Abstract

The effect of a concrete-based repository on local geological conditions and properties has been explored. As part of a complete description of repository behaviour, a static model of clay-alkali interactions has been set up. Parallel experiments have demonstrated the buffering capacity of clays, and are indicating the chemical and physical changes that may occur when an alkali plume interacts with a clay host rock.
