Nuclear Power Plants Nuclear Power Plants. other uses for fast reactors, particularly for the control of plutonium stocks by burning them, and the treatment of radioactive wastes. 56) Coolant used in a boiling water reactor is. WNA defines a fast breeder reactor as one that produces more fissile material than it consumes. Hence the entire primary circuit including all the major components in the circuit needs to be shielded to protect the personnel handling it and the walls of the reactor from exploding. A. uses slower neutrons for fission. Ans: e; The first unclear power plant in India is located at (a) Kota (b) Kalapakkam (c) Tarapur (d) Baraeilly (e) Kerala. The most common breeding reaction is an absorbtion reaction on uranium-238, where a plutoniu… Participate in the Sanfoundry Certification contest to get free Certificate of Merit. B. uses faster neutrons for fission. A Enriched uranium . 33. Ans: c; The nuclear power plant at Tarapur has the following reactor (a) fast breeder Fast breeder reactor uses Double circuit system of coolant cycle fast reactor uses a coolant that is not an efficient moderator, such as liquid sodium, so its neutrons remain high-energy. A Boiling water . The following section consists of Chemistry Multiple Choice questions on Nuclear Power Engineering. Natural uranium as fuel and heavy water as moderator and coolant. As already mentioned, in the fast neutron spectrum, the neutron absorption cross-sections for Fe and other alloying elements are very small and hence neutron absorption is not a concern in the selection of the materials. Explanation: Fast breeder reactors do not use Thorium-232 as fuel. MCQ Mechanical Engineering 0. The stages in the programme are as follows. Breeder cores needed lots … (adsbygoogle = window.adsbygoogle || []).push({}); PakMcqs.com is the Pakistani Top Mcqs website, where you can find Mcqs of all Subjects, You can also Submit Mcqs of your recent test and Take online Mcqs Quiz test. It is feared that an explosion in the Monju breeder reactor in Japan can release 60 times the energy of the atom bomb dropped on Nagasaki in 1945.

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. Ans: c 35. "The fast breeder technology has the potential to make the production of energy from uranium 100 times more efficient than with the existing thermal reactor, reducing the amount and toxicity of radioactive waste, as well as the heat emanating from the waste, and also shortening the waste's hazardous lifetime span," says Monti. Here you will find the General Science Multiple Choice Questions Mcqs are from Biology, Chemistry, Physics and Atmospheric Studies. 3. Ans: c. 35. On December 20, 1951, the Experimental Breeder Reactor I (EBR-I) in Arco, Idaho, generated usable electricity for the first time. This is considered an important milestone in breeder reactor technology. B Plutonium . Ans: c 14. Fast reactors use heavy water as moderator and coolant. The first unclear power plant in India is located at (a) Kota (b) Kalapakkam (c) Tarapur (d) Baraeilly (e) Kerala. Small fast breeder reactor cores require high fuel density which favours the use of liquid metals as coolant in the restricted space available; large fast breeder cores for commercial-size power plants require less fuel density and in this case the available space in the core is sufficient to permit cooling by pressurized helium. 78. The first experimental breeder reactor (EBR-1) developed was in 1951 in Idaho, U.S.A. Breeder reactor, nuclear reactor that produces more fissionable material than it consumes to generate energy. No moderator is used in the breeder reactor since fast neutrons are more efficient in transmuting U-238 to Pu-239. A Demineralised water . D U₂₃₅ .
