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
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.

Short summary
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.

Short summary
Computer simulations are used to understand processes in nuclear waste disposal. The results are used to judge the safety of waste repository. Not all the information needed for such analyses, e.g. rock properties, is precisely known, contributing to uncertainty in the analysis results. We are interested in understanding the effect of the uncertainty of input quantities and of certain simplifications made during model creation on the outcome of computer simulations.

The SW-A experiment is a large-scale in situ test at the Mont Terri rock laboratory that implements a vertical hydraulic shaft-sealing system in argillaceous host rock. The response of the system and the surrounding rock to hydration is examined. The experiment objectives are to demonstrate the feasibility of installation, to investigate the saturation process, to qualify measurement and monitoring techniques, and to assess the sealing effectiveness. Recent data and experience are presented.

Short summary
The assessment of the integrity of the geological barrier for repositories for nuclear waste can be significantly influenced by uncertainties in the model inputs. Hence, the results of these established integrity analyses should be enriched by statistical information. In this contribution, we present preliminary probabilistic results for rock integrity assessment for the generic repository system in clay rock and the developed tools for stochastic analyses.

Short summary
Triaxial compression tests at different effective stresses allow for analysing the deformation behaviour of Opalinus Clay, the potential host rock for nuclear waste in Switzerland. We conducted microstructural investigations of the deformed samples to relate the bulk hydro-mechanical behaviour to the processes on the microscale. Results show a transition from brittle- to more ductile-dominated deformation. We propose a non-linear failure envelop associated with the failure mode transition.

Short summary
A Sandwich shaft sealing system consists of alternating sealing segments (DS) of bentonite and equipotential segments (ES) with a high hydraulic conductivity. Water accessing the system results in swelling of the DS. Within the ES the water is evenly distributed over the cross section of the seal. Thus, swelling is more homogeneous and seal bypass is reduced. At the Mont Terri rock laboratory, this sealing system is tested in connection with the host rock in a large-scale in-situ experiment.

Short summary
An experimentally deformed sample of Opalinus Clay (OPA), which is being considered as host rock for nuclear waste in Switzerland, was studied by electron microscopy to image deformation microstructures. Deformation localised by forming micrometre-thick fractures. Deformation zones show dilatant micro-cracking, granular flow and bending grains, and pore collapse. Our model, with three different stages of damage accumulation, illustrates microstructural deformation in a compressed OPA sample.

The Federal Institute for Geosciences and Natural Resources (BGR) performs experiments in the Swiss Mont Terri rock laboratory to obtain a comprehensive understanding of the evolution of a repository. Activities and results by BGR from actual and still ongoing experiments are presented exemplarily focusing on main aspects regarding the behaviour of underground facilities. BGR's focus lies mainly on aspects of the construction, post-closure transient, and partly post-closure equilibrium phases.
