fast breeder reactor notes

In this context India has successfully established the world’s first Fast Breeder Test Reactor at Kalpakkam. Before publishing your articles on this site, please read the following pages: 1. It Therefore any further nuclear power generation is possible only with imported uranium or imported reactors or by indigenous development of FBR/Thorium cycle reactors. It No moderators are used as high energy neutrons are more efficient at transmuting Uranium into Plutonium. 3. The 2nd generation reactors of India which are under development are Fast Breeder Reactors. 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 largest nuclear power plant with a fast breeder reactor is the Superphenix in France, which started operation in 1986. 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. A Breeder reactor which makes use of fast moving neutrons to bring about the nuclear chain reaction is called Fast Breeder Reactors. 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. They generate electricity and build up fuel inventory. Ans: c. 35. A breeder reactor is a nuclear reactor that generates more fissile material than it consumes. 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. properties at high temperature and low pressure. 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. In this 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. Restart has been repeatedly delayed, and, as of the end of 2009, the reactor was still shut down. Fast 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. development efforts in the fast breeder reactor technology will have to be In this reactor no moderator is used.

Breeder reactor The reactors which are designed so that breeding will take place is known as breeder reactor. Image Curtsey: upload.wikimedia.org/wikipedia/commons/4/46/LMFBR_schematics2.svg. fast breeder reactor becomes inescapable in view of the massive reserves of 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. thorium and the finite limits of its uranium resources. It used a Na-K eutectic alloy that was liquid at room temperature as a coolant. It uses chiefly uranium oxide fuel, enriched to 17, 21 & 26%, with some MOX in recent years. Cut-Away View of a Pool-Type Fast Breeder Reactor (Phenix). Disclaimer 9. stepped up considerably if nuclear power generation is to make any impact on A breeder reactor is essentially a particular configuration of afast reactor. Figure shows a fast breeder reactor system. 4. tubes of intermediate heat exchange transfers its heat to secondary coolant 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. The research and 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). Abstract. International restrictions on the import of uranium and nuclear reactor technology have also made the development of FBR/thorium cycle reactor a necessity for India. Ans: e. 34. The metals which can accomplish this are sodium and lithium, with sodium being the most abundant and most commonly used. Advantages and Disadvantages of Nuclear Power Plant, Construction and working principle of Boiling Water Reactor (BWR), Heavy Water Cooled Reactor (HWR) (or) CANDU, Advantages and disadvantages of HWR (or) CANDU type Reactor, Safety Measures carried out in Nuclear Power Plant, Important Questions and Answers: Diesel,Gas Tubine and Combined Cycle Power Plants, Open and closed cycle gas turbine power plant, Working of gas turbine cycle with Regenerator. Thus this reactor is important because it breeds fissionable material Fast breeder reactors. does not react on any of the structural materials used in primary circuits.
