WebMar 29, 2024 · atomic bomb, also called atom bomb, weapon with great explosive power that results from the sudden release of energy upon the splitting, or fission, of the nuclei of a heavy element such as plutonium or uranium. When a neutron strikes the nucleus of an atom of the isotopes uranium-235 or plutonium-239, it causes that nucleus to split into … WebUranium-238 (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 fissile plutonium-239. 238 U …

Web236 U is neither a fissile isotope nor a fertile isotope. 236 U is fissionable only by fast neutrons. Isotope 236 U is formed in a nuclear reactor from fissile isotope 235 U. 236 U decays via alpha decay to 232 Th with a half-life of ~2.3×10 7 years. 236 U occasionally decays by spontaneous fission with a very low probability of 0.00000009%. css html vertical alignWebJun 19, 2024 · Nuclear Fuels. Nuclear fuel consists of a fissionable isotope, such as uranium-235, which must be present in sufficient quantity to provide a self-sustaining chain reaction.
