Assessment of Modeling Approaches for Analysis of Coupled THMC Processes in the EDZ of Geological Nuclear Waste Repositories
This paper presents results of an international, multiple‐code benchmark test (BMT) simulation study on coupled thermal, hydrological, mechanical and chemical (THMC) processes in the excavation disturbed zone (EDZ) around a hypothetical nuclear waste repository in fractured rocks. The paper presents a concise overview and discussion on different model approaches, which were adapted to simulate coupled THMC processes in the EDZ around an emplacement tunnel. We present simulation results of time‐evolution of stress, rock failure and permeability during 100,000 years after emplacement, including an assessment of time‐dependent strength degradation. We concluded that although several promising attempts were made to model coupled THMC processes, including chemically mediated time‐dependent processes, fully coupled THMC models are still lacking and more experimental data to support such models would be needed.
