also called F4E, in March 2007. With the appearance of F4E EFDA´s role has changed and it has been reorganised. A revised European Fusion Development Agreement entered into force on 1 January 2008 focuses on research coordination with two main objectives: to prepare for the operation and exploitation of ITER and to further develop and consolidate the knowledge base needed for overall fusion development and in particular for DEMO, the first electricity producing experimental fusion power plant being built after ITER.
Several wildly unsuccessful investments by Guccione—including the Penthouse Boardwalk Hotel and Casino (which lost $160 million) and a (never-built) nuclear fusion power plant—added to his publishing empire's financial woes.Rolling Stone, "The Twilight of Bob Guccione"; accessed October 20, 2010. Guccione's efforts to regain sales and notoriety, which included attempts to get Monica Lewinsky to pose for the magazine (which was parodied in a sketch on Saturday Night Live in 1998Saturday Night Live website ) and offering the Unabomber a free forum for his views, failed to increase readership. With the rise of online access to (often free) pornography in the late 1990s, Penthouse's circulation numbers began to suffer even more.
See test shot "Taiga". The repeated detonation of nuclear devices underground in salt domes, in a somewhat analogous manner to the explosions that power a car’s internal combustion engine (in that it would be a heat engine), has also been proposed as a means of fusion power in what is termed PACER.John Nuckolls, "Early Steps Toward Inertial Fusion Energy (IFE)", LLNL, June 12, 1998Ralph Moir, PACER development Other investigated uses for low- yield peaceful nuclear explosions were underground detonations to stimulate, by a process analogous to fracking, the flow of petroleum and natural gas in tight formations; this was developed most in the Soviet Union, with an increase in the production of many well heads being reported.
Their analysis showed that the forces due to the interaction of the large current flow with its own magnetic field could have caused the compression and distortion.R. S. Pease, "The Electromagnetic Pinch: From Pollock to the Joint European Torus", "Pollock Memorial Lecture for 1984 delivered at the University of Sydney, 28 November, 1984" A similar, and apparently independent, theoretical analysis of the pinch effect in liquid metals was published by Northrupp in 1907. The next major development was the publication in 1934 of an analysis of the radial pressure balance in a static Z-pinch by Bennett (see the following section for details). Thereafter, the experimental and theoretical progress on pinches was driven by fusion power research.
The objective of Astro Battle is to destroy other player's ships in multi-player online matches. The game features standard Multi- directional shooter gameplay with several innovations. Astro Battle's gameplay deviates from that of traditional Shoot 'em ups in that, rather than provide pre-designed space ships which are then customised by a limited selection of weapons on pre-selected hardpoints, players must design a star fighter in the included ship editor. Astro Battle gives you a large number of parts, including cockpits, trusses, thrusters, guns, batteries and fusion power reactors, each with their own attributes, and the attributes of spacecraft are determined entirely by the modules used in construction and the arrangement of these modules.
HiPER is currently studying devices that operate at 1 MJ at 1 Hz, or alternately 100 kJ at 10 Hz. R&D; continued on inertial fusion energy in the European Union and in Japan. The High Power laser Energy Research (HiPER) facility is a proposed experimental fusion device undergoing preliminary design for possible construction in the European Union to continue the development of laser-driven inertial confinement approach. HiPER is the first experiment designed specifically to study the fast ignition approach to generating nuclear fusion. Using much smaller lasers than conventional designs, yet produces fusion power outputs of about the same magnitude would offer a much higher Q with a reduction in construction costs of about ten times.
Several groups proposed that fusion power based on the DPF could be economically viable, possibly even with low-neutron fuel cycles like p-B11. The feasibility of net power from p-B11 in the DPF requires that the bremsstrahlung losses be reduced by quantum mechanical effects induced by an extremely strong magnetic field "frozen into the plasma". The high magnetic field also results in a high rate of emission of cyclotron radiation, but at the densities envisioned, where the plasma frequency is larger than the cyclotron frequency, most of this power will be reabsorbed before being lost from the plasma. Another advantage claimed is the capability of direct conversion of the energy of the fusion products into electricity, with an efficiency potentially above 70%.
Spider-Man 2 is a 2004 action-adventure game, based on the film of the same name, while incorporating additional material from the comic books. It is a follow-up to the 2002 game Spider-Man, itself based on the 2002 film, and incorporates various references to the events of that game. Published by Activision, the console versions were developed by Treyarch; other versions had different developers. All versions of the game follow and expand on the film's plot, which depicts Spider-Man's conflict with his former mentor, Dr. Otto Octavius, now the supervillain Doctor Octopus, who plans to recreate a fusion power experiment that will destroy New York City, while dealing with the personal problems of his civilian persona, Peter Parker.
