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.
