WebFissile materials are a subset of fissionable materials. Fissionable material consists of isotopes that are capable of undergoing nuclear fission after capturing either fast neutron ( high energy neutron – let say >1 MeV) or thermal neutron (low energy neutron – let say 0.025 eV). Typical fissionable materials: 238U, 240Pu, but also 235U ...
