A two-stage scheme is proposed to reduce the concentration of ^232,234,236U in regenerated uranium hexafluoride. In the first cascade, waste uranium hexafluoride, whose contaminated stream is taken in the additional product, is directed into the additional feed. The main product stream of the first stage, enriched in ²³⁵U, is directed to the feed of the second stage. Its waste purified from ^232,234U is diluted to ²³⁵U concentration <5%. A computational experiment was performed on the basis of methods for calculating cascades with separation coefficients corresponding to gas centrifuges. It was shown that in terms of ^232,234U content the product obtained after dilution meets the requirements of the ASTM C996-15 specifications for the commercial grade uranium hexafluoride. The ²³⁶U content in it is several-fold lower than in the enrichment of regenerated uranium hexafluoride without purification.

提出了一个两阶段方案来降低再生六氟化铀中^232,234,236 U的浓度。在第一个级联中，废六氟化铀，其污染流被带入附加产品中，被引导到附加进料中。富含²³⁵ U的第一阶段的主要产品流被引导至第二阶段的进料。其从^232,234 U纯化的废物被稀释至²³⁵ U 浓度 <5%。在计算具有对应于气体离心机的分离系数的级联的方法的基础上进行了计算实验。结果表明，就^232,234U含量稀释后得到的产品符合ASTM C996-15商品级六氟化铀规范的要求。其中的²³⁶ U含量比未经纯化的再生六氟化铀浓缩低几倍。
