1994:28 ”SKIFTNYCKELN”
Denna uppsats beskriver utvecklingen av en metod för bedömning och analys av kommunikation och samspel i kontrollrum på ett kärnkraftverk. Utifrån en övergripande litteraturgenomgång samt intervjuer med berörd personal vid KSU (Kärnkraft-Säkerhet Utbildning) och Ringhals kärnkraftverk konstruerades ett verktyg anpassat för utvärdering...

1994:14 Evaluation of acceptance criteriafor data on environmentally assistedcracking in light water reactors
The assessment of possible sub-critical crack growth through environmentally assisted cracking (EAC) is a commonly encountered problem in safety evaluations of light water reactor components. The numerous factors influencing EAC fall into three main groups (material, medium and loading), but their interactions are highly complex. Field assessments usually rely on the evaluation of...

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...

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...

2017:08 Konsekvenser av instruktioners utformning och användning
Bakgrund Inom säkerhetskritiska branscher används ofta ett instruktionsstyrt arbetssätt i hög utsträckning. Miljön i sig och de eventuella risker som kan finnas inom verksamheten man befinner sig i kan leda till att man vill föreskriva exakt hur och när arbete ska genomföras. Detta anses skapa bland annat trygghet, förutsägbarhet och stabilitet.

2010:41 Rock-block configuration in Uppland and the Ålands-hav basin, the regional surroundings of the SKB site in Forsmark, Sea and land areas, eastern Sweden
This report concerns a study which was initially conducted for the Swedish Nuclear Power Inspectorate (SKI), which is now merged into the Swedish Radiation Safety Authority (SSM). The conclusions and viewpoints presented in the report are those of the authors and do not necessarily coincide with those of the SSM. The topography in Uppland is more broken in the sea area east and northeast of...