By the early 1960s, the fusion power field had grown large enough that the researchers began organizing semi-annual meetings that rotated around the various research establishments. In 1968, the now-annual meeting was held in Novosibirsk, where the Soviet delegation surprised everyone by claiming their tokamak designs had reached performance levels at least an order of magnitude better than any other device. The claims were initially met with skepticism, but when the results were confirmed by a UK team the next year, this huge advance led to a "virtual stampede" of tokamak construction. In the US, one of the major approaches being studied up to this point was the stellarator, whose development was limited almost entirely to the PPPL.
In June EMC2 demonstrated for the first time that the electron cloud becomes diamagnetic in the center of a magnetic cusp configuration when beta is high, resolving an earlier conjecture. Whether the plasma is thermalized remains to be demonstrated experimentally. Park presented these findings at various universities,"Polywell Fusion – Electric Fusion in a Magnetic Cusp" Jaeyoung Park, Friday, December 5, 2014 - 1:00pm to 2:00pm, Physics and Astronomy Building (PAB) Room 4-330, UCLATalk at University of Wisconsin Madison, Monday, June 16, 2:30 PM room 106 ERB, Jaeyoung ParkUniversity of Maryland, Colloquium & Seminars, "Measurement of Enhanced Confinement at High Pressure Magnetic Cusp System", Jaeyoung Park, September 9th 2014 the Annual 2014 Fusion Power Associates meeting and the 2014 IEC conference.
Two years after the first film, Peter struggles to maintain his personal life while serving as Spider-Man, getting fired from a second job he takes as a pizza delivery boy while simultaneously struggling with his studies at Columbia University and his finances. He is also growing distant from his two friends, Harry and Mary Jane, who have found success as the new CEO of Oscorp and a Broadway actress, respectively, and discovers Aunt May is facing foreclosure of her home after his surprise birthday party. Harry introduces Peter to his idol Dr. Otto Octavius, whose research Oscorp is funding, prior to a demonstration of Octavius' work on fusion power. During the demonstration, Octavius dons a harness with four robotic arms and artificial intelligence.
The United Kingdom Atomic Energy Authority (UKAEA) was established in 1954 as a UK government research organization responsible for the development of nuclear fusion power. The National Non-Destructive Testing Centre (NNDTC) was created at UKAEA's Harwell research establishment in 1967. The center's formation created a central NDT research base in the UK. In 1982 from within the NNDTC the Harwell Offshore Inspection Service (HOIS) was formed as a joint industry project to improve the effectiveness of in-service inspection for the oil and gas industry. The UKAEA's Safety and Risk Directorate was at the forefront of developments such as Quantified Risk Assessment (QRA) that were transferred from the nuclear industry and applied within major hazard industries such as petrochemical, process, and oil and gas.
Under the command of a new Führer (who is referred to as "Chancellor", and his real name is never revealed), Operation Sealion succeeds and the Nazis successfully conquer Britain, sparking a cold war between the Allied Powers and Germany. The Fallout series of computer role-playing games is set in a divergent America, where history after World War II diverges from the real world to follow a retro-futuristic timeline. For example, fusion power was invented quite soon after the end of the war, but the transistor was never developed. The result was a future that has a 1950s 'World of Tomorrow' feel to it, with extremely high technology such as artificial intelligence implemented with thermionic valves and other technologies now considered obsolete.
As the surviving power blocs of Earth before the conflict are still evident, North America, Europe and Asia each send a generation ship to Alpha Centauri to take control of the colony. By the time that the first generation ship (the American Mayflower II) arrives after 20 years, Chironian society is in its fifth generation. The Mayflower II has brought with it thousands of settlers, all the trappings of the authoritarian regime along with bureaucracy, religion, fascism and a military presence to keep the population in line. However, the planners behind the generation ship did not anticipate the direction that Chironian society took: in the absence of conditioning and with limitless robotic labor and fusion power, Chiron has become a post-scarcity economy.
