List of fissile isotopes
WebMost of the fuel mass in a reactor is U-238. This can become plutonium-239 and by successive neutron capture Pu-240, Pu-241 and Pu-242 as well as other transuranic isotopes (see information page on Plutonium). Pu-239 and Pu-241 are fissile, like U-235. (Very small quantities of Pu-236 and Pu-238 are formed similarly from U-235.) Web9 apr. 2024 · After uranium is mined, it needs to be processed to increase the concentration of the fissile isotope U-235, which is used for nuclear fission. This process is called uranium enrichment, ...

Uranium (92U) is a naturally occurring radioactive element that has no stable isotope. It has two primordial isotopes, uranium-238 and uranium-235, that have long half-lives and are found in appreciable quantity in the Earth's crust. The decay product uranium-234 is also found. Other isotopes such as uranium-233 have been produced in breeder reactors. In addition to isotopes found in nature or nuclear reactors, many isotopes with far shorter half-lives have been produce… WebArtificial isotopes 233U. 233 U belongs to the group of fissile isotopes. It is produced by radiative neutron capture in nuclear reactors containing thorium fuel. 233 U decays via alpha decay into 229 Th with a half-life of 159 200 years. 233 U occasionally decays by spontaneous fission with a very low probability of 0.000000006%.

WebTypical fissile materials: 235 U, 233 U, 239 Pu, 241 Pu. Fertile material consists of isotopes that are not fissionable by thermal neutrons but can be converted into fissile isotopes … WebFast reactors more deliberately use the uranium-238 as well as the fissile U-235 isotope used in most reactors. If they are designed to produce more plutonium than the uranium and plutonium they consume, they are called fast breeder reactors (FBRs). But many designs are net consumers of fissile material including plutonium.*
