Short summary
For the deep geological disposal of high-level nuclear waste in rock salt formations, the safety concept includes the backfilling of open cavities with crushed salt. For the prognosis of the sealing function of the backfill for the safe containment of the nuclear waste, it is crucial to have a comprehensive process understanding of the crushed-salt compaction behavior. The KOMPASS projects were initiated to improve the scientific knowledge of using crushed salt as backfill material.

Short summary
It has been claimed that, under repository conditions, rock salt may not be as impermeable as usually considered. We present results of fluid permeation tests on natural rock salt at high temperatures and stresses (140 to 180 °C, 18 and 36 MPa) that refute these claims.
Short summary
Since 2013, the search for a site for a HAW-repository has started again in Germany with the entry into force of the first Site Selection Act (StandAG). Compared to repository concepts in steep inclined salt (domes) or in clay or crystalline formations, a repository in bedded salt offers considerable long-term safety advantages due to a site-specific, natural multi-barrier system consisting of the host rock salt (with the ewG) and overlaying sequences of additional salt and salt clay seams.
