Aspects of the lowering of the 232,234,236U concentration in regenerated uranium hexafluoride are considered. A three-cascade purification scheme including dilution with waste uranium or natural raw material at an intermediate stage is proposed. A computational experiment was performed to determine the parameters of purification of regenerated uranium hexafluoride of each isotope 232,234,236U. It is shown that the overall product formed after dilution with natural raw materials and enrichment in a third cascade satisfies the ASTM C996-20 specifications for enriched commercial uranium hexafluoride.
