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...

2022:02 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...

2022:04 Warm Pre-Stressing mechanisms
SSM perspective Background Swedish nuclear power plants (NPP) were originally designed and analyzed with an assumed operating period of approximately 40 years. As Swedish NPPs reach their original technical design life the safety of the additional operating time has to be verified. With increased operating time, the shift in the fracture toughness curve of the reactor pressure vessel (RPV)...

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 and administration...

2017:01 Stabilitet och flexibilitet i ledningssystem
Bakgrund Strålsäkerhetsmyndigheten (SSM) ställer krav på att kärnteknisk verksamhet ska ledas, styras, utvärderas och utvecklas med stöd av ett ledningssystem som är utformat så att kraven på säkerhet uppfylls. Ledningssystemet, inklusive tillhörande rutiner och instruktioner, ska hållas aktuellt och vara dokumenterat. SSM ställer...

2017:19 Numerical simulations of headed anchors break in reinforced and non-reinforced concrete structures, Phase 2
Background In the design of anchorage equipment in concrete structures the beneficial effects of reinforcement are, in most cases, not considered. The American ASCI 349-06 code opens up for a more detailed analysis where the beneficial impact of reinforcement on anchor capacity can be taken into account. How this analysis can be done is, however, not explicitly described in the code. The...

2017:34 Human capability to cope with unexpected events
Background In the light of the Fukushima accident, it stood clear that the challenge of the unexpected is of great importance to both regulators and licensees. For SSM, as for many other national regulators, there was a selfevident need to learn more about the capabilities and actions of people when the unexpected arises and conditions are potentially extreme. A task group was set up within...
