Fission 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 WebWhen bombarded by neutrons, certain isotopes of uranium and plutonium (and some other heavier elements) will split into atoms of lighter elements, a process known as nuclear fission. In addition to this formation of lighter atoms, on average between 2.5 and 3 free neutrons are emitted in the fission process, along with considerable energy. As a rule of …
