Abstract

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