A program has been established for DOE Environmental Restoration and Waste Management (EM) to evaluate factors that are likely to affect waste glass reaction in an unsaturated environment typical of what may be expected for the candidate Yucca Mountain repository site. This report covers progress in FY 1990 on the following five tasks: (1) A critical review of those parameters that affect the reactivity of glass in an unsaturated environment is in progress. This effort involves a search of literature to identify the important parameters. Temperature is the first parameter examined in detail, and a draft report has been completed. (2) A series of tests has been started to evaluate the reactivity of fully radioactive glasses in a high-level waste repository environment and compare it to the reactivity of synthetic glasses of similar composition. (3) The effect of radiation upon the durability of waste glasses at a high glass surface area-to-liquid volume (SA/V) ration and high gas-to-liquid volume ratio will be assessed. The conditions of these tests will be typical of an unsaturated environment. (4) A series of tests is being performed to compare the extent of reaction of nuclear waste glasses at various SA/V ratios. Such differences in the SA/V ratio may significantly affect glass durability. (5) Analytical electron microscopy is being used to assess the glass/water reaction pathway by identifying intermediate phases that appear on the reacting glass.
