Improved Loading of Sulfate-Limited Waste in Glass
Conference
·
OSTI ID:990151
The loading of many wastes in borosilicate glass are limited by the allowable sulfate concentration (e.g., Hanford low-activity waste [LAW] and Idaho National Laboratory [INL] sodium-bearing waste [SBW]). By the Hanford baseline formulation method, the tolerated amount of sulfate in LAW is 0.77 wt% (as SO3) at the lowest soda contents, decreasing to 0.35 wt% at the highest soda contents. Roughly half of the Hanford LAW (on a glass mass basis) will be limited by sulfate tolerance of the glass melt. If the allowable concentrations of sulfate were to be increased only moderately, the cost and time required to vitrify the Hanford LAW would be significantly reduced.
