Durability of glasses from Pacific Northwest Laboratory Composition Variability Study-II (CVS-II)
Pacific Northwest Laboratory (PNL) is developing a borosilicate glass as a solid, stable medium for the disposal of high-level radioactive waste at the Hanford site. They are optimizing the glass forming region and developing process models to be used in the Hanford Waste Verification Project (HWVP). Their experimentally-based statistical approach for optimizing the glass composition for HWVP has been designated the Composition Variability Study (CVS). In Part 1 of the CVS study PNL tested wide ranges of composition developed first-order empirical models, and provided input for planning CVS-2. In part 2, they are generating glass property data for a number of compositions in order to develop second-order empirical models which will be used to identify the composition region that simultaneously satisfies all quality and processability requirements of HWVP.
