PHOTOCHEMISTRY OF TRANSURANIUM ELEMENTS IN SOLUTION

Literature data on the photochemical reactions of neptunium, plutonium and americium in HNO3, HClO4, HCl, H2SO4, and Na2CO3 solutions and some extractive systems are summarized. The consideration of mechanisms of photochemical reactions proposed in literature showed that these mechanisms could not explain the proceeding of photochemical reactions in solutions in the absence of oxidants or reductants. The possibilities of practical using of photochemistry to nuclear fuel reprocessing are discussed.
