The Experimental Breeder Reactor I, EBR-I, in the Idaho desert turned into a museum. Fast breeders do not require moderationsince the neutrons need to be moving fast, whereas thermal breeders make us of moderation to achieve slower-moving neutrons. Reactors known as fast neutrons or breeders reactors do not need to slow down neutrons. The plutonium-239 breeder reactor is commonly called a fast breeder reactor, and the cooling and heat transfer is done by a liquid metal. Breeder reactors can utilize nearly 100% of the energy contained in uranium and thorium ores, while the reactors currently used for nuclear power generation can use at most 1%. M    N    Many countries have long pursued fast neutron breeder reactors, which create more fissile fuel than they consume, because of the limited availability of low-cost uranium used for fuel in most commercial nuclear power reactors. India’s first pressurised fast breeder reactor (PFBR), being set up at the Madras Atomic Power Station at Kalpakkam in Tamil Nadu state, is likely to be commissioned in October 2022, according to the country’s Atomic Energy Minister Jitendra Singh. The plutonium of spent MOX fuel, currently in storage, could also be blended to 15% with depleted uranium. In the early 21st century, all large power plants using fast breeder reactors employed liquid-metal fast breeder reactors, which convert uranium-238 into the fissionable isotope plutonium-239 by means of artificial radioactive decay. Plutonium-239 is extremely toxic; the half-life of the material is extremely long — about 24,000 years. It was stopped in 1997 more for political than technical reasons. A breeder reactor is a nuclear fission reactor that creates more usable fuel (plutonium-239) than it consumes. C    Such reactors are called "breeders". 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. In breeder reactor: Fast breeder reactors …using fast breeder reactors employed liquid-metal fast breeder reactors, which convert uranium-238 into the fissionable isotope plutonium-239 by means of artificial radioactive decay. The most common breeding reaction is an absorbtion reaction on uranium-238, where a plutoniu… S    They would have the ability to destroy plutonium and would additionally be safe. W    In this reactor the core containing U 235 in surrounded by a blanket (a layer of fertile material placed outside the core) of fertile material U 238.In this reactor no moderator is used. Conversion ratio, break-even, breeding ratio, doubling time, and burnup This ability to create, or "breed," additional fuel accounts for the name given to these types of reactors. Fast Breeder Reactors Alan Edward Waltar, Albert Barnett Reynolds Snippet view - 1981. Breeders were initially considered attractive because of their superior fuel economy compared to light water reactors. They can reuse waste from existing reactors as fuel, until nothing is left but fission products. This process creates more fuel in the form of plutonium 239 than it uses. It is hoped that breeder reactors can replace the current generation of conventional reactors as progress in nuclear power continues. Corrosionpedia Terms:    See more.