Mockup of a gold-plated hohlraum designed for use in the National Ignition Facility In 1991 the Preliminary Tritium Experiment at the Joint European Torus in England achieved the world's first controlled release of fusion power. In 1992, a major article was published in Physics Today by Robert McCory at the Laboratory for laser energetics outlying the current state of ICF and advocating for a national ignition facility. This was followed up by a major review article, from John Lindl in 1995, advocating for NIF. During this time a number of ICF subsystems were developing, including target manufacturing, cryogenic handling systems, new laser designs (notably the NIKE laser at NRL) and improved diagnostics like time of flight analyzers and Thomson scattering.
There are some power station ideas that may significantly lower the cost or size of such stations; however, research in these areas is not as advanced as in tokamaks. Fusion power commonly proposes the use of deuterium, an isotope of hydrogen, as fuel and in many current designs also use lithium. Assuming a fusion energy output equal to the 1995 global power output of about 100 EJ/yr (= 1 × 1020 J/yr) and that this does not increase in the future, which is unlikely, then the known current lithium reserves would last 3000 years. Lithium from sea water would last 60 million years, however, and a more complicated fusion process using only deuterium would have fuel for 150 billion years.
Fusion includes energy from the sun which will be available for billions of years (in the form of sunlight) but so far (2018), sustained fusion power production continues to be elusive. Power from fission of uranium and thorium in nuclear power plants will be available for many decades or even centuries because of the plentiful supply of the elements on earth, though the full potential of this source can only be realised through breeder reactors, which are, apart from the BN-600 reactor, not yet used commercially. Coal, gas, and petroleum are the current primary energy sources in the U.S. but have a much lower energy density. Burning local biomass fuels supplies household energy needs (cooking fires, oil lamps, etc.) worldwide.
After the success of the fusion experiments, it was enlarged and renamed ORMAK II in 1973; however, the experiments ultimately failed to lead to fusion power plants. The US Atomic Energy Commission required improved safety standards in the early 1970s for nuclear reactors, so ORNL staff wrote almost 100 requirements covering many factors including fuel transport and earthquake resistance. In 1972 the AEC held a series of public hearings where emergency cooling requirements were highlighted and the safety requirements became more stringent. ORNL was involved in analysing the damage to the core of the Three Mile Island Nuclear Generating Station after the accident in 1979. Also in 1972, Peter Mazur, a biologist at ORNL, froze with liquid nitrogen, thawed and implanted mouse embryos in a surrogate mother.
This work demonstrated that certain shapes strongly suppressed a variety of instabilities in the plasma, which led to much higher plasma pressure and performance. DIII-D is so-named because the plasma is shaped like the letter D, a shaping that is now widely used on modern designs, and has led to the class of machines known as "advanced tokamaks." Advanced tokamaks are characterized by operation at high plasma β through strong plasma shaping, active control of various plasma instabilities, and achievement of steady-state current and pressure profiles that produce high energy confinement for high fusion gain (ratio of fusion power to heating power). DIII-D is one of two large magnetic fusion experiments in the U.S. (the other being NSTX-U at PPPL) supported by the U.S. Department of Energy Office of Science.
Glidcop uses include resistance welding electrodes to prevent them from sticking to galvanized and other coated steels. It has also been used in applications where its resistance to softening at high temperatures is necessary, including incandescent light bulb, leads relay blades, contactor supports, x-ray tube components, heat exchanger sections for fusion power and synchrotron units, high field magnetic coils, sliding electrical contacts, arc welder electrodes, electronic leadframes, MIG contact tips, commutators, high speed motor and generator components, and microwave power tube components. Glidcop has also been used in hybrid circuit packages due to its compatibility with high temperature brazing, and in particle accelerator components, such as radio frequency quadrupoles and compact X-ray absorbers for undulator beam lines, where the alloy may be subjected to high temperatures and high radiation simultaneously.
From 1969 to 1973, Anders served as Executive Secretary for the National Aeronautics and Space Council, which was responsible to the President, Vice President and Cabinet-level members of the Council for developing policy options concerning research, development, operations and planning of aeronautical and space systems. On August 6, 1973, he was appointed to the five-member Atomic Energy Commission, where he was lead commissioner for nuclear and non-nuclear power research and development. He was also named as U.S. Chairman of the joint U.S./USSR technology exchange program for fission and fusion power. Following the reorganization of national nuclear regulatory and developmental activities on January 19, 1975, he was named by President Ford to become the first chairman of the newly established Nuclear Regulatory Commission, which is responsible for nuclear safety and environmental compatibility.
