|
This, among other things, covers "boosted fission devices," which are mostly fission, but use hydrogen isotopes to juice things up.
|
|
Thermonuclear weapons typically use a fission explosion to create a fusion reaction, which is far more powerful than a fission reaction.
|
|
Constructed from elements such as silver and iridium, the control rods absorb neutrons released during fission and slow down the rate of fission.

|
It's possible that the warhead could be a relatively lower-yield fission device, a boosted-fission device, or a full-on staged nuclear weapon.

|
|
This process of fusion releases even more energy per unit of mass than fission does, and the energy released from the fusion reaction also feeds back into the fission reaction, increasing its output.

The reactor created more steam than it could vent, the fission reactions churned on, and the pressure from the steam exploded, rupturing fuel lines and exploding out the roof of the reactor.
|
|
Unlike the nuclear fission that powers conventional reactors today, in which atoms are split apart, fusion power is generated when you smoosh two smaller atoms into a larger one inside a containment device.

North Korea claimed the device tested Sunday was a hydrogen bomb, a much more powerful type of nuclear weapon that uses fusion instead of fission to increase the blast yield, or destructive power.
|
|
ATOMIC BOMBS—The first nuclear weapons, developed during World War II, atomic bombs, or fission weapons, use a process by which neutrons collide with an atom's nucleus and release energy with explosive force.
|
|
Since most nuclear power plants on Earth are designed to produce hundreds of kilowatts electricity, this meant that Gibson and his colleagues would have to come up with a new fission reactor design.
|
|
Lise Meitner was one of the physicists who discovered nuclear fission, and though she received many honors in her lifetime, the 1944 Nobel Prize for that breakthrough went to her collaborator, Otto Hahn.
|
|
If successfully commercialized, fusion could provide a powerful source of clean energy without many of the drawbacks of nuclear fission (typically referred to as "nuclear energy"), such as the production of hazardous waste.
|
|
A hydrogen weapon uses an initial nuclear fission explosion to create a tremendous pulse that compresses and fuses small amounts of deuterium and tritium, kinds of hydrogen, near the heart of the bomb.
|
|
When there are enough fissile atoms close together — a quantity known as critical mass — the particles ejected by fission can strike other fissile atoms, triggering more atoms to split apart and so on.
|
|
Unlike existing fission reactors, which produce energy by splitting atoms, ITER would generate power by combining atoms, but it remains unclear whether the technology will work and whether it will eventually be commercially viable.
|
|
The process likely used by North Korea, called "boosting," involves an intermediate device that uses a hydrogen isotope to vastly increase the explosive power of an old-fashioned fission bomb, the experts told Reuters.
|
|
But some also said that although North Korea did not yet have H-bomb capability, it might be developing and preparing to test a boosted fission bomb, more powerful than a traditional nuclear weapon.
|
|
Einstein was already in the US, having fled Germany when the Nazis came to power, and learned that German scientists had discovered nuclear fission, the process of splitting an atom's nucleus to release energy.
|
|
This is why we hunt for them by nuclear reactors, where beta decay is taking place continually as the fragments leftover from fission reactions try to find a stable state to end up in.
|
|
The heat from the fission reaction is used to heat liquid sodium, which transfers this heat to eight Stirling engines that convert the heat into mechanical motion to drive electric generators and produce electricity.
|
|
Jones and Bellaiche, though mainly sticking to conventional documentary construction, throw in an interesting formal tic to visually convey the fission between how Tsemel's clients act and their portrayal in the media and culture.
|
|
Instead of a fission reactor, Phoenix employs a small-scale version of a process that some hope will one day lead to fusion reactors (and which already lies at the heart of hydrogen bombs).
|
|
A successful two-stage hydrogen bomb, which uses atomic fission to trigger a larger nuclear fusion reaction, can be between several hundred and several thousand times more powerful than the test North Korea conducted.
|
|
A company like TerraPower, which happens to be a nuclear fission company, is able to create a fourth-generation design and actually see what happens during a Richter 10 earthquake or volcano or tidal wave.
|
|
The bomb that leveled Hiroshima contained about 140 pounds of enriched uranium, but only two percent of it underwent fission (just under three pounds)–still, it produced a blast equivalent to 15 kilotons of TNT.
|
|
As with all new nuclear weapons possessors, North Korea first developed fission bombs, which are based on the process of heavy nuclei (such as uranium and plutonium) splitting into fragments, releasing large amounts of energy.
|
|
"We're using the same physical reactions — we're using fission — but almost everything else about what we're trying to do is completely different from the industry, historically," said Caroline Cochran in a telephone interview with Hyperallergic.
|
|
It's around 2025, and Abby Dixon (Sarah Habel) is a loyal engineer for the Auxilisun company, whose tri-fission engine saved the world from a fossil-fuel crisis by converting nuclear waste into usable energy.
|
|
A pure fission device is the type of bomb that the US dropped on Japan at the end of World War II. A boosted device is more complex but more efficient and can be made smaller.
|
|
Cooling towers are used to cool water that's never actually exposed to the nuclear fission process inside a reactor, so the steam that pours out of the top of them poses no risk to the environment.
|
|
If those neutrons go on to split other uranium atoms, this creates a "fission chain reaction" and when this happens millions of times, it can create a lot of heat from relatively small amounts of uranium.
|
|
In reality, most experts think the weapon was not the kind of fusion-based city-destroyer we think of when we hear "H-bomb," but rather a less dramatic nuclear weapon, called a boosted fission bomb.
|
|
It's possible North Korea has a "boosted" weapon, one that uses a small amount of fusion to boost the fission process, but is not a hydrogen bomb, but whether there was a hydrogen element isn't known.
|
|
Perhaps it isn't as surprising as it feels — a survey of scientists a decade before the Manhattan Project, asking when weaponized nuclear fission would first be achieved, might have produced such a wide range of guesses.
|
|
Whether it's nuclear fission or rocket propulsion, bioengineering or cryptography, it's the intentions of the people using a technology, not some inherent characteristic with the technology itself, that ultimately determines whether it is good or evil.
|
|
In an adaptation that biologists call fission-fusion, when coyotes come under pressure from hunters, their packs split up into lone animals and pairs, they start producing much larger litters, and they migrate into new areas.
|
