The effect of a stationary precipitation front on nuclide dissolution and transport: Analytic solutions
Waste material in a geologic repository will dissolve and migrate away. For many components, this process will be limited by the solubility of the waste matrix and species involved. In this paper we deal with a single contaminant species and analyze the effect of a precipitation front caused by a discontinuity in the solubility of the contaminant at some distance from the waste package. The precipitation front may be due to local geochemical changes such as changes in temperature, pH or redox potential, caused by nearby geologic features or the waste itself. In contrast with other work on precipitation fronts, we provide analytic solution to the problem of precipitation at a stationary front. Numerical illustrations of these solutions are also presented. 5 refs., 2 figs.
