Some fast breeder reactors can generate up to 30 percent more fuel than they use. A fast breeder reactor uses following as initial fuel: ( ) (A)highly-enriched uranium (B) plutonium (C) 238U (D) 235U (E) natural uranium There is renewed interest in fast reactors due to their ability to fission actinides, including those which may be recovered from ordinary reactor used fuel. So then- both types of breeder reactors, the Liquid Metal Fast Breeder and the Molten Salt Breeder, can avoid the cost and complexity associated with … Which among the following is the fuel used in fast breeder test reactor at Kalpakkam? Fast breeder reactors (FBRs) are essentially a more powerful version of FNRs in that they produce more plutonium than they consume. The core uses closely packed fuel elements containing a high percentage of fissionable isotopes and generates most of the heat of the reactor from fast fissions in the fuel contained in the core. The core of a breeder reactor contains fissile uranium and plutonium, atoms that split easily and release energy as heat and radiation. The fast breeder reactor (FBR) is a fast neutron reactor designed to breed fuel by producing more fissile material than it consumes. Answer: 4) 235 U. 56 D. U ₂₃₅. 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). A. Boiling water. C. Thorium. Technically it can be done, in fact a fuel cycle called DUPIC (Direct Use of Spent PWR fu in CANDU) was developed by the (then) AECL in the 1990s. A fast breeder reactor uses following as fuel. These are available in two types namely the Magnox and the AGR (advanced gas-cooled reactor). C. Pressurised water. Answer & Solution Discuss in Board Save for Later. In Japan, an experimental fast-breeder reactor "Joyo" was first developed by the Japan Atomic Energy Agency (JAEA, former Power Reactor & Nuclear Fuel Development Corporation). D. All of the above. Conventional reactors use uranium as fuel and produce some plutonium Breeders produce much more Plutonium, which can be separated and reused as fuel. This is a nuclear reactor without electric generating facilities, and started operation in 1977 with the aim of accumulating technical experiences of the fast-breeder reactor. The blanket absorbs the excess neutrons produced by the core. The power density in a fast breeder reactor is considerably higher than in normal reactors. PRS14-L1 A fast breeder reactor uses following as initial fuel (1) highly-enriched uranium (2) plutonium (3) 238 U (4) 235 U (5) natural uranium. The Japanese Atomic Energy Agency (JAEA) disclosed details of an accident that happened on August 26, 2010 at the Monju fast breeder reactor (here is the original JAEA letter).As described in the press, the accident involved a 3-tonne "fuel-replacement device" falling into the reactor vessel when being removed after a scheduled fuel replacement operation. These reactors use C02 like the coolant & graphite like the moderator. A breeder reactor is essentially a particular configuration of a fast reactor. FBRs usually use a mixed oxide fuel core of up to 20% plutonium dioxide (PuO2) and at least 80% uranium dioxide (UO2). These reactors are used only in the UK. They take nuclear material that makes for poor fuel on its own and through the absorption of neutrons, make it into something more suitable as a fuel. The fast breeder reactor uses the following moderator (a) demineralised water (b) carbon dioxide (c) heavy water (d) graphite (e) no moderator is used. Fast . The first unclear power plant in India is located at (a) Kota (b) Kalapakkam (c) Tarapur (d) Baraeilly (e) Kerala. 44 Table 3.4 Reliability of breeder reactors. As a fuel, it uses natural uranium because, in a pressurized water reactor, the coolant can be used for boiling normal water in a different loop. C. Thorium. A fast breeder reactor is a type of nuclear reactor that uses nuclear fission to create plutonium 239 atoms as a by-product of the splitting of uranium 235 atoms. Example: avoid using "grt" instead of "great". Gas-cooled Reactors. Plutonium. Required fields are marked * Comment. 40 Table 3.2 CDA work energy calculations. These simulated fuel pellets and the stainless steel fuel pin illustrate the size of actual fast breeder fuel pellets. The most common breeding reaction is that of plutonium-239 from non-fissionable uranium-238. Your email address will not be published. B. Therefore, liquid sodium, which is an efficient coolant and does not moderate neutrons, is used to take away heat produced in the core. Under appropriate operating conditions, the neutrons given off by fission reactions can "breed" more fuel from otherwise non-fissionable isotopes. The liquid-metal fast breeder reactor (LMFBR) concept relies on plutonium fuel and 238 U (depleted uranium) for breeding of additional plutonium in amounts that exceed what is “burned” for power production. This ability to create, or "breed," additional fuel accounts for the name given to these types of reactors. Reply. Fast Breeder Reactor. D. U ₂₃₅. A. Enriched uranium. A fast breeder reactor uses following as fuel. … Fast breeder reactors which use uranium-238 as fuel and thermal breeder reactors which use thorium-232 as fuel. PAKMCQS MENU. 44 apan’s Plutonium Breeder Reactor and its Fuel CycleJ Table 4.1 Commercialization in Japan. A. Enriched uranium. B. Our country has large deposits of thorium resource but a limited one of uranium resource. FBRs usually use a mixed-oxide fuel core of up to 20% plutonium dioxide (PuO 2) and at least 80% uranium dioxide (UO 2). A fast breeder reactor uses following as fuel_____? Nuclear Power Plants Nuclear Power Plants. A fast breeder reactor is one which breeds more material for a nuclear fission reaction than it consumes. PLEASE COMMENT BELOW WITH CORRECT ANSWER AND ITS DETAIL EXPLANATION. Creating extra fuel in nuclear reactors, however, is not without … For this reason, no moderator is required to thermalize the fast neutrons. A fast breeder reactor uses following as fuel_____? Since plutonium does not exist naturally, it must be produced initially in a uranium fuel cycle. Name * Email * Website. The fast breeder reactor uses the following moderator (a) demineralised water (b) carbon dioxide (c) heavy water (d) graphite (e) no moderator is used. The fast neutron environment minimises neutron capture reactions and maximises fissions in actinides. Submit. 50. Superheated steam is generated in following reactor. 49. While fast neutrons are less likely to be absorbed by uranium-235 or plutonium-239 than thermal neutrons, the highly enriched fuel used in fast breeder reactors allows for a self-sustaining nuclear chain reaction.

English Mcqs; … 41 Table 3.3 Cost of electricity. 34. Just one of these pellets in a fast breeder reactor will produce the energy equivalent of any of the following: three tons of coal, 12 barrels of oil, 500 gallons of gasoline, or 75K cubic feet of natural gas. So the reactor starts on uranium fuel and each time the fuel is replaced it transitions gradually to plutonium fuel. Share this question with your friends. Water would have absorbed too many precious neutrons, and … Mcq Added by: Muhammad Bilal Khattak. Apart from a fast-breeder reactor, the main alternative is to blend the plutonium with other fuel to create a mixed-oxide fuel (mox) that will burn in conventional nuclear power plants. Yes and no. Correct Answer : D. Comment. Fast breeders do not require moderation since 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. With fuel enriched to 15 or 20% in uranium-235 or plutonium, it become no longer necessary to "thermalize "neutrons as in the common pressurized water reactors, for example. 2 ia and Fast Breeder ReactorsInd Table 3.1 Containment design specifications. 2 Explanation In a fast breeder reactor, once started with a small amount of U 235 , the generated fast neutrons are captured by U 238 .
