Site specific evaluation of safety issues for high-level waste disposal in crystalline rocks

The results of this project provide a condensed overview of the manifold site-specific safety investigations regarding HLW disposal in crystalline host rocks. The investigations were performed by BGR, GRS, and DBE TECHNOLOGY GmbH in the past years in close cooperation with VNIPI PT and other Russian organizations involved in the investigation of the Yeniseysky site near Zheleznogorsk in the Krasnoyarsk region. The investigations focused mainly on major long-term safety aspects of HLW disposal in crystalline rocks, in particular on the performance of the geologic and engineered barrier system. It was not intended to perform a comprehensive preliminary safety analysis; however, these investigations address a wide range of issues that need to be considered in a safety analysis, and the results can be used as guidance for necessary future investigations.
