fast breeder reactor notes

The development of Breeder technology will confer upon India self-reliance in the field of nuclear energy where India would be able to convert thorium into U-233 and then subsequently use it to operate nuclear reactors. Breeder reactors are capable of producing more fissile material than they consume during the fission chain reaction (by converting fertile U-238 to Pu-239, or Th-232 to U-233). TOS 7. 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. properties at high temperature and low pressure. In this reaction. development efforts in the fast breeder reactor technology will have to be A Nuclear Reactor that produces (Breeds) the some kind of fissile material as it burns is called breeder reactor. Image Guidelines 5. A Nuclear Reactor that produces (Breeds) the some kind of fissile material as it burns is called breeder reactor. : A fast breeder reactor (FBR) breeds more fuel than it consumes that is it produces more plutonium than it consumes while generating power. Construction of the only other commercial fast breeder reactor in the U.S., the Clinch River plant in Tennessee, was halted in 1983 when Congress cut funding. The reactor uses a plutonium-uranium mixed carbide fuel and liquid sodium as a coolant. Breeder reactor The reactors which are designed so that breeding will take place is known as breeder reactor. France is the only country in the world ever to operate a commercial scale (1,200 MWe) sodium cooled, plutonium fuelled fast breeder reactor, the Superphénix at Creys-Malville. A breeder reactor is a nuclear reactor that generates more fissile material than it consumes. Fast reactors generally have an excess of neutrons (due to low parasitic absorbtion), the neutrons given off by fission reactions can “breed” more fuel from otherwise non-fissionable isotopes or can be used for another purposes (e.g.transmutation of spent nuclear fuel). It has very low absorption For India which already is fast This is considered an important milestone in breeder reactor technology. circuits. The fissionable fuel core is surrounded by a blanket of fertile material (U-238 or Th- 232). Ans: c. 35. It Report a Violation, Useful Essay on Nuclear Power (390 Words), Nuclear Energy: Essay on Nuclear Energy (548 Words), The Causes and Consequences of Degeneration of Bio-Diversity. On June 26, 2014, the 60th anniversary of the start of the 5 MWe Obninsk reactor that was the first reactor in the world to routinely supply electricity to a commercial power grid, Russia started up the latest in a series of sodium-cooled fast reactors, the BN-800. ii) It possesses good heat transfer Introduction . Coolants A promising type of fast breeder reactors is the Liquid Metal Fast Breeder Reactor (LMFBR) in which molten liquid Sodium acts as a coolant for heat transfer. iii)            3.

A brief description of reactors of the following types-Pressurized water reactor, Boiling water reactor, Sodium graphite reactor, Fast Breeder reactor, Homogeneous graphite reactor, and gas-cooled reactor, Radiation hazards, Shielding, Radioactive waste disposal. The known source of 60,000 tons of natural uranium deposits with only 0.7% being fissile U-235 can at best generate about 15000 MW power for over 20 year period. Fast Breeder Reactors: An Engineering Introduction is an introductory text to fast breeder reactors and covers topics ranging from reactor physics and design to engineering and safety considerations. The first unclear power plant in India is located at (a) Kota (b) Kalapakkam (c) Tarapur (d) Baraeilly (e) Kerala. Study Material, Lecturing Notes, Assignment, Reference, Wiki description explanation, brief detail. Disclaimer 9. Based on successful operation of FBTR India is developing at present the world’s first Prototype Fast Breeder Reactor with the capacity of 500 MW at Kalpakkam. properties at high temperature and low pressure. Reactor fuels, coolant circuits, steam plants, and control systems are also discussed. • A fast breeder reactor can convert Uranium-238 into Plutonium-239 at a rate faster than it consumes its fuel (mixture of U-235 plus Pu-239) • By repeated recycling of the fuel, it should be realistically possible to exploit 50% of the fuel value of the uranium feed • This means that fast reactors could extend the does not react on any of the structural materials used in primary circuits. cross-sectional area. France is the only country in the world ever to operate a commercial scale (1,200 MWe) sodium cooled, plutonium fuelled fast breeder reactor, the Superphénix at Creys-Malville. Breeder reactors achieve this because their neutron economy is high enough to create more fissile fuel than they use, by irradiation of a fertile material, such as uranium-238 or thorium-232 that is loaded into the reactor along with fissile fuel. The Russian BN-600 fast breeder reactor – Beloyarsk unit 3 of 600 MWe gross, 560 MWe net – has been supplying electricity to the grid since 1980 and is said to have the best operating and production record of all Russia's nuclear power units. Its thermal power is 3000 MW, while the electrical power is 1180 MW (this corresponds to an efficiency of 39%). Figure 1. Privacy Policy 8. The breeder reactor is especially attractive in India, which hopes to develop a large domestic nuclear energy program even though it has primarily poor quality uranium ore that is expensive to mine. Utilization of thorium fuel in fast breeder reactors has a distinct advantage, namely the reduction in the positive sodium void coefficient, which has very favorable implications for the licensing of the liquid metal fast breeder reactors (LMFBRs). Figure shows a fast breeder reactor system. The fast moving neutrons liberated due to Main fast breeder reactor types and their design parameters There are two basic designs for sodium-cooled fast breeders: the pool (integrated) layout and the loop type In the pool layout, the reactor vessel contains not only the core, but also a number of other components.
