This concept is supposed to benefit from the research activities of sodium-cooled fast reactors, which uses the same fuel reprocessing technology, and of the VHTR, which uses the same coolant and probably a lot of the same structural materials, power conversion systems and reactor structures. These reactors use C02 like the coolant & graphite like the moderator. Gas-cooled Reactors. In most light-water, heavy-water, and gas-cooled power reactors, the coolant is maintained at high pressure. These are available in two types namely the Magnox and the AGR (advanced gas-cooled reactor). Ans: a The AGR is a second generation gas-cooled reactor that uses graphite as a neutron moderator and carbon dioxide as the coolant.

It uses uranium fuel, a graphite moderator and a gas as a coolant. Nuclear Power-> Nuclear Power Plant-> Types of Reactors-> Advanced Gas-cooled Reactor. Your email address will not be published. 35. c) Heavy water, C02. 3). The earliest development of gas-cooled reactors began in the United Kingdom (UK) and France. Ans: c. 35. The fast breeder reactor uses the following moderator, Q14. Research reactors have very simple heat-removal systems, as their primary purpose is to perform research and not generate power. In the context of modern scientific research, consider the following statements about lacecube, a particle detector located at South Pole, which was recently in the news. These are available in two types namely the Magnox and the AGR (advanced gas-cooled reactor). Advanced Gas-cooled Reactors (AGR) have been used primarily in UK nuclear generation since the 1980s. The high-temperature gas-cooled reactors (HTGR) use helium gas at about 800 °C and 5 MPa (685 psi) as the primary coolant, graphite as the neutron moderator and fuel element structural material, and coated (Th-U) carbide or oxide fuel particles dispersed in a graphite matrix as the fuel. AGRs were developed from the Magnox type reactor.These are the second generation of British gas-cooled reactors. A gas-cooled reactor is a nuclear reactor that uses graphite as a neutron moderator and carbon dioxide as coolant. The nuclear power plant at Tarapur has the following reactor (a) fast breeder (b) pressurised water (c) boiling water (d) sodium graphite (e) none of the above. Ans: a Gas cooled reactor uses following materials as moderator and coolant. HTGR uses TRISO coated particle fuel, full ceramic core structure, and helium as coolant. b) Lower. Water. These nuclear plants will be established at. The nuclear power plant at Tarapur has the following reactor (a) fast breeder (b) pressurised water (c) boiling water (d) sodium graphite (e) none of the above. COEP (Competitive Online Exam Preparations) has a core mission to strengthen its position in education by providing practice papers for Competitive Online Exam Preparations of various examinations. The nuclear power plant at Tarapur has the following reactor (a) fast breeder (b) pressurised water (c) boiling water (d) sodium graphite (e) none of the above. Gas cooled reactor uses following materials as moderator, ... Gas cooled reactor uses following materials as moderator, and coolant_____? The nuclear power plant at Tarapur has the following reactor (a) fast breeder (b) pressurised water (c) boiling water (d) sodium graphite (e) none of the above. Graphite is typically used to moderate reactions involving natural uranium fuel. Q8. The two commercial reactor types based on this principle are both American designs, but are widely used in over 20 countries. A nuclear fission produces energy of following order in mev, Q11. Q1. The original gas-cooled reactors in the UK were designed with natural uranium fuel cladded in a magnesium alloy, hence the name Magnox. In the Mark I type the coolant is carbon... | Meaning, pronunciation, translations and examples The coolant system plays a pivotal role in performing this function. A larger second-generation version is the advanced gas-cooled, graphite-moderated reactor (AGCR). 8). non-fertile materials) and thus use ordinary water as both a moderator and a coolant. Because the reactor is dry-cooled and uses virtually no water to operate, it can be sited nearly anywhere, it said. a) Graphite, C02. Figure 1.2 Schematic: Pressurised Heavy Water Reactor (CANDU) Water Cooled and Moderated By moving to greater levels of enrichment of U235, it is possible to tolerate a greater level of neutron absorption in the core (that is, absorption by non-fissile, non-fertile materials) and thus use ordinary water as both a moderator and a coolant. Q10. Gas Cooled Reactor: This type of reactor employs a gas (CO 2 or helium) in place of water as the coolant and graphite as the moderator. 4). The resulting design, known as the Advanced Gas-Cooled Reactor (AGR) It uses graphite as the moderator and CO2 as a coolant Steam pressure is around 150 atmospheres and temperature around 5500C Its overall efficiency is about 40% Reactors installed at Calder Hall and Berkely In UK in 1957 are gas cooled reactors. The fuel used in the Magnox is natural uranium whereas, in the AGR, it uses enhanced uranium. Gas cooled reactors: carbon dioxide (CO2)/ Helium These are the coolants used in respective reactors. Although there are many other types of reactor cooled by gas, the terms GCR and to a lesser extent gas cooled reactor are particularly used to refer to this type of reactor. A gas reactor or GCR (English gas cooled reactor) is a type of nuclear nuclear reactor of nuclear fission. The first nuclear power plant in India is located at, Q15. d) The material which absorbs neutrons and undergoes spontaneous changes leading to the formation of fissionable material, a) %age of U235 has been artificially increased, b) %age of U has been artificially increased, c) %age of U234 has been artificially increased. The nuclear power plant at Tarapur has the following reactor (a) fast breeder (b) pressurised water (c) boiling water (d) sodium graphite (e) none of the above.
