Two schemes are proposed for purifying regenerated uranium hexafluoride in double cascades. A large flow of native and a small flow of regenerated uranium are fed into the first cascade. One of the external outgoing flows contains low-enrichment uranium with prescribed concentration <5%. The concentration of the second outgoing 235U flow coincides with the regenerated uranium feed concentration. In this flow, corresponding to purified regenerated uranium hexafluoride, the 232,234,236U concentration decreases. The obtained products meet the ASTM C 996–10 specifications for low-enrichment uranium hexafluoride.
