Question No : 37 Which of the following nuclear reactor does not need a heat exchanger for generation of steam? Uranium is present naturally in virtually all soil, rock and water. Uranium enrichment is a process that is necessary to create an effective nuclear fuel out of mined uranium by increasing the percentage of uranium-235 which undergoes fission with thermal neutrons.Although many reactors require enriched uranium fuel, the Canadian-designed CANDU, the British Magnox reactor and the proposed Molten salt reactor can use natural uranium as their fuel. U238 will undergo fission by In the United States, uranium ores contain from 0.05–0.3% of the uranium oxide U 3 O 8; the uranium in the ore is about 99.3% nonfissionable U-238 with only 0.7% fissionable U-235. 38. There was some hope that the enrichment process would be improved and fissionable isotopes of U-235 could, at some future date, be extracted from the depleted uranium. According to the Ronen fissile rule, for a heavy element with 90 ≤ Z ≤ 100, its isotopes with 2 × Z − N = 43 ± 2, with few exceptions, are fissile (where N = number of neutrons and Z = number of protons). © Copyright 2016-2020 - www.PakMcqs.com/.
