fast-breed|er reactor

fast-breed|er reactor
fast breeder, or fast-breed|er reactor «FAST BREE duhr, FAHST-»,
an atomic power plant that utilizes fast neutrons to produce its own plutonium fuel as well as generate power with almost no loss of fissionable material: »

Two different breeder systems are involved, depending on which raw material is being transmuted. The thermal breeder, employing slow neutrons, operates best on the thorium 232-uranium 233 cycle (usually called the thorium cycle). The fast breeder, employing more energetic neutrons, operates best on the uranium 238-plutonium 239 cycle (the uranium cycle) (Glenn T. Seaborg and Justin L. Bloom).

Abbr: FBR (no periods).
