Short summary
The German search for a disposal site for high-level nuclear waste is in its first phase. In the so-called representative preliminary safety assessments the possible future evolutions of potential disposal sites will be developed from our understanding of their past evolution. Erosion processes connected to glaciations can reach especially deep and could threaten a repository, while being very hard to predict. This makes them important to the site selection process.
