Summary: | “Mayak” production association has convincingly demonstrated the possibility of creating a HLW partitioning scheme based on different radical phosphine oxide in heavy fluorinated or chlorinated diluents, including in the presence of tributyl phosphate. The separation system makes it possible to efficiently recover uranium, plutonium, neptunium, REE–TPE, as well as technetium from solutions (up to 2 M) in HNO

and separate them into at least two fractions: a fraction of trivalent REE/TPE with the bulk of technetium and a fraction of polyvalent actinides. |
