2021:09 Mechanisms important for material modelling in weld residual stress analysis
SSM perspective Background The prediction of weld residual stresses (WRS) is very complex as many mechanisms and phenomena influence the development of WRS during welding. For accurate prediction, the constitutive material models used are essential and must be able to describe the material response of the weldment constituents. For example, selection of a material model should only depend on...

2021:10 Establishment and use of attention values in environmental fatigue assessments
SSM perspective Background As Swedish NPPs reach their original technical design life, re-assessment of the fatigue life of structural components is needed for safe long term operation (LTO). In these re-assessments one must consider that new knowledge has shown that environmental effects on fatigue life must be considered. One common method to verify the fatigue life of structural components...

2021:17 Inverkan från undergrund och bränslebassänger vid jordbävningsanalyser på svenska kokvattenreaktorer
SSM perspektiv Bakgrund Vattnet i en bassäng, såsom bränsle- och kondensationsbassänger i kärnkraftsreaktorer, har en stor inverkan på strukturens verkningssätt när en sådan konstruktion blir utsatt för seismiska laster. Vattnet bidrar med en ökad massa som sänker strukturens egenfrekvenser och dessutom ger det upphov till hydrostatiskt...

2021:20 Effects of additives on UO2 fuel behavior: expanded edition
SSM perspective Background The Swedish Radiation Safety Authority (SSM) follows the development of nuclear fuel closely. Fuel with additives like chromia and gadolinia is used in Swedish reactors and fuel with even better thermal and mechanical properties is under development. This project is an in-depth study of data and models regarding the impact of additives on the properties of uranium...

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...

2022:16 Recent Research o EMF and Health Risk, Sixteenth report from SSM’s Scientific Council on Electromagnetic Fields, 2021
SSM perspective Background The Swedish Radiation Safety Authority’s (SSM) Scientific Council on Electromagnetic Fields monitors current research on potential health risks in relation to exposure to electromagnetic fields and provides the authority with advice on assessing possible health risks. The Council gives guidance when the authority must give an opinion on policy matters when...

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...

2022:02 APRI-10 - Slutrapport
SSM perspektiv Bakgrund Strålsäkerhetsmyndigheten (SSM) har sedan början på 1990- talet finansierat forskning inom svåra haverier, då dåvarande SKI finansiellt bidrog till en professur och utvecklandet av avdelningen för kärnkraftsäkerhet på KTH. Inriktningen har varit att studera och verifiera den svenska haverihanteringen vid svårt...
