Abstract

The review of research presented in Part 1 comprises a summary of work on environmental change as applied to proposed radioactive waste disposal sites in various countries around the world. The focus on environmental change arises from the awareness that, where long-term safety is of concern, some appreciation for potential or likely future changes in the environment must be realised. Following a review of work in this field, some consideration is given to application and methodology. Two principal approaches are discussed, namely, scenario assessment and environmental simulation. Although these approaches are somewhat complementary, the latter is favoured as a basis for performance assessment. Part 2 of the document presents research addressing one aspect of long-term site evolution which is of particular concern. The subject matter concerns the growth of permafrost in association with glaciation, and the potential effects of permafrost on groundwater systems. Although much work exists on the growth of ice in soils at shallow levels, relatively little is known on the growth of deep permafrost. A short overview of the work is accompanied by a large appendix presenting the conclusions of theoretical work.
