Drobyishevskiy, E.V. Moiseenko, R.A. Butov, Y.N. Tokarev ANNOTATION: The long-term simulations of the thermal state were performed for the layout based on the radioactive waste repository project in Nizhnekansky Rock Massif. The 3D finite-element computer code FENIA was developed as a tool for simulation of thermal processes in deep geological repositories. Further the models for mechanical phenomena and groundwater hydraulics will be added resulting in a fully coupled thermo-hydro-mechanical (THM) solution. The obtained results describe the spatial and temporal evolution of the temperature filed inside the repository and in the surrounding rock for the duration of 10 000 years. These results show that practically all generated heat was ultimately absorbed by the host rock without any significant temperature increase. Still in the short time span the temperature maximum exceeds 100 °C.
