OWL models update and use for TWRS strategy development
High Level Waste (HLW) at Hanford will be converted to a borosilicate glass for disposal. The glass will need to meet both processability and durability restrictions. The processability conditions will ensure that the glass has properties (viscosity, electrical conductivity, and liquidus temperature) within ranges known to be acceptable for the vitrification process. Durability restrictions will ensure that the resultant glass will meet quantitative criteria for disposal in a repository. An experimental program, the Composition Variation Study (CVS), is developing property models which correlate physical properties to glass compositions. Property models have been developed for the viscosity, electrical conductivity and liquidus temperature of the glass melt, and durability of the glass. The property models are described in the above report. Bounds on property values, limits on the composition of individual components in the glass, and other restrictions are also published in the report.
