WebUranium-235 is the only naturally occurring fissile nuclide. 13 Fissile nuclides undergo thermal fission stimulated by neutron capture. Thermal fission (Table 1.3) generates two or more neutrons, sufficient to sustain the nuclear chain reaction harnessed by nuclear reactors and nuclear weapons.Unlike other decay reactions (cf. Table 1.3) fission … WebCesium (Cs, atomic number 55) is an alkali metal having 40 isotopes, ranging in mass from 112 to 151. Of these, the fission product cesium-137 (half-life 30.17 years) is of greatest concern. Cesium-137 is one of the nuclides most responsible for the radioactivity of used reactor fuel and high-level waste (with the other being strontium-90).