It is the goal of a fusion power station to harness this energy to produce electricity. Activation energies (in most fusion systems this is the temperature required to initiate the reaction) for fusion reactions are generally high because the protons in each nucleus will tend to strongly repel one another, as they each have the same positive charge. A heuristic for estimating reaction rates is that nuclei must be able to get within 100 femtometers (1 × 10−13 meter) of each other, where the nuclei are increasingly likely to undergo quantum tunneling past the electrostatic barrier and the turning point where the strong nuclear force and the electrostatic force are equally balanced, allowing them to fuse. In ITER, this distance of approach is made possible by high temperatures and magnetic confinement.
As an expert in geological research on underground nuclear tests and extraterrestrial materials, Ouyang was among the first to advocate not only the exploitation of lunar reserves of metals such as iron, but also the mining of lunar helium-3, an ideal fuel for nuclear fusion power plants. Ouyang is now the chief scientist of the Chinese Lunar Exploration Program (CLEP), also known as the Chang'e program. He is the most prominent supporter of the Chinese manned lunar exploration program, and also lobbies for the Chinese exploration of Mars. On November 12, 2008, upon China's publication of a comprehensive lunar surface map, Ouyang encouraged all three Asian nations then involved in lunar exploration (China, India and Japan) to increase co- operation in furthering humanity's understanding of the Moon.
The ULS (UMIST Linear System) is a gas target divertor simulator located on the former UMIST campus of the University of Manchester. It enables physicists to study the recombination processes of a detached plasma in a hydrogen target chamber. Research on detached plasma and on its recombination modes is of primary importance in order to design an appropriate divertor region in a future nuclear fusion power plant, where huge amounts of energy will be deposited by the fast-moving particles generated in the main reactor. The major goal of the ULS as for many other linear divertor simulators, is to reproduce the same temperature and density conditions of the SOL (Scrape Off Layer) of a tokamak in a linear environment and therefore to make easier the study of its properties.
Stellarators are one of the first fusion power concepts, originally designed by Princeton astrophysicist Lyman Spitzer in 1952 while riding the chairlifts at Aspen. Spitzer, considering the motion of plasmas in the stars, realized that any simple arrangements of magnets would not confine a plasma inside a machine - the plasma would drift across the fields and eventually strike the vessel. His solution was very simple; by bending the machine through a 180 degree twist, forming a figure-eight instead of a donut, the plasma would alternately find itself on the inside or outside of the vessel, drifting in opposite directions. The cancellation of net drift would not be perfect, but on paper it appeared that the delay in drift rates was more than enough to allow the plasma to reach fusion conditions.
Eventually this force of three battalions, plus a battalion of local troops nominally part of the Legion but officered by local political hacks and trained separately (and loyal to Ernest Bradford, First Vice President of Hadley), allows him to dictate the outcome. The First Vice President attempts to stage a coup and threatens to kill Hadley's President Budreau, but is instead shot by Legionnaires; Falkenberg anticipated Bradford's actions. The reason for the coup is to promote a takeover by "democratic" socialist forces organizing the underclasses. Since most available resources, particularly fusion power urgently needed to build a transport net to move food and people where they are needed are already being used to feed the underclass, any takeover by the populists who have no understanding of how their society works would lead to planetary collapse.
It improved upon the work of the X-10 reactor, producing more medical isotopes, as well as allowing higher fidelity of materials research. Researchers in the Biology Division studied the effects of chemicals on mice, including petrol fumes, pesticides, and tobacco. In the late 1960s, cuts in funding led to the cancellation of plans for another particle accelerator, and the United States Atomic Energy Commission cut the breeder reactor program by two-thirds, leading to a downsizing in staff from 5000 to 3800. The inside of ORMAK, an early tokamak, was gold plated for reflectivity In the 1970s, the prospect of fusion power was strongly considered, sparking research at ORNL. A tokamak called ORMAK, made operational in 1971, was the first tokamak to achieve a plasma temperature of 20 million Kelvin.
CCFE has a broad ranging programme of activities encompassing tokamak plasma physics, technology developments for the DEMO prototype fusion power plant, the development of materials suitable for a fusion environment, engineering activities, the training of students, graduates and apprentices, and public and industry outreach activities. It also participates in a co-ordinated European programme, which is managed by the EUROfusion consortium of research institutes. This is focussed on delivering the European fusion road map, with the goal of achieving fusion electricity by 2050. CCFE is involved in a number of other international collaborations, notably the ITER tokamak being built at Cadarache in France. As well as contributing to scientific preparations for ITER with plasma physics experiments at Culham, CCFE is developing technology for the project – such as remote handling applications, specialist heating systems and instrumentation for plasma measurements (‘diagnostics’).
