Abstract Scope |
Traditional laboratory testing has led to an enhanced understanding of glass corrosion as we assess the extent of the release of glass components into solution as a function of time and temperature. Three tests studied here are primarily used on glasses destined for disposal facilities although each analysis provides different information. Vapor hydration test data reveals that even for replicated samples the results were not consistently reproducible. EPA1313 is another test performed to evaluate glass corrosion and the reproducibility was assessed through comparing literature values with experimental results. The third analysis, Stirred Reactor Coupon Analysis, can provide beneficial information to support modeling, and further data analysis on additional glasses assessed here will also support that modeling. This presentation will discuss the three tests mentioned above and how the results tie to WTP operations. |
