Abstract The dissolution behaviour of two alloys, which represent the metallic precipitates, occurring in the dissolution step of a nuclear reprocessing plant was investigated. The solubility of these alloys, containing Mo, Ru, Rh and Pd, in HNO3-solutions is rather low and dissolution ceases after some time, caused by passivation. A significant acceleration of the dissolution rate takes place if ozone is passed through the alloy/HNO3-suspension, or if an electrolytic dissolver with or without an oxidation catalyst is used. Moreover, Ru can be separated as RuO4 by distillation.