Approximately 3.7 protons (hydrogen nuclei), or roughly 600 million tonnes of hydrogen, are converted into helium nuclei every second releasing energy at a rate of 3.86 joules per second. The core produces almost all of the Sun's heat via fusion: the rest of the star is heated by the outward transfer of heat from the core. The energy produced by fusion in the core, except a small part carried out by neutrinos, must travel through many successive layers to the solar photosphere before it escapes into space as sunlight, or else as kinetic or thermal energy of massive particles. The energy conversion per unit time (power) of fusion in the core varies with distance from the solar center. At the center of the Sun, fusion power is estimated by models to be about 276.5 watts/m3.
Generally, lighter nuclei with a smaller number of protons and greater number of neutrons will have the greatest ratio of energy released to energy required, and the majority of fusion power research focusses on the use of deuterium and tritium, two isotopes of hydrogen. Even using these isotopes, the Coulomb barrier is large enough that the nuclei must be given great amounts of energy before they will fuse. Although there are a number of ways to do this, the simplest is to heat the gas mixture, which, according to the Maxwell–Boltzmann distribution, will result in a small number of particles with the required energy even when the gas as a whole is relatively "cool" compared to the Coulomb barrier energy. In the case of the D-T mixture, rapid fusion will occur when the gas is heated to about 100 million degrees.
A fusor, exhibiting nuclear fusion in star mode Inertial electrostatic confinement, or IEC, is a class of fusion power devices that use electric fields to confine the plasma rather than the more common approach using magnetic fields found in magnetic fusion energy (MFE) designs. Most IEC devices directly accelerate their fuel to fusion conditions, thereby avoiding energy losses seen during the longer heating stages of MFE devices. In theory, this makes them more suitable for using alternative aneutronic fusion fuels, which offer a number of major practical benefits and makes IEC devices one of the more widely studied approaches to fusion. As the negatively charged electrons and positively charged ions in the plasma move in different directions in an electric field, the field has to be arranged in some fashion so that the two particles remain close together.
Legislative definitions of renewable energy, used when determining energy projects eligible for subsidies or tax breaks, usually exclude conventional nuclear reactor designs. Physicist Bernard Cohen elucidated in 1983 that uranium dissolved in seawater, when used in Breeder reactors (which are reactors that "breed" more fissile nuclear fuel than they consume from base fertile material) is effectively inexhaustible, with the seawater bearing uranium constantly replenished by river erosion carrying more uranium into the sea, and could therefore be considered a renewable source of energy. In 1987, the World Commission on Environment and Development (WCED), an organization independent from, but created by, the United Nations, published Our Common Future, in which breeder reactors, and, when it is developed, fusion power are both classified within the same category as conventional renewable energy sources, such as solar and falling water.
Using the history of the uptake of nuclear fission reactors as a guide, these saw ITER and later DEMO as envisioning bringing online the first commercial nuclear fusion energy reactor around 2050 and depict a rapid take up of nuclear fusion energy starting after the middle of this century. However, the economic obstacles to developing traditional tokamak-based fusion power have traditionally been seen as immense, focusing on attracting sufficient investment to fund iterations of prototype tokamak reactors. More recent scenarios see innovations in computing and material sciences leading to the possibility of developing national or cost-sharing 'Fusion Pilot Plants' along a diversity of technology pathways, such as the UK Spherical Tokamak for Energy Production, within the 2030-2040 timeframe. This suggests the possibility of compact reactor technology reaching commercialization potential via a power-plant fleet approach soon afterwards.
During the time that AESD was active, the Large site also housed the Westinghouse Fusion Power Systems Department (FPSD), which had a role in development and startup of the Tokamak Reactor at the Princeton Plasma Physics Laboratory (PPPL) in 1982. Along with the Advanced Coal Conversion Department (ACCD) and Advanced Reactors Division (ARD), AESD and FPSD constituted the Company's Advanced Power Systems Business Unit (APSBU), which was based at the Company's Waltz Mill Site in Madison, Pennsylvania, along I-70 a few miles west of the New Stanton interchange of the Pennsylvania Turnpike (I-76). ACCD operated a coal gasification process demonstration unit (PDU), which was funded by DoE in the early 1970s, and conducted related research projects. ARD had the development contract for the planned Liquid Metal Fast Breeder Reactor (LMFBR) project at Clinch River, Tennessee, near the Oak Ridge National Laboratory.
