• 2017:15 Radionuclide release rates associated with bounding cases featuring relatively early canister failures in a spent fuel repository

  Swedish Radiation Safety Authority (SSM) for five years. During the review SSM commissioned the Southwest Research Institute (SwRI) to develop a model independent of SKB’s model to simulate the canister failure ... to isostatic load. SwRI built up the model based on their understanding of SKB’s model description. From SwRI’s modelling it could be confirmed that SKB’s modelling results were relatively consistent with...
