This paper describes transport modeling performed by the Swedish Nuclear Fuel and Waste Management Company (SKB) within the recently completed SR-Site safety assessment. SR-Site is a part of the license application for building a deep geological repository for spent nuclear fuel in Sweden; this application was submitted to the authorities in March 2011. In the safety assessment, a suite of transport models was used to quantify radionuclide transport through the engineered and geological barriers and in the biosphere. The present paper is focused on the transport in the upper part of the bedrock and in the regolith (the Quaternary deposits overlying the rock). The results presented provide input to the assessment of uncertainties in calculated discharge locations for radionuclide-bearing groundwater from the considered repository volume and to analyses of solute spreading in near-surface and surface systems.
