Module 17 Questions – What are the four initial phases of the fuel cycle? Uranium production, Conversion, Research and development, Spent fuel pool water cooling, Enrichment, Fuel fabrication, Post irradiation examination. (Answer: a, b, e, f) What is yellowcake? A powder form of uranium oxide (mainly U3O8), Uranium hexafluoride UF6, Uranium dioxide UO2, Ceramic pellets. (Answer: a) What are the three primary uranium milling/recovery methods? Laser isotope separation, Conventional milling, Gaseous diffusion, In situ recovery/leaching, Heap leaching, Gas centrifugation. (Answer: b, d, e) What three techniques may be used to enrich uranium? Gas centrifugation, Laser isotope separation, Conventional milling, Heap leaching, In situ recovery/leaching, Gaseous diffusion. (Answer: a, b, f) What characterises an open fuel cycle? No spent fuel is generated. The spent fuel is reprocessed. The spent fuel is disposed of directly after irradiation and storage. (Answer: c)
