WebNeutron poisons are fission products that are of concern in reactors primarily because they become parasitic absorbers of neutrons and result in long-term sources of heat (so-called decay heat). Their buildup in the reactor tends to reduce the multiplication factor. Nuclear fission fragments are the fragments left after a nucleus fissions. WebIn 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 [1] energy. The predominant neutron energy may be typified by either slow neutrons (i.e., a thermal system) or fast neutrons.
