The possibility of container compromise within nuclear waste repositories makes it necessary to investigate potential interactions between the repository environment and the materials proposed for storage. Dissolution of the repository contents into the groundwater could result in migration of the radionuclides from the repository. This possible scenario necessitates the investigation of the waste materials solubility in groundwater. The goal of this research was to determine the solubility of mixed uranium oxides in synthetic groundwater of the Snake River plain, under oxic and anoxic conditions at constant pH, in the presence and absence of humic acid. The values for the uranium solubility obtained experimentally and by calculations were compared. © 2000 American Institute of Physics.
