Solubility of plutonium nitrate in uranyl nitrate hexahydrate melt

Radiochemistry Aims and scope

Abstract

At a weight fraction below 20%, Pu(IV) nitrate is isomorphically dissolved and homogeneously distributed in the uranyl nitrate hexahydrate phase, the solubility being independent of the HNO3 concentration in the mixed U-Pu melt up to the acid concentration of 7 M. In dissolving solid Pu(IV) nitrate in 1–6 M HNO3, Pu(IV) disproportionates to form Pu(III) and Pu(VI). With increasing HNO3 concentration to above 10 M, Pu(IV) passes into solution as Pu(NO3) 2−6 , and no disproportionation is observed.