Proponents believe that much of the ITER criticism is misleading and inaccurate, in particular the allegations of the experiment's "inherent danger". The stated goals for a commercial fusion power station design are that the amount of radioactive waste produced should be hundreds of times less than that of a fission reactor, and that it should produce no long-lived radioactive waste, and that it is impossible for any such reactor to undergo a large-scale runaway chain reaction. A direct contact of the plasma with ITER inner walls would contaminate it, causing it to cool immediately and stop the fusion process. In addition, the amount of fuel contained in a fusion reactor chamber (one half gram of deuterium/tritium fuel) is only sufficient to sustain the fusion burn pulse from minutes up to an hour at most, whereas a fission reactor usually contains several years' worth of fuel.
Thomson passed his concepts on to Stan Cousins and Alan Ware, who assembled a linear pinch device using old radar equipment, and started operations in 1947. Follow-on experiments used large banks of capacitors to store energy that was quickly dumped into the plasma through a solenoid wrapped around a short tube. These experiments demonstrated a number of dynamic instabilities that caused the plasma to break up and hit the walls of the tube long before it was compressed or heated enough to reach the required fusion conditions. After a short time in Chicago, Tuck was hired by Los Alamos to work on the "Super" project (the hydrogen bomb), where he was put on the task of calculating the nuclear cross section of the deuterium-tritium fusion reaction. This work continued to pique his interest in fusion power, and he spent some time through 1951 considering the problem.
The international nuclear fusion project International Thermonuclear Experimental Reactor (ITER) is constructing the world's largest and most advanced experimental tokamak nuclear fusion reactor in the south of France. A collaboration between the European Union (EU), India, Japan, China, Russia, South Korea and the United States, the project aims to make a transition from experimental studies of plasma physics to electricity-producing fusion power plants. In 2005, Greenpeace International issued a press statement criticizing government funding of the ITER, believing the money should have been diverted to renewable energy sources and claiming that fusion energy would result in nuclear waste and nuclear weapons proliferation issues. A French association including about 700 anti-nuclear groups, Sortir du nucléaire (Get Out of Nuclear Energy), claimed that ITER was a hazard because scientists did not yet know how to manipulate the high-energy deuterium and tritium hydrogen isotopes used in the fusion process.
Interior of Alcator C-Mod showing the molybdenum tiles used as first wall material Interior of Tokamak a configuration variable showing the graphite tiles used as first wall material In nuclear fusion power research, the plasma-facing material (or materials) (PFM) is any material used to construct the plasma-facing components (PFC), those components exposed to the plasma within which nuclear fusion occurs, and particularly the material used for the lining the first wall or divertor region of the reactor vessel. Plasma-facing materials for fusion reactor designs must support the overall steps for energy generation, these include: #Generating heat through fusion, #Capturing heat in the first wall, #Transferring heat at a faster rate than capturing heat. #Generating electricity. In addition PFMs have to operate over the lifetime of a fusion reactor vessel by handling the harsh environmental conditions, such as: # Ion bombardment causing physical and chemical sputtering and therefore erosion.
In the future, the world is expected to exit the "fossil fuel age", and perhaps the "nuclear energy age", and enter the "renewable-energy age" or even further into the "fusion power age", if and whenever these technologies become economically sustainable.Future energy development Being a region in the sunny tropical belt, the Indian subcontinent could greatly benefit from a renewable energy trend, as it has the ideal combination of both - high solar insolation and a big consumer base density. For example, considering the costs of energy consumed for temperature control (a major factor influencing a region's energy intensity) and the fact that - cooling load requirements, unlike heating, are roughly in phase with the sun's intensity, cooling from the excessive solar radiation could make great energetic (and hence economic) sense in the subcontinent, whenever the required technology becomes competitively cheaper.Solar Cooling German report India also has 25% of the world's thorium resources.
A pulse-forming network for an Nd:YAG laser rangefinder The Shiva Star device at Air Force Research Laboratory, USA, which generates pulsed power for high- energy fusion power experiments. Each of the 6 radial arms is a pulse-forming line delivering a pulse of energy to the center, whose capacitors store a total of 10 MJ of energy and can create microsecond pulses of 120 kV and 6 million amperes. A pulse-forming network (PFN) is an electric circuit that accumulates electrical energy over a comparatively long time, and then releases the stored energy in the form of a relatively square pulse of comparatively brief duration for various pulsed power applications. In a PFN, energy storage components such as capacitors, inductors or transmission lines are charged by means of a high-voltage power source, then rapidly discharged into a load through a high-voltage switch, such as a spark gap or hydrogen thyratron.
