Abstract

Natural analogue studies play an important role in the German R&D programme on HLW disposal. Several German research institutions are working in this field often in close co-operation with international partners. Due to the uncertainties in the safety assessment growing with the extended geological time frame, multiple lines of evidence supporting the modelling results as well as the conclusions to be drawn, will be of increasing importance. Information from natural analogues represents one category of supporting arguments. Their role in the safety case depends to some extent on the time period which they cover. Especially industrial or archaeological analogues can help to understand and underpin short-term processes in the repository. However, the main benefit of natural analogues in a safety case is to increase the understanding of long-term processes. This paper gives an overview on German Natural analogue studies performed for more than ten years with regard to a generic HLW-repository in rock salt. It will be briefly shown how natural analogues can contribute to the different elements of a safety case.
