Abstract

The hydration thermodynamic approach to the prediction of glass durabilitywas originally applied to nuclear waste glasses by Jantzen and Plodinec.This approach is useful for control of the production of nuclear wasteglasses. However, improvements are necessary if the approach is to beextended to different glasses, particularly those with higher alkali metalconcentrations. This is of special significance for vitrification of thesalt wastes at Hanford. Various methods for improving the predictive powerof the approach have been examined. Combining a more accurate representationof the alkali metal species in the glass with a more rigorous thermodynamicapproach is a promising avenue to improved predictive power.
