It relies on the absorption of neutrons by heavy nuclei, such as uranium-235 or plutonium-239. Once a neutron collides with an unstable nucleus, the fission reaction can proceed without extreme ...

Then some of the plutonium would fission, yielding energy and creating ... the uranium can be run through the reactor again & again until essentially all of it has been turned into energy.

Once detonated, the explosives condense the plutonium surrounding the case so intensely that it triggers a fission reaction. The transition from “atomic” to “thermonuclear” designation ...

Plutonium pits are hollow spheres that cause the nuclear explosion of these deadly weapons. Usually, a chemical explosion ...

Moltex, a UK-founded company developing its waste-to-fuel reactor design in Canada, has previously argued that nuclear waste ...

Heat builds rapidly, produced by the fission of uranium-235 and plutonium-239. If the chain reaction of fission and decays is allowed to go on, the heat will build up enough that the fuel rods ...
