WebApr 10, 2024 · Uranium-235: It is the second most abundant isotope of uranium, accounting for less than 1% of natural uranium. It has 92 protons and 143 neutrons in its nucleus. Unlike uranium-238, it is fissile, which means it can sustain a nuclear chain reaction. It is used as fuel in nuclear reactors and as the primary material for nuclear weapons. WebA fissile material is one that will undergo fission when bombarded by neutrons of any energy. The isotope uranium-235 is a fissile material. A fertile material is one that will capture a neutron, and transmute by radioactive decay into a fissile material. Uranium-238 is a fertile material. Fertile isotopes may also undergo fission directly, but ... WebThe critical fissile materials that can sustain an explosive chain reaction are plutonium (of almost any isotopic composition) and HEU (i.e., uranium enriched in the isotope U-235). Natural uranium contains approximately 0.7% U-235 and 99.3% U-238. Practically, uranium enriched to less than 20% U-235 cannot be used for weapons, and so-called ... so many weapons
