It is proposed to use an ordinary three-stream cascade with several types of stages in terms of the number of gas centrifuges in order to lower the 232,234U concentration in reprocessed uranium hexafluoride. Its parameters, giving a high output of the product with close to feed concentration of 325U going into the waste and considerably lowered 232,234U were determined. A high-activity product, which it is expedient to dilute with waste uranium hexafluoride to a nuclear safe mixture with 235U concentration <1%, is formed in the product. A computational experiment was performed. It is shown that in terms of 232,234U the post-enrichment product meets ASTM C996-20 specifications for enriched commercial uranium hexafluoride.
