Extract

Hydrodynamic modelling on the site- and repository scale was aimed at testing the performance of both, geological and engineered barriers as part of the Swiss program for disposal of high- and intermediate-level radioactive waste. Conceptual and parameter uncertainties were addressed by sensitivity studies to explore the robustness of the overall disposal concept. Consistency was demonstrated between modelling results and hydrogeological and geochemical evidence from the Benken borehole, increasing confidence in the comprehension of the key hydrogeological features of the candidate repository site. Assessment of a wide spectrum of repository closure conditions highlighted the function of the waste confinement concept. Visualisation and animation of the modelling results has proven to be of great help in communicating the level of comprehension of groundwater movement in the vicinity of a potential repository in the Zürcher Weinland.
