• 2017:16 Stress intensity factor solutions for circumferential cracks in cylindrical bars under axisymmetric loading and global bending

  Background The case of a circumferential crack in a cylindrical bar has not been available in the ProSACC code. The need for such a geometry, especially considering nonlinear axisymmetric loading and global bending, has motivated the development of new stress intensity factor solutions, also known as K-solutions. These new K-solutions will be available in ISAAC, the successor to ProSACC.

• 2017:29 Evaluation of the simulation software CIVA for qualification purpose

  Background Modeling is an important tool within NDT, partly to develop and optimize testing technologies, but also within the Qualification Body’s activities to assess technical verifications and perform parameter studies. SSM has supported university research in the area for many years and, among other things, in the development of a software for ultrasound modeling. In addition, the...

• 2017:32 COMRAD – Comprehensive investigation of the performance of computed and digital radiography

  Background Within the industry, there has long been a need to replace the traditional X-ray film and its handling. These both for economic and environmental considerations. Both computed radiography and digital radiography offer many advantages over the traditional use of x-ray with film. However, the transition from film-based radiography requires in-depth knowledge of the relationship...

• Laboratoriearbete med öppna strålkällor

  På många laboratorier inom forskning, veterinärmedicin och industrier används radioaktiva ämnen. Dessa ämnen hanteras ofta öppet i laboratorier på olika sätt. I Strålsäkerhetsmyndighetens föreskrifter kallas detta för arbete med öppna strålkällor.

• 2016:37 PARTRIDGE project: Review and evaluation of the probabilistic fracture mechanics code PRO-LOCA

  Background The Swedish Radiation Safety Authority (SSM) and the Swedish nuclear power plant owners have financed Inspecta Technology in Sweden to evaluate the PRO-LOCA code. It is a computer code, developed by Battelle in the USA, in which the leak- and rupture probabilities of piping in nuclear power plants are analysed. The pipe systems may contain the damage mechanisms fatigue and/or...

• 2017:18 FEM analysis of the mechanical integrity for the canister intended for storage of spent nuclear fuel with regard to copper creep ductility

  Background For final storage of spent nuclear fuel it is suggested by the Swedish nuclear fuel and waste management company (SKB) to emplace the nuclear fuel into copper canisters which are surrounded by bentonite clay at approximately 500 meters’ depth into granitic rock. After emplacement of the canisters Bentonite swelling due to water saturation and hydrostatic pressure build up the...

• 2017:02 Slow strain rate testing of copper in sulfide rich chloride containing deoxygenated water at 90 °C

  Background Stress corrosion cracking (SCC) can occur in materials from the combined influence of tensile stress and a corrosive environment. It has previously been shown in the literature, that copper can be sensitive to SCC in the presence of sulfide containing water. Since both tensile...

• 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.
