• 2023:03 A novel method for retrospective analysis regarding appropriateness of radiological examinations

  SSM perspective Background The use of X-ray diagnostic examinations, especially computed tomography, has increased in recent decades and it is essential that this increase is justified and contribute to a better care of the patients. There are many reasons to refrain from performing inappropriate radiological examinations, including not to expose patients to unnecessary ionising radiation. In...

• 2023:02 Investigation of risk assessment for decommissioning waste to Fortum’s landfill at Norrtorp

  SSM perspektiv Bakgrund I och med avveckling och rivning av ett flertal kärnkraftsreaktorer i Sverige har Strålsäkerhetsmyndigheten identifierat att ansökningar om dispens, så kallad riktad friklassning, för att deponera lågaktivt avfall (VLLW) kan komma att öka. En avfallsdeponi som tagit emot ett flertal omgångar med avfall från riktade friklassningar...

• 2022:18 Data report – sampling of sea water and marine organisms outside Ringhals NPP

  SSM perspective Background The Radiation Safety Authority (SSM) funded the collection of marine biota over an annual cycle at the Ringhals nuclear power plant (NPP) to enable development of analytical methods for C-14. Methods for the C-14 analysis and results in the form of levels of C-14 in various marine organisms have been reported by the Swedish Defense Research Institute (FOI) in FOI...

• 2022:14 Weld residual stress and strain measurements on a mock-up with single layer strip cladding common in reactor pressure vessels

  SSM perspektiv Bakgrund Reaktortryckkärl tillverkas vanligtvis av låglegerade ferritiska stål som på insidan beläggs med ett eller flera lager av rostfritt stål, så kallad plätering eller på engelska cladding. Den rostfria pläteringen påverkar den strukturella integriteten på flera sätt, dels har pläteringen annorlunda materialegenskaper...

• 2022:10 Internal dosimetry of radionuclides that can be released during an accident at the European Spallation Source (ESS)

  Läs mer SSM perspective Background To strengthen the material science research in Europe, the European Spallation Source (ESS) is being built in Lund in the southern part of Sweden. In the spallation process, neutrons are generated when the accelerated protons hit the tungsten target. In addition, a broad range of radioactive by-products is produced that differs from the fission products...

• 2022:09 Assessment of modelling approaches for axial gas flow inside LWR fuel rods

  SSM perspective Background The fuel rod analysis program SCANAIR has been developed by IRSN (Institut de Radioprotection et de Sûreté Nucléaire) for analysis of reactivity initiated accidents (RIA) in light water reactors. The Swedish Radiation Safety Authority (SSM) has access to SCANAIR in exchange for annual contributions for its further development. The development...

• 2022:08 Geophysical surveys on sub marine land- and rock slides and on alpine glaciers

  SSM perspective Background The future climate evolution and the impact it might have on a repository for radioactive waste is important when assessing the long-term safety. In a project funded by SSM (Holmlund et al. 2016), bathymetric data from the Southern Quark area between Sweden and Åland, provided by the Swedish Maritime Administration, were analysed, as well as terrestrial data from...
