(GRS 241) Impact of climate change on far-field and biosphere processes for a HLW-repository in rock salt

The assessment of the long-term safety of a repository for radioactive or hazardous waste requires a comprehensive system understanding and capable and qualified numerical tools. All relevant processes which contribute to mobilisation and release of contaminants from the repository, transport through the host rock and adjacent rock formations as well as expositionin the biosphere have to be implemented in the programme package. The objective of the project “Scientific basis for the assessment of the long-term safety of repositories”, identification number 02 E 9954, was to follow national and international developments in thisarea, to evaluate research projects, which contribute to knowledge, model approaches and data, and to perform specific investigations to improve the methodologies of the long-term safety assessment.
