文摘
Some methods for purifying reprocessed uranium from the admixture 232, 234, 236U isotopes in ordinary and double cascades have been considered. The method of purification in a matched abundance ratio cascade (MAR cascade) with a considerable decrease in the 232, 234U concentration in its additional product flow and separation of low-enriched uranium in the main product flow has been proposed. A computational experiment was performed. The results of calculations for MAR cascades with different key uranium isotopes have been presented. The variant that is best for the further enrichment of the purified product in an isolated cascade has been selected.
