Abstract
Vitrification studies of actual Savannah River M-Area mixed wastes have shown that the limiting factor for high waste loading of this waste stream is its chemical durability as defined by the toxicity characteristics leaching procedure (TCLP). As part of the optimization study of Savannah River M-Area wastes, a number of additives were examined including Na2O, Li2O, B2O3, ZrO2, and TiO2. This paper reports on the effect of varying the boron to total alkali ratio and on the effect of substitutions such as ZrO2 for waste and TiO2 for SiO2 on the chemical durability and processability of M-Area waste glasses.
