Description

A measure of the ability of a particular substance (e.g. radionuclide-bearing solids) to dissolve in a particular solvent (e.g. water), equal to the quantity of substance dissolving in a fixed quantity of solvent to form a saturated solution under specified conditions (e.g. temperature, pressure, pH, redox). The conditions affect the chemical form and speciation of the substance. Thus, different species of the same element may have different solubilities in a particular solution.

Description of FEP Effects

The concentration of radionuclides in aqueous solution may be limited by the solubility of the waste, or of radionuclide-bearing solids formed by the interaction of the waste and buffer pore fluids.
