The process by which a heavy nucleus is split into two light nuclei is known as, Q12. d) Lead, H2 . The high-temperature gas-cooled reactor (HTGR) is similar in concept to the AGR. 4). 3. Gas cooled reactor uses following materials as moderator, and coolant_____? 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. a) Same. U-233 and Pu-239; U-23i and Pu-233; ... moderator should be used; coolant should be employed; ... 10. Nuclear Reactor Types 3 The most widely used reactor … 10). b) Lower. Gas cooled reactors: carbon dioxide (CO2)/ Helium These are the coolants used in respective reactors. a) Same. Which of the following particles is the lightest? The fast breeder reactor uses the following moderator, Q14. It used due to its availability and high heat capacity, both for cooling and heating. Magnox reactors (see Fig 1) were built in the UK from 1956 to 1971 but have now been superseded. c) Heavy water, C02. Gas cooled reactor uses following materials as moderator and coolant. the following reactor (a) fast breeder (b) pressurised water (c) boiling water (d) sodium graphite (e) none of the above. The breeding gain in case of thermal breeder reactor as compared to fast breeder reactor is. Ideally the neutron flux in reactor should be, Q18. Save my name, email, and website in this browser for the next time I comment. 4.4 SAFETY ASPECTS OF THE PBMR . Ans: a Gas-cooled reactor definition: a nuclear reactor using a gas as the coolant . It doesn’t have a moderator. It doesn’t have a moderator. A stage-Ill reactor involves a self-sustaining series of … 2. Your email address will not be published. 2). Carbon dioxide coolant removes heat from the reactor core, then travels to a heat exchanger. A larger second-generation version is the advanced gas-cooled, graphite-moderated reactor (AGCR). 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. The turbine can discharge its gas into a large, low pressure cooler to return the gas to the initial compressor inlet conditions. The fuel used in the Magnox is natural uranium whereas, in the AGR, it uses enhanced uranium. The fuel used in the Magnox is natural uranium whereas, in the AGR, it uses enhanced uranium. An Advanced Gas-cooled Reactor ( AGR) is a type of nuclear reactor designed and operated in the United Kingdom. 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. Gas cooled reactor uses following materials as moderator, and coolant. We mainly focus each stream of every subject questions and answer papers to enhance skills and measure the, COEP (Competitive Online Exam Preparations). The relative properties of these materials are compared below. Like helium and CO2, nitrogen is compatible with the graphite that is used as a moderator and structural material in gas cooled reactors. Its use is limited to the United Kingdom; it is sometimes known as the Magnox reactor. The breeding gain in case of thermal breeder reactor as compared to fast breeder reactor is, Q9. AGRs were developed from the Magnox type reactor.These are the second generation of British gas-cooled reactors. non-fertile materials) and thus use ordinary water as both a moderator and a coolant. Page-6 section-1 HTGR uses TRISO coated particle fuel, full ceramic core structure, and helium as coolant. In nuclear fission each neutron that causes fission releases, Q8.
