Site-specific analysis of repository performance - four years to go to site selection

Site investigations for the spent fuel repository in Finland are under way at three sites. One of them is near the Olkiluoto nuclear power plant at the coast of the Baltic sea. The two other investigation sites are inland. The site of the repository shall be selected by the end of 2000. The aim of the site-specific safety analyses is to scrutinize whether the updated canister and repository designs with site-specific repository layouts fulfil the safety requirements, and to evaluate whether there are any significant differences in the post-closure performance of the planned repositories at the three sites. The paper includes preliminary results from the interim report on safety analysis (TILA-96) to be published at the end of 1996. (author)
