In contrast to most normal nuclearreactors, however, a fast reactor uses a coolant that is not an efficient moderator, such as liquid sodium, so its neutrons remain high-energy. These reactorsare called breederreactors.
People also ask
What is breeder reactor?
Breeder reactor, nuclear reactor that produces more fissionable material than it consumes to generate energy. This special type of reactor is designed to extend the nuclear fuel supply for electric power generation.
Why are fast breeder reactors used for plutonium production?
Fast neutrons are ideal for plutonium production because they are easily absorbed by U 238 to create Pu 239, and they cause less fission than thermal neutrons. Some fast breeder reactors can generate up to 30 percent more fuel than they use.
What is the difference between a conventional reactor and an experimental reactor?
Conventional reactors, in contrast, can extract less than one percent of its energy. The first experimental breeder reactor, designated EBR-1, was developed in 1951 by U.S. scientists at the National Reactor Testing Station (now called Idaho National Engineering Laboratory), near Idaho Falls, Idaho.
What is the difference between fast breeder and thermal breeder?
Fast breeders do not need moderation as neutrons need to move fast. In contrast, thermal breeders make use of moderation to reach slower-moving neutrons. The most promising breeder reactor is the Liquid Metal Fast Breeder Reactor (LMFBR), which uses liquid sodium coolant and breeds plutonium uranium-238.
