breeder reactor

Quick Reference

A nuclear reactor that produces more fuel than it consumes, by bombarding isotopes of uranium and thorium with high‐energy neutrons. This converts inert (unreactive) atoms to ones that can be split (fission), which sustains the nuclear chain reaction but can be dangerous because the chain reaction is difficult to control. Also known as breeder nuclear fission reactor, or fast breeder.