To make experiments under reactor-like conditions possible, essential plasma properties, particularly the plasma density and pressure and the wall load, have been adapted in ASDEX Upgrade to the conditions that will be present in a future fusion power plant. ASDEX Upgrade is, compared to other international tokamaks, a midsize tokamak experiment. It began operation in 1991 and it succeeds the ASDEX experiment, which was in operation from 1980 until 1990. One innovative feature of the ASDEX Upgrade experiment is its all-tungsten first wall; tungsten is a good choice for the first wall of a tokamak because of its very high melting point (over 3000 degrees Celsius) which enables it to stand up to the very high heat fluxes emanating from the hot plasma at the heart of the tokamak; however there are also problems associated with a tungsten first wall, such as tungsten's tendency to ionise at high temperatures, "polluting" the plasma and diluting the deuterium-tritium fuel mix.
Given the enormous potential of fusion to transform the world's energy industry and more recently to manage climate change, fusion science and the development of ITER have traditionally been seen as an integral part of long-term peace-building science diplomacy, particularly during the Cold War and immediate post-Cold War periods. However, the recent technological developments, the emergence of a private sector fusion industry and so the potential for prototype commercial fusion reactors within the next two decades has raised increasing concerns related to fusion intellectual property, international regulatory administration, and global leadership; the equitable global socioeconomic development of fusion power, and the potential for the weaponization of fusion energy, with serious implications for geopolitical stability. Developments in September and October 2020 have led to fusion being described as a "new space race". On 24 September, the United States House of Representatives approved a fusion energy research and commercialization program in H.R. 4447, the Clean Economy Jobs and Innovation Act.
This can be seen as a shortcut to viable fusion power until more efficient pure fusion technologies can be developed, or as an end in itself to generate power, and also consume existing stockpiles of nuclear fissionables and waste products. In the LIFE project at the Lawrence Livermore National Laboratory LLNL, using technology developed at the National Ignition Facility, the goal is to use fuel pellets of deuterium and tritium surrounded by a fissionable blanket to produce energy sufficiently greater than the input (laser) energy for electrical power generation. The principle involved is to induce inertial confinement fusion (ICF) in the fuel pellet which acts as a highly concentrated point source of neutrons which in turn converts and fissions the outer fissionable blanket. In parallel with the ICF approach, the University of Texas at Austin is developing a system based on the tokamak fusion reactor, optimising for nuclear waste disposal versus power generation.
Royce strategy currently focuses on research in five areas: # Low carbon power: new modes of energy generation, energy storage, and efficient energy use – from hydrogen to fusion power and energy-efficient devices # Infrastructure and mobility: efficient housing, clean transport, and transforming foundation industries for clean manufacturing # Digital and Communications: low-loss digital processes quantum technologies for computing, sensors, and data storage # Circular economy: rethinking the way we use plastic and engage with waste streams, developing truly degradable materials # Health and wellbeing: reducing carbon emissions and enabling clean water production, delivering personalised medicine, and supporting the ageing population. In September 2020, Royce published five technology roadmaps to "set out how materials science can be harnessed to deliver net-zero targets". These roadmaps were the product of a collaboration with the Institute of Physics and the Institute for Manufacturing, convening the UK's academic and industrial materials research communities to explore how novel materials and processes can contribute to more sustainable, affordable, and reliable energy production. The roadmaps cover photovoltaics, hydrogen, thermoelectrics, calorics, and low-loss electronics.

The Rutherford Appleton Laboratory and Diamond Light Source (built by the Wellcome Trust) are on the Harwell Science and Innovation Campus in Chilton and East Hendred. Harwell has an office of Telespazio VEGA UK (satellites) and the UK's base of the European Space Agency (ESA), with the European Centre for Space Applications and Telecommunications and the UK's Satellite Applications Catapult; Rutherford Appleton also has the Central Laser Facility, the UK's site of research into inertial confinement fusion power from the HiPER project. The science cluster is known as Science Vale UK. In Rotherfield Peppard, near Sonning Common, is the Johnson Matthey Technology Centre, which research fuel cells (with platinum supplied by Anglo American Platinum, the world's largest producer). Stuart Turner (pumps) is at Henley-on-Thames, with Ella's Kitchen. Countax UK, off the A329 at Great Haseley (nearer to Great Milton), manufactures Britain's best-selling garden tractors, and distributes ECHO (Japanese) power tools; to the south off the B480, Martin-Baker test ejector seats at Martin Baker Aerospace Chalgrove.
