The photochemistry of transuranic elements in solution

The literature data on the photochemical reactions of neptunium, plutonium and americium in HNO₃, HClO₄, HCl, H₂SO₄, and Na₂CO₃ solutions as well as certain extraction systems are surveyed. The mechanisms of the photochemical reactions are discussed and it is concluded that those proposed in the literature do not account for those reactions in solutions occurring without added oxidants or reductants. The possibilities of the practical application of photochemistry in the processing of spent nuclear fuel are examined. The bibliography includes 53 references.
