- Аннотация: Extractive treatment of ≥ 0.2 M 239Pu solution in an acidified mixture of tributyl phosphate and octafluoropentanol formal is accompanied by radiolytic degradation of the components. The coefficient of plutonium inter-phase distribution decreases by 4.1 times at 470 kGy α-irradiation dose. Cyclic electron beam radiolysis at 140 kGy increases the residual concentration of plutonium in the organic phase by 3–5 times after re-extraction and by 4–6 times after regeneration. The rate of inter-phase separation is reduced by 5 times during extraction, by 4 times during re-extraction, and by 2–3 times during regeneration.
