WebAnswer (1 of 3): I have to interpret your question to mean: “When does a nuclear fission reaction occur without being induced by a neutron?” And, the answer to that is, of course, in spontaneous fission (SF). Several large neutron-rich radioisotopes can undergo SF. The known elements most susce... WebThe number of fissile isotope atoms generated per fission event is known as the breeding ratio [5]. A breeding ratio of greater than unity implies that for every fission reaction, more than one fissile atom can be generated, and the fuel can be bred from non-fissile material. Nuclear reactors are being developed to make use of this to breed ...
