This report presents the results from the Low Activity Waste (LAW) glass formulation development and testing performed at the Vitreous State Laboratory (VSL) of the Catholic University of America (CUA) from October 2007 to August 2008. The work focused on certain aspects of qualification of LAW glasses for disposal in the Hanford Integrated Disposal Facility (IDF). One focus area was crystallization of LAW glasses containing less than 13.5 wt% and about 13.5 to 17.0 wt% Na₂O, and the effect of crystallization on the behavior of these glasses on the Vapor Hydration Test (VHT) and the Product Consistency Test (PCT). Another area of interest was the performance on VHT of LAW glasses containing about 21 wt% or more of alkali oxides, and the variability in the VHT alteration rates. The VHT data were reviewed and analyzed to identify potential new approaches to modeling the relationship between VHT alteration rates and glass compositions.
