A computational experiment was performed to purify reprocessed uranium hexafluoride from ^232,234,236U in an additional product flow of cascades with a specified number of gas centrifuges in stages. The method used in the calculations takes into account the dependence of the separation coefficients of gas centrifuges on their feed flow and flow division factor. A cascade scheme for purification with simultaneous production of low-enrichment uranium from natural uranium in the main product is investigated. The cascade has to feed flows with regenerated natural-uranium hexafluoride, two product flows, and one waste flow. The cascade parameters that increase the purification efficiency are determined. It is shown that uranium hexafluoride in the products of the cascade satisfies the ASTM C996–15 international specifications established for low-enrichment commercial grading.

进行了计算实验，从^232,234,236纯化后处理的六氟化铀在级联中具有指定数量的气体离心机的附加级联产品流中的U。计算中使用的方法考虑了气体离心机的分离系数对它们的进料流量和分流系数的依赖性。研究了从主要产品中的天然铀同时生产低浓铀的提纯级联方案。级联必须将再生的天然六氟化铀，两个产品流和一个废物流供入流中。确定增加纯化效率的级联参数。结果表明，级联产品中的六氟化铀符合ASTM C996-15国际标准，该标准针对低浓度商业分级而建立。
