Vitrification studies of actual Savannah River M-Area mixed wastes haveshown that the limiting factor for high waste loading of this waste streamis its chemical durability as defined by the toxicity characteristicsleaching procedure (TCLP). As part of the optimization study of SavannahRiver M-Area wastes, a number of additives were examined including Na2O, Li2O, B2O3, ZrO2, and TiO2. This paper reports on the effect ofvarying the boron to total alkali ratio and on the effect of substitutionssuch as ZrO2 for waste and TiO2 for SiO2 onthe chemical durability and processability of M-Area waste glasses.
