The efficiency obtained with liquid sodium is about 42%, whereas with other coolants it is about 28%. 44 apan’s Plutonium Breeder Reactor and its Fuel CycleJ Table 4.1 Commercialization in Japan. 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. Fast . A. Boiling water. 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. 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). 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. A fast breeder reactor uses following as fuel_____? 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. 34. Gas-cooled Reactors. Since plutonium does not exist naturally, it must be produced initially in a uranium fuel cycle. Creating extra fuel in nuclear reactors, however, is not without … 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. C. Pressurised water. For this reason, no moderator is required to thermalize the fast neutrons. Reactors known as fast neutrons or breeders reactors do not need to slow down neutrons. B. 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. A fast breeder reactor uses following as fuel. 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. 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 … D. U ₂₃₅. Answer: 4) 235 U. IF YOU THINK THAT ABOVE POSTED MCQ IS WRONG. VI Plutonium Fuel Cycle. This ability to create, or "breed," additional fuel accounts for the name given to these types of reactors. Nuclear Power Plants Nuclear Power Plants. 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. This process creates more fuel in the form of plutonium 239 than it uses. 50. 2 ia and Fast Breeder ReactorsInd Table 3.1 Containment design specifications. 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. 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. Your email address will not be published. These reactors are used only in the UK. Ans: c 35. Our country has large deposits of thorium resource but a limited one of uranium resource. Please do not use chat terms. B. Correct Answer : D. Comment. The fast neutron environment minimises neutron capture reactions and maximises fissions in actinides. The core of a breeder reactor contains fissile uranium and plutonium, atoms that split easily and release energy as heat and radiation. Therefore, liquid sodium, which is an efficient coolant and does not moderate neutrons, is used to take away heat produced in the core. A fast breeder reactor uses following as fuel. Submit. The most common breeding reaction is that of plutonium-239 from non-fissionable uranium-238. Answer & Solution Discuss in Board Save for Later. Example: avoid using "grt" instead of "great". 56 Gas cooled. A. Enriched 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. Some fast breeder reactors can generate up to 30 percent more fuel than they use. It is supposed to minimize nuclear waste. Answer & Solution Discuss in Board Save for Later. The power density in a fast breeder reactor is considerably higher than in normal reactors. PLEASE COMMENT BELOW WITH CORRECT ANSWER AND ITS DETAIL EXPLANATION. Table 1.1 Major fast breeder reactors. 44 Table 3.4 Reliability of breeder reactors. So the reactor starts on uranium fuel and each time the fuel is replaced it transitions gradually to plutonium fuel. Yes and no. Fast breeder reactors which use uranium-238 as fuel and thermal breeder reactors which use thorium-232 as fuel. Under appropriate operating conditions, the neutrons given off by fission reactions can "breed" more fuel from otherwise non-fissionable isotopes. A. enriched uranium B. plutonium C. thorium D. U235 E. natrual uranium. PAKMCQS MENU. FBRs usually use a mixed-oxide fuel core of up to 20% plutonium dioxide (PuO 2) and at least 80% uranium dioxide (UO 2). These reactors use C02 like the coolant & graphite like the moderator. 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. Conventional reactors use uranium as fuel and produce some plutonium Breeders produce much more Plutonium, which can be separated and reused as fuel. Reply. A fast breeder reactor is one which breeds more material for a nuclear fission reaction than it consumes. It is the key to India''s three-stage nuclear power programme. 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. These simulated fuel pellets and the stainless steel fuel pin illustrate the size of actual fast breeder fuel pellets. A breeder reactor is a type of power reactor that operates without a moderator to slow the neutrons. Mcq Added by: Muhammad Bilal Khattak.

Which among the following is the fuel used in fast breeder test reactor at Kalpakkam? The fast breeder reactor (FBR) is a fast neutron reactor designed to breed fuel by producing more fissile material than it consumes. 40 Table 3.2 CDA work energy calculations. … Superheated steam is generated in following reactor. FBRs usually use a mixed oxide fuel core of up to 20% plutonium dioxide (PuO2) and at least 80% uranium dioxide (UO2). 49. ” admin says: 13/08/2016 at 6:17 PM . 41 Table 3.3 Cost of electricity. Fast Breeder Reactors. Answer: [C] Thorium Notes: Please note that Kamini is the only reactor in the world to use Uranium-233 type fuel, which is converted from Thorium. 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. C. Thorium. The blanket absorbs the excess neutrons produced by the core. These are available in two types namely the Magnox and the AGR (advanced gas-cooled reactor). 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.
