Mass-transfer-limited release of a soluble waste species

The authors have earlier presented analytical solutions for the rates of dissolution of solubility-limited species from solid waste imbedded in saturated porous rock. The dissolution rate of some species, however, may not be limited by solubility of the species or of the waste matrix. For example, the portion of the fission product cesium and iodine in spent fuel that exists in the fuel/cladding gap and in voids and grain boundaries is available for rapid dissolution if exposed to ground water. Even though dissolution may be rapid, the rate of release of these soluble species from the waste package will be limited by the rate of mass transfer of the dissolved species through the surrounding porous media. Here the authors present the results of a new mass transfer analysis of the time-dependent release rate of species that can dissolve rapidly from the gap activity and more slowly from the waste matrix, as limited by molecular diffusion into surrounding porous rock.
