Time Frame: 2022-2026

Funding: BGE

    Principal Investigator:Oliver Heidbach , Moritz Ziegler

    Personnel: Sophia Morawietz

      The tectonic stress field in the Earth's crust affects a large number of site selection criteria for the management of radioactive waste. Within the project SpannEnD the Germany-wide, geomechanical-numerical 3D model will be further refined. This model has been calibrated against stress data and based on continuum-mechanical approaches it allows predictions for areas without stress data and the predict the six independent components of the 3D stress tensor. In addition, we will further develop tools that allow the transfer across to allow for consistent predictions between the Germany stress model and local models on repository scale (see Figure). In this phase our research is independent of host rocks and does not focus on any particular region. The goal is to provide basic research results, stress data and tools needed to generate in the future geomechanical-numerical models for selected siting areas with given host rock conditions.
