Iron Phosphate Glasses for Vitrifying Doe High Priority Nuclear Wastes
Iron phosphate glasses have been studied as an alternative glass for vitrifying Department of Energy (DOE) high priority wastes. The high priority wastes were the Low Activity Waste (LAW) and the High Level Waste (HLW) with high chrome content stored at Hanford, WA and the Sodium Bearing Waste (SBW) stored at the Idaho National Engineering and Environmental Laboratory (INEEL). These wastes were recommended by Tanks Focus Area because their high sodium, high sulfate, high phosphate, and high chrome content (Table 1) can seriously reduce the maximum waste loading in borosilicate glasses1. All three of these high priority wastes have been successfully vitrified, at high waste loadings, in iron phosphate glasses which have an excellent chemical durability. The research results and identified advantages for vitrifying these three wastes in iron phosphate glasses are summarized below.
