This report provides the results from the chemical analyses of a sulfur-saturated melt versions of the Low-Activity Waste High PCT and VHT Response study glasses, which are a series of simulated nuclear waste glasses designed and fabricated at Pacific Northwest National Laboratory. These data will be used in the development, validation, and implementation of enhanced property/composition models for waste glass vitrification at Hanford. Chemical analyses were performed on a representative sample of each of the sulfur-saturated melt versions of the glasses to allow for comparisons with targeted compositions, as well as the measured compositions of the quenched glasses. The relative differences between the targeted and measured concentrations of B₂O₃, K₂O, Li₂O, V₂O₅, and ZrO₂ for several of the glasses were greater than ±10%. The relative difference between the targeted and measured concentrations of SO₃ were greater than 10% for all study glasses. The wash solutions contained mainly sodium, sulfur, and sulfate ions.
