Abstract
SKB, the Swedish Nuclear Fuel and Waste Management Company, has a leading position in developing deep geological disposal technologies and it has introduced the concept of three-dimensional site-descriptive modeling (SDM). SDM provides a holistic view and integrated model of investigated sites in site-selection stage. The model is based on the geoscientific disciplines including geology, rock mechanics and thermal properties, hydrogeology, hydrogeochemistry, bedrock transport properties, and surface ecology. The site-descriptive model is connected to the quality-assured databases containing site investigation data, uncertainties in parameters describing material properties, suggested methods, testing standards, etc. Therefore, it can provide data relevant to repository layout and assessment of long-term safety. In this case study, we summarized the SKB's history of site investigation and site-descriptive modeling, and described workflow and software tools for SDM. We have suggested some items, such as integrated development environment, pilot project, and digital twins, based on experts' reviews on the SKB's SDM-site Report or Safety Assessment Report.
