Short summary
The planned use of crushed salt as the backfill and sealing material for the final disposal of radioactive waste in rock salt is justified by the favorable crushed salt material properties. A prognostic long-term safety assessment requires sufficiently proved physical modeling that can only be met on the basis of suitable laboratory and field investigations. To reduce the currently existing uncertainties, triaxial long-term compaction tests TUC-V2 and TUC-V4 (KOMPASS II) were carried out.
