Purification of regenerated uranium in a two-cascade scheme with a dilution operation is proposed. The first cascade has one feed flow, two product flows, and one waste flow. It is calculated as an ideal cascade with adjustment of the obtained 235U concentration to a prescribed content in the exterior flows. Lowenrichment uranium hexafluoride, intended for the fabrication of nuclear fuel, is obtained in the primary product. A product with the same 235U concentration as in the feed flow and reduced 232,234U is produced in the intermediate product of the cascade. This product is enriched with 235U in the second cascade, which is an R-cascade with the key components 235,236UF6. The enriched uranium hexafluoride obtained in the product is diluted to 235U concentration below 5%. The 236U content decreases as a result.
