232,234,236U Removal from Contaminated Waste Uranium Hexafluoride in a Double Cascade
- 19 Downloads
Two schemes with double cascades are presented for purifying waste uranium hexafluoride with high 232,234,236U content. A large flow of native uranium hexafluoride and a low flow of waste uranium hexafluoride are fed into the first cascade. One of the external outgoing streams contains low-enrichment uranium hexafluoride with prescribed 235U concentration <5%. The 235U concentration of the second outgoing stream coincides with the feed concentration of waste uranium hexafluoride. 232,234,236U concentration reduction occurs in this stream, corresponding to purified waste uranium hexafluoride. The obtained products can be used effectively for enrichment in a cascade meeting ASTM C 996–15 specifications for low-enrichment commercial uranium.
