From page 20...
... Present models suggest that under certain conditions the expected lifetime of the glass may be extended; however, there can be wide variations in the extrapolated behavior depending on the model used. At present, there appears to be poor communication between those who conduct the performance assessments of waste form behavior and those who study glass corrosion.

From page 21...
... The Hanford tank wastes offer the opportunity to build on this success, as well as to improve the present technology and consider new approaches (e.g., new glass compositions, sintered glass, glass ceramics, crystalline ceramics, cold-wal1 crucible technology)
