Challenge • Typical characteristics that make a rock mass suitable for nuclear waste storage include low hydraulic conductivity, low diffusion coefficients, good retention capacity for radionuclides, and potential for self-sealing of fractures. • A major concern is that the isolation properties of the rock mass could be negatively impacted by rock fracturing during construction of underground structures such as emplacement tunnels and caverns. Therefore, the analysis and prediction of the excavation damaged zone (EDZ) and its evolution with time is a crucial step for the assessment o
