Abstract

This research is the ECN contribution to the salt option of the EC project on performance assessment of geological isolation systems (Pagis) for high-level waste disposal. The evaluation concerns a repository mined in a medium-sized salt dome, the normal evolution scenario of which is assumed to be a continuous subrosion of the salt dome. The geohydrological model is based on the assumption that subrosion started 1.2 x 10**6 years ago and future climatic changes remain limited to a continuing Quaternary type of development in average temperature. Subrosion rates are calculated by a model which make use of a modified SW1P-2 computer code and is described in Section I. The results of calculations on both the flank and top subrosion are given in Sections II and III. They show that, even under very conservative assumptions, the isolation capability of the salt dome, with an adequately designed repository is at least in the order of a million years.
