ThermoQuakes 3D thermo-mechanical modelling of seismicity related to the final disposal of spent nuclear fuel and radioactive waste in hard rock (SSM, 2015-2017)

The Swedish Radiation Authority (SSM) is the Swedish regulator for the process to build a deep geological repository for high-level radioactive waste. For the selected site Forsmark we model the impact of thermal and earthquake loads on the naturally fractured crystalline rock mass surrounding the repository and their association with complex geologic structures. Besides the thermo-mechanical processes the model can also simulate the induced seismic events (TM-D model) from dynamic rupturing as well as those arising from dissipation of the energy in form of seismic waves.
