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.

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.

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.

Within the scope of the presentation, a methodical approach for the systematic and structured development and validation of multiphysical material models, which has been successfully tested several times in the meantime, will be introduced and subsequently the concrete application of this methodology will be presented using the example of a material model taking into account the triaxial stress-strain behavior of crushed salt.

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.

In Switzerland, the Opalinus Clay (OPA) formation is favored to host a repository for nuclear waste. Thus, we must know its deformation behavior. In this study, we focused on the microstructure of gouge, a thin (< 2 cm), drastically strained clay layer at the so-called Main Fault in the Mont Terri rock laboratory. We suggest that in situ gouge deforms in a more viscous manner than undeformed OPA in laboratory conditions. Moreover, we speculate about the origin and evolution of the gouge layer.

Scaly clay is a well-known rock fabric that can develop in tectonic systems and that can alter the physical rock properties of a formation. However, the internal microstructure and evolution of this fabric remain poorly understood. We examined the scaly microstructure of progressively faulted Opalinus Clay using optical as well as scanning electron microscopy. We show that as little as 1 vol.% in scaly clay aggregates is strained and present an evolutionary model for this.
