2011:26 The influence of temperature and fluid pressure on the fracture network evolution around deposition holes of a KBS-3V concept at Forsmark, Sweden
about 500 m depth and embedded in clay. Thus, the rock, the clay and the copper canister are acting as barriers in order to retard the possibility of spent fuel to escape the repository and reach the biosphere ... (e.g. millions of years), the rock will be subjected to thermal, mechanical and hydraulic changes that can induce failure and propagation of the existing fractures providing new pathways for the spent fuel...

2011:25 Report from SSM’s scientific council on ionizing radiation within oncology, 2010
this report, three main areas have been highlighted: quality assurance (QA), quality control (QC) and late side-effects including the risk of radiation-induced secondary malignancies. These areas reflect ... radiotherapy and intensity-modulated radiotherapy and how these influence QA, QC and late side-effects. Late side-effects of radiotherapy are also discussed in the context of paediatric oncology and radiotherapy...

2011:21 Workshop on spent fuel performance and radionuclide chemistry -Rånäs 2010: Assessment of some outstanding issues
spent nuclear fuel has to comprehensively address the stage when containment barriers have failed and when radionuclide releases occur to the surrounding groundwater at repository depth. Essential processes ... oxidative dissolution of the UO2-matrix, inte- raction between radionu-clides and geologic media as well as secondary phases, and formation of intrinsic actinide colloids. This report descri- bes the outcome...