Some current research projects are focused on neutron-free fusion power, in which hydrogen and boron are heated to over 1 billion degrees, though technical and economic barriers still exist. In its October 2009 peak oil report, the Government- supported UK Energy Research Centre warned of the risk that 'rising oil prices will encourage the rapid development of carbon-intensive alternatives which will make it difficult or impossible to prevent dangerous climate changeUKERC Report Finds ‘Significant Risk’ of Oil Production Peaking in Ten Years , October 08, 2009, UK Energy Research Centre and stated that 'early investment in low-carbon alternatives to conventional oil is of considerable importance' in avoiding this scenario.Global Oil Depletion: An assessment of the evidence for a near-term peak in global oil production , page xi, August 2009, published October 08, 2009, UK Energy Research Centre, Iceland was the first country to suggest transitioning to 100% renewable energy, using hydrogen for vehicles and its fishing fleet, in 1998, but the actual progress has been very limited.
In the year 2061, the aging Sun is about to turn into a red giant and threaten to engulf the Earth's orbit within 300 years, forcing the nations of the world to consolidate into the United Earth Government to initiate a project to migrate the earth out of the Solar System to the Alpha Centauri system 4.2 light-years away, in order to preserve further human civilization. Enormous planetary thrusters running on fusion power, known as the Earth Engines, are built across the planet to propel the Earth. Human population is reduced severely due to catastrophic tsunamis that occur after the Earth's rotation is made to stop, and later as the planet moves away from the Sun, much of the surface is frozen, forcing the remaining humans to live in vast underground cities built adjacent to the engines. At the beginning of the film, the Chinese astronaut Liu Peiqiang promises to his 4-year-old son Liu Qi of his eventual return, before going to his mission to a pathfinder space station that will help navigate the Earth on its interstellar journey, and entrusts the guardianship of his son over to his father-in-law Han Zi'ang.
The Chinese Lunar Exploration Program (CLEP; ), also known as the Chang'e Project () after the Chinese moon goddess Chang'e, is an ongoing series of robotic Moon missions by the China National Space Administration (CNSA). The program incorporates lunar orbiters, landers, rovers and sample return spacecraft, launched using Long March rockets. Launches and flights are monitored by a Telemetry, Tracking, and Command (TT&C;) system, which uses radio antennas in Beijing and antennas in Kunming, Shanghai, and Ürümqi to form a VLBI antenna. “嫦娥奔月”地面主干工程基本完成 云南天文台巨型射电追踪望远镜年底投入使用 巨型望远镜送“嫦娥”飞月- 望远镜,嫦娥-北方网-科技无限 A proprietary ground application system is responsible for downlink data reception. Ouyang Ziyuan, a geologist and chemical cosmologist, was among the first to advocate the exploitation not only of known lunar reserves of metals such as titanium, but also of helium-3, an ideal fuel for future nuclear fusion power plants.
Matterhorn ultimately ended its involvement in the bomb field in 1954, becoming entirely devoted to the fusion power field. In 1958, this magnetic fusion research was declassified following the 1955 United Nations International Conference on the Peaceful Uses of Atomic Energy. This generated an influx of graduate students eager to learn the "new" physics, which in turn influenced the lab to concentrate more on basic research.Bromberg, Joan Lisa (1982) Fusion: Science, Politics, and the Invention of a New Energy Source MIT Press, Cambridge, Massachusetts, p. 97, The early figure-8 stellarators included : Model-A, Model-B, Model-B2, Model-B3. Model-B64 was a square with round corners, and Model-B65 was a racetrack configuration. The last and most powerful stellarator at this time was the 'racetrack' Model C (operating from 1961 to 1969). The Model C was reconfigured as a tokamak in 1969, becoming the Symmetric Tokamak (ST). In the 1970s research at the PPPL refocused on the Russian tokamak design when it became evident that it was a more satisfactory containment design than the stellarator. In May 1972 the Adiabatic Toroidal Compressor (ATC) began operation. The Princeton Large Torus, a tokamak, operated from 1975. By 1982, the PPPL under the direction of Harold Furth had the Tokamak Fusion Test Reactor (TFTR) online, which operated until 1997.
