THE EFFICIENCY OF USING DOUBLE CASCADES WITH A CARRIER GAS FOR ENRICHING REPROCESSED URANIUM UNDER THE CONDITIONS OF A MULTIPLE RECYCLE

An estimate has been made of the potential of a double cascade with a carrier gas for enriching reprocessed uranium under the conditions of a multiple recycle. This scheme makes it possible to obtain low-enriched uranium with simultaneous fulfi llment of limitations on concentrations of even-numbered isotopes, fi rst of all, ²³²U, but is unable to prevent ²³⁶U concentration, which entails the need for increasing ²³⁵U enrichment. Hence, since ²³⁶U isotope is responsible for accumulating ²³²U as its daughter isotope, this results in accumulation of ²³²U with a rise in the number of processing cycles and reuse.
