"WebThe critical fissile materials that can sustain an explosive chain reaction are plutonium (of almost any isotopic composition) and HEU (i.e., uranium enriched in the isotope U-235). Natural uranium contains approximately 0.7% U-235 and 99.3% U-238. Practically, uranium enriched to less than 20% U-235 cannot be used for weapons, and so-called ... " - Fissile and fertile material

Fissile and fertile material

A fast-neutron reactor, meaning one with little or no neutron moderator and hence utilising fast neutrons, can be configured as a breeder reactor, producing more fissile material than it consumes, using fertile material in a blanket around the core, or contained in special fuel rods. Since plutonium-238, plutonium-240 and plutonium-242 are fertile, accumulation of these and other nonfissile isotopes is less of a problem than in thermal reactors, which cannot burn them efficien… Webquantity of the original fissile material, a significant quantity of plutonium including fissile PU-239 and Pu-241 and fertile Pu-240.
