Abstract
A dual-cascade system for the purification of regenerated uranium hexafluoride from 232, 234, 236U is proposed. In the first cascade, regenerated uranium is enriched to a 235U concentration of no less than 20% with a decrease in the mass 236U/235U ratio. Its additional feed flow is waste uranium hexafluoride, whose contaminated flow is removed as an additional product. The second additional feed flow is natural uranium hexafluoride. The main product flow from the first cascade is sent as a feed flow to the second cascade. Its waste purified from 232, 234U is diluted with low-enriched or natural uranium hexafluoride to the 235U concentration less than 5%. A numerical experiment is also performed. It is shown that the product formed after diluting the waste of the second cascade satisfies the ASTM C996-20 specification requirements for enriched commercial uranium hexafluoride in terms of 232, 234, 236U.
