Short summary
Short summary
In a deep geological repository for radioactive waste disposal, corrosion of metals can lead to the formation of gas. This work investigates the gas flow and release pathways in different sections of the repository using computer simulations. The focus is on the description of the method and workflow to develop these models.

Short summary
Short summary
A numerical model integrating the structure and mechanical properties of a sedimentary sequence in the Alpine foreland is presented to show that topography, tectonic faults and, most of all, spatialy variable rock properties affect the state of stress at depth. The tectonic forces acting on the sequence are primarily taken up by the stiff rock units leaving the weaker units in a stress shadow.
Short summary
The work presents decades of experience of performance assessment to support selection process in Switzerland, which includes complex THMC coupled physical processes, lifecycle assessment, probabilistic assessment, and integrated regional-, repository-, component-scale models. The final evaluation was made integrating a wide range of information, including regional stress conditions, tectonic structures, stratigraphy, lithology, mineralogy, and the impact from effects induced by the repository.
