• 2022:13 Long-time variations of radionuclides and metals in the marine environment of the Swedish west-coast studied using brown algae

  The marine environment receives discharges from nuclear facilities around the world as well as in Sweden. The brown seaweeds, Fucus serratus and Fucus vesiculosus, are important organisms in the marine ... usefulness in environmental monitoring as a bio indicator. Bio indicators provide information on levels and variations of elements, like for example radionuclides, in the marine environment. By studying...

• 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, ... Resultaten från mätningarna visade på dragspänningar i nivå med sträckgränsen i pläteringen och cirka 30 mm in i grundmaterialet. Efter värmebehandling konstaterades kraftigt reducerade spänningar i grundmaterialet...

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

  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 ... as terrestrial data from a glacial morphological mapping campaign. A broad range of landforms could be observed in these data and the overall glacial morphology pointed towards a powerful glacial impact...

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

  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 ... protons hit the tungsten target. In addition, a broad range of radioactive by-products is produced that differs from the fission products produced in a nuclear reactor. In case of an accident scenario target...
