Abstract Recent glass formulation activities have focused on developing alternative frit compositions for use with specific sludge batches to maximize melt rate and/or waste throughput. The general trend has been to increase the total alkali content in the glass through the use of a high alkali based frit, a less washed sludge, or a combination of the two. As a result, predictions of durability have become a limiting factor in defining the projected operating windows for the Defense Waste Processing Facility (DWPF) for certain systems. An additional issue for these high alkali glasses has been the effect of REDuction/OXidation (REDOX) on the durability of the glass. Recent analyses have indicated that the application of the durability model's value without consideration of the overall glass composition may lead to a more significant shift (larger magnitude) than needed.
