Webthus, the net energy available is 197 MeV, or roughly 200 MeV per fission. Table 2.1-1 lists the particles and the energy each particle produces per fission event. Neutron production (neutrons per fission) varies with the different fissionable isotopes and with the energy at which the fission reaction is caused to take place. Webneutrons.) If, on average, each fission leads to more than one additional fission, the chain reaction grows exponentially and releases large amounts of energy. Atomic forces …
