Fig. 12From: Hydro-mechanical evolution of the EDZ as transport path for radionuclides and gas: insights from the Mont Terri rock laboratory (Switzerland)Concept of the EDZ abstraction procedure for safety assessment (SA) applicable for a circular tunnel (after Alcolea et al. 2016): a representative fracture patterns are simulated for relevant repository configurations with a discrete element model (FDEM); b the discrete fracture patterns are converted in heterogeneous porosity and hydraulic conductivity distributions; c in a final abstraction process, the heterogeneous porosity and conductivity distributions are converted into a shell defined by a radius and homogeneous porosity and conductivityBack to article page
