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...

2018:01 Monte Carlo patient-specific pre-treatment QA system for volumetric modulated arc therapy
Background According to the Swedish Radiation Safety Authority's Regulations in Radiotherapy (SSMFS 2008:33) are Swedish clinics required to verify the individual dose to patients, prior the first time ... three dimensional conformal radiation therapy (3DCRT), which means that the entrance of each patient field is measured with a diode in a specific point and compared to the calculated dose in the same point...

2009:35 Evaluation of SKB/Posiva’s report on the horizontal alternative of the KBS-3 method
The KBS-3 method, based on multiple barriers, is the proposed spent fuel disposal method both in Sweden and Finland. The method has two design alternatives: the vertical (KBS-3V) and the horizontal (KBS-3H) ... Authority (SSM) considers that it is a proper time to evaluate the work carried by SKB and Posiva when this period of joint research is ended and a relatively complete set of reporting is available. SSM therefore...
