Abstract

Interface reactions between two nuclear waste borosilicate glasses and repository components have been studied in an in-situ burial experiment in Stripa mine, Sweden. Exposures up to one year have been analyzed and are reported.

The results obtained up to date show an increased depth of attack ranging by: increased severity from the glass/granite interfaces, glass/glass interfaces to glass/bentonite interfaces. The rate and extent of surface attack is discussed in terms of ion exchange with species from the groundwater and leached from the repository components.
