WebNatural uranium consists primarily of isotope 238 U (99.28%). Therefore the atomic mass of the uranium element is close to the atomic mass of the 238 U isotope (238.03u). ... 234 U is a non-fissile isotope, and it cannot undergo a fission reaction after absorbing a thermal neutron. 234 U belongs to the group of fertile isotopes. WebFissionable materials are a superset of fissile materials. Fissionable materials also include an isotope 238 U that can be fissioned only with high energy (>1MeV) neutron. These materials are used to fuel thermal nuclear reactors because they can sustain a nuclear fission chain reaction.. The distinction between Fissionable, Fissile, and Fertile
