Enrichment of Regenerated Uranium with Simultaneous Dilution of 232–236U by Raw and Waste Uranium

A scheme is proposed for a five-flow (three feed, product and waste flows) gas-centrifuge cascade for enriching regenerated uranium simultaneously diluted by natural raw material and waste uranium. Computational experiments show the advantages of such a cascade in terms of the consumption of natural uranium with respect to the previously proposed multiflow cascades. In contrast to previously proposed cascades for enriching regenerated uranium, this cascade makes it possible to vary the consumption of natural uranium in obtaining products of equivalent quality, which makes it possible to seek and pick the optimal way to enrich the regenerated material in order to obtain VVER fuel.
