Web10 apr. 2024 · Pu-239 is normally produced by subjecting U-238 to neutrons. U-239 emits a beta, converting to Np-239, which also emits a beta, converting to Pu-239. Both those steps have relatively short half-lives, and chemical techniques can be used to separate the elements from one another. WebPlutonium-239 is one of the two fissile materials used for the production of nuclear weapons and in some nuclear reactors as a source of energy. The other fissile material is uranium-235. Plutonium-239 is virtually nonexistent in nature. It is made by bombarding uranium-238 with neutrons in a nuclear reactor. Uranium-238 is present in quantity in […]
