Hydrothermal Interaction of Simulated Nuclear Waste Glass in the Presence of Basalts
One of the leading candidate waste forms for disposal of commercial high level nuclear waste is glass. This waste form has received a great deal of attention over the past twenty years of development. Alteration of this waste form in the presence of mild hydrothermal solutions, which might be anticipated during the first several hundred years after emplacement of the waste into a geological repository, was shown (1) to be extensive at 300°C. These stability experiments, however, were conducted in a closed static hydrothermal system with the waste form and deionized water alone.
