Fissile material nuclear physics Britannica

WebNuclei such as 235 U that lead to fission following the thermal neutron absorption are called fissile nuclei. For heavy nuclides with an atomic number of higher than 90, most fissile isotopes meet the fissile rule: Fissile isotopes have 2 x Z – N = 43 ± 2 (example for 235U: 2 x 92 – 143 = 41) WebIn nuclear weapons, the fission energy is released all at once to produce a violent explosion. The most important fissile materials for nuclear energy and nuclear weapons are an … 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%. birch t-molding

"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.) " - List of fissile isotopes

List of fissile isotopes

WebU-235 is the only naturally occurring isotope which is thermally fissile, and it is present in natural uranium at a concentration of 0.7%. U-238 and Th-232 are the main naturally-occurring fertile isotopes. The probability that fission or any another neutron-induced reaction will occur is described by the neutron cross-section for that reaction.

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 …

WebUranium found in nature consists largely of two isotopes, uranium-235 (U-235, fissile) at 0.7 % and uranium-238 (U-238, non fissile) at 99.3 %. U-238 does not contribute directly to the fission process (though it does so indirectly by the formation of fissile isotopes of plutonium 239). WebA fissile isotope, such as uranium-235, is one that is sufficiently large and unstable to undergo such a chain reaction, as opposed to the more common and less unstable uranium-238. Ponytail fear that her raspberries have too many unstable isotopes so that her fields risk undergoing a similar fission-driven chain reaction.
