Enrichment of Regenerated Uranium in a Gas Centrifuge Cascade with Simultaneous Dilution of 232,236U by Waste and Low-Enrichment Uranium

Abstract

It is shown that regenerated uranium can be enriched in a gas centrifuge cascade with three feed streams (waste uranium, low-enrichment uranium, regenerated uranium) and simultaneous dilution of the isotopes ^232,234,236U. Computational experiments were performed for different ²³⁵U content in the low-enrichment feed. The chosen combination of diluents makes it possible simultaneously to lower the separative work expenditure and reduce the consumption of native raw material with respect to not only previously used multi-stream cascades but also a standard cascade for enrichment of native uranium.
