fast breeder reactor

[′fast ′brēd·ər rē‚ak·tər]
(nucleonics)
A type of fast reactor using highly enriched fuel in the core, fertile material in the blanket, and a liquid-metal coolant, such as sodium; high-speed neutrons fission the fuel in the compact core, and the excess neutrons convert fertile material to fissionable isotopes; the breeding ratio is 1.0 or larger. Abbreviated FBR.

The government's Japan Atomic Energy Commission was apologetic, suggesting that no checks were imposed on controlling costs for the development of the fast breeder reactor.
"When the 500 mega watt Prototech Fast Breeder Reactor gets commissioned by year 2010 or 2011, it would be the second largest.
In a recent interview with Kyodo News, JAEA President Atsuyuki Suzuki said the plan to build a demonstration fast breeder reactor and subsequently a commercial one after Monju ''will find it hard to be understood by the public.''
The center under the atomic energy agency is in charge of promoting research and development of Monju and related technologies aimed at completing the fast breeder reactor nuclear cycle.
An alarm system at the Monju prototype fast breeder reactor in Tsuruga, Fukui Prefecture, was triggered Friday after a glitch caused a detector to falsely detect a sodium coolant leak, the Japan Atomic Energy Agency said.
The agency plans to base the next-generation nuclear reactor on the existing light water type, as a program has been effectively stalled for the development of a fast breeder reactor that could generate electricity while producing more fuel than it consumes, they said.
But energy demand tapered off with slower economic growth in Japan, and the development of fast-breeder reactors stopped when the Monju Fast Breeder reactor in Fukui Prefecture had to be shut down after a serious accident in December 1995.
