The beginnings ofthe Fast Breeder Project date back to 1957. Nuclear fission by fast neutrons causes the increase in neutrons generated. view of safety and thermal efficiency. The Indira Gandhi Centre for Atomic Research (IGCAR) is responsible for the design of this reactor. The breeding ratio is a measure of how much new fissile fuel a reactor is capable of producing as it runs. Fast reactors have high breeding ratios and more neutrons going around. A breeder reactor is essentially a particular configuration of afast reactor. Advanced Heavy Water Reactor (AHWR) 3. In this reactor the core containing U235 in surrounded by a blanket (a layer of fertile material placed outside the core) of fertile material U238. It is the ratio of the number of fissile atoms created with the number of fissions occurring. These have higher neutron economy for breeding fissile fuel from materials like U-238 and Th-232. About Prototype Fast Breeder Reactor (PFBR) The Kalpakkam PFBR is using uranium-238 not thorium, to breed new fissile material, in a sodium-cooled fast reactor design. Fast reactors using uranium fuel inherently create more fissile atoms per fission that uranium-fueled thermal reactors. Fast reactors using uranium fuel inherently create more fissile atoms per fission that uranium-fueled thermal reactors. Its successor, EBR-II, was used from 1963 to 1994 to test equipment and materials. The secondary coolant while flowing through the tubes
It is supposed to minimize nuclear waste. 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. It possesses good heat transfer
