Sažetak
Innovation presented here is inclusion of the excavation induced damaged zone into numerical model, which in other simulations of this type was not readily done, which is evident in the existing literature. Damaged zone is singled out as a separate important region of the model and a potential problem – a zone of faster groundwater flow and a potential propagation path for radionuclides, lower mechanical properties of the rock and significant influencer in the heat transport. This significantly improves the numerical modelling of thermo-hydro-mechanical properties of the spent nuclear fuel repository and the determination of the qualitative characteristics and functionality of the repository. Proving that the model and the concept of the repository is within the required parameters, from the point of view of radionuclide retention, basically proves the functionality of the concept, which is one of the most important parts of the “safety-case” development and demonstrating the safety of the repository to stakeholders.
