Solubilities of Actinides in a Domestic Groundwater

Solubility limits and speciation data of nuclides in a groundwater are important for understanding an aqueous radionuclide transport through a geosphere in a high level waste repository. They define the source term for transport retardation processes such as a sorption and colloid formation, and are useful in verifying the validity of geochemical codes that are part of the predictive transport models. In this study, the solubilities of actinides with a long lifetime in a domestic granitic ground water were calculated by PHREEQC (V.2), and the results are compared with the values reported in other literatures
