• 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...

• 2017:25 Evaluation of weld fatigue reduction in austenitic stainless steel pipe components

  Background The performed investigation is a continuation of the work performed in SSM 2015:38 where fatigue tests were performed on pressurized welded austenitic stainless steel piping components. The specimens were subjected to a realistic variable amplitude loading with mainly reversed bending deformation and particular focus on high cycle fatigue. The previous fatigue results were quite...

• 2017:11 Extended Common Load Model: A tool for dependent failure modelling in highly redundant structures

  Background The treatment of dependent failures is one of the most controversial subjects in reliability and risk analyses. The difficulties are specially underlined in the case of highly redundant systems, when the number of redundant components or trains exceeds four. The Common Load Model (CLM), originally defined in the 70’ies, differs from other CCF models, as it relies on a specific...

• Our safety and security work

  The role of the Swedish Radiation Safety Authority is to impose safety and security requirements as well as to conduct follow-ups to ensure that the entities operating the facilities fulfil the applicable regulatory frameworks and requirements.

• Discharges

  The Swedish Radiation Safety Authority sets constraints for discharges of radioactive substances and checks that the operator stays well below these constraints. We also require the nuclear facilities to make use of best available techniques for gradual reduction of discharges.

• Man-Technology-Organisation

  No technical safety systems can work without the close involvement of people and the surrounding organisation. This is why our regulatory supervision is based on how people work and the fact that quality and safety hinge on people, the specific context and organisation, alongside the technology itself. We always have this perspective when we review all aspects of nuclear power plant...

• 1992:3 Characterization of seismic ground motions for probabilistic safety analyses of nuclear facilities in Sweden. SUMMARY REPORT

  In Scandinavia seismic activity is generally low. Only a few incidents have been registered in historic time, which might have damaged an industrial plant of today. The risk of a nuclear accident in Sweden, caused by an earthquake, may thus be considered to be low. The two latest reactors Forsmark 3 and Oskarshamn 3 have been analysed and designed to resist a specified earthquake. For the...

• 2014:43 Technical Note, Workshop on general corrosion of copper

  This report describes the outcome of the workshop organized by SSM on general corrosion of copper that was held in Stockholm on the 26-27th of August, 2013. The report summarizes the issues discussed and extracts the essential viewpoints that have been expressed. It should not be considered as a comprehensive record of all the discussions at the workshop and individual statements made by...
