WebQuestion: Why does U-238 not undergo fission? It’s not true that U-238 doesn’t undergo fission. It can fission into two large fragments, either spontaneously, or by absorption of a fast neutron, which is called neutron induced fission. WebThe fissioning of an atom of uranium-235 in the reactor of a nuclear power plant produces two to three neutrons, and these neutrons can be absorbed by uranium-238 to produce plutonium-239 and other isotopes. …

Uranium-238 ( U or U-238) is the most common isotope of uranium found in nature, with a relative abundance of 99%. Unlike uranium-235, it is non-fissile, which means it cannot sustain a chain reaction in a thermal-neutron reactor. However, it is fissionable by fast neutrons, and is fertile, meaning it can be transmuted to … See more In a fission nuclear reactor, uranium-238 can be used to generate plutonium-239, which itself can be used in a nuclear weapon or as a nuclear-reactor fuel supply. In a typical nuclear reactor, up to one-third of the generated … See more Most modern nuclear weapons utilize U as a "tamper" material (see nuclear weapon design).
