A fissionable nuclide that can be induced to fission with low-energy thermal neutrons with a high probability is referred to as fissile. Fissionable materials include also those (such as uranium-238 ) for which fission can be induced only by high-energy neutrons. Meer weergeven In nuclear engineering, fissile material is material capable of sustaining a nuclear fission chain reaction. By definition, fissile material can sustain a chain reaction with neutrons of thermal energy. The predominant … Meer weergeven To be a useful fuel for nuclear fission chain reactions, the material must: • Be in the region of the binding energy curve where a fission chain reaction is possible … Meer weergeven • Fertile material • Fission product • Special nuclear material Meer weergeven According to the Ronen fissile rule, for a heavy element with 90 ≤ Z ≤ 100, its isotopes with 2 × Z − N = 43 ± 2, with few exceptions, are fissile (where N = number of Meer weergeven In general, most actinide isotopes with an odd neutron number are fissile. Most nuclear fuels have an odd atomic mass number (A = Z + N = the total number of nucleons), and an even atomic number Z. This implies an odd number of neutrons.

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%. 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).
