Geological disposal of low and intermediate-level and high-level waste in Switzerland may - due to corrosion and degradation related processes - result in the production of gas. In our presentation we will focus on the integration of gas related processes and phenomena in the safety case and site selection. In addition, we will elaborate on what technical strategies Nagra follows to limit the potentially detrimental effects on the safety related properties of the technical and natural barriers.
