Abstract:

An experimental program is described wherein the effect of important independent variables on glass reaction under conditions that may exist for unsaturated storage is examined. The effect of radioactive vs. simulated glasses is being examined in a set of simple and integrated tests. Results through 140 days show that no major differences exist between the two glass types although some trends are being established that need further examination. The effect of SA/V was examined in preliminary tests done at 10, 50, and 100 m^-1. Analysis of the reacted glass structure indicated that as the SA/V changed, the assemblage of crystalline phases that formed on the reacted glass varied and the process by which the glass structure reacted changed. Finally, the effect of radiation on glass reactivity is being studied. For each variable studied, tests are in progress that will provide information to support startup of the glass processing facilities and licensing of a repository.
