2.14: Nuclear Fission

Nuclear Fuels Nuclear fuel consists of a fissionable isotope, such as uranium-235, which must be present in sufficient quantity to provide a self-sustaining chain reaction. In the United States, uranium ores contain from 0.05–0.3% of the uranium oxide U 3 O 8; the uranium in the ore is about 99.3% nonfissionable U-238 with only 0.7% fissionable U-235.

Fission Chain Reaction

Fission Chain Reaction. If a slow neutron collides with a nucleus of uranium 235 U, the nucleus may disintegrate into two fission products and release 2 (sometimes 3) fast neutrons.
