  • 2010:16 Guidance to Risk-Informed Evaluation of Technical Specifications using PSA

    No guidance documents for risk-informed analysis and assessment of changes in Limiting Conditions for Operation (LCO:s) in TS (Technical Specifications) have been available in the Nordic countries. In the U.S. several guidance documents, primarily developed by the owners groups for PWRs and BWRs, exist. Guidance for analysis of TS changes in this report generally follows the U.S. Regulatory...

  • 2010:39 Beskrivning av Eurokoder för betongkonstruktioner

    Eurokoder, som är gemensamma europeiska standarder för utformning och dimensionering av bärande konstruktioner till byggnader och anläggningar, utarbetas av den Europeiska Standardiseringskommittén (CEN) och ges i Sverige ut av det svenska institutet för standarder (SIS). Sverige, liksom de andra CEN-medlemsländerna, är i färd med att ersätta sina...

  • 2009:27 Analysis Strategy for Fracture Assessment of Defects in Ductile Materials

    SSM has supported research for investigating the role of secondary stresses when fracture assessments are performed for cracked structures made of ductile materials. There are evidences that indicate that some secondary stresses, such as weld residual stresses, are not as important as primary stresses for estimating the safety margin against rupture (measured by the J-integral) for the type...

  • 2010:03 Forskningsstrategi 2010-2014

    Strålsäkerhetsmyndighetens uppdrag omfattar frågor om skydd av människors hälsa och miljön mot skadlig verkan av joniserande och icke-joniserande strålning, säkerhet i kärnteknisk verksamhet samt nukleär icke-spridning. För att myndigheten ska kunna utföra uppdraget behöver ny kunskap kontinuerligt tillföras verksamheten. Genom...

  • 2005:61 Review and Assessment of SCC Experiments with RPV Steels in Oskarshamn 2 and 3 (ABB Report SBR 99-020)

    Although the extent of cracking was rather surprising for a bolt-loaded specimen, the average stress corrosion crack growth rate of 0.5 mm/year over the five-year testing period does not represent an immediate concern. The overwhelming part of crack growth can have occurred during a 20 day chloride transient during the third year of exposure because of a condenser leakage after an outage. The...

  • 1997:40 Aging of Electrical Components in Nuclear Power Plants

    The purpose of the study reported in SKl Technical Report 93:39 was to evaluate qualification methods for application to components intended to be installed in the containment of nuclear power plants. The study included application of Arrhenius' criterion for thermal aging as well as methodologies for updating (curve-matching, ongoing qualification). This report reviews the results of...

  • 1997:12 Study of International Published Experiences in Joining Copper and Copper-alloys

    This study has revealed a number of joining processes to be used when manufacturing copper-canisters for the final storage of high level nuclear waste. However, the decision on which material and which joining process to be used has to be based on the design criterions. The welding procedure has to be qualified i.e, it shall be demonstrated whether the procedure is capable of fulfilling...

  • 96:40 Status and Use of PSA in Sweden

    The performance and use of PSA:s in Sweden goes back about two decades. During all of this time, the field of PSA has been developing intensively, both internationally and within Sweden. The latest years have been characterised by an increased use of PSA models and results, and by major extensions of existing PSA models. The aim of this document is to describe PSA in Sweden with respect to...

  • 1995:72 Kopparkorrosion i rent syrefritt vatten

    Kopparkorrosion i rent vatten har studerats. Undersökningen är bl a föranledd av artiklar publicerade i Corrosion Science. I dessa artiklar presenterades resultat som visar att koppar kan korrodera i rent vatten i frånvaro av löst syrgas. Koppar oxideras i stället direkt av vattnet under bildning av vätgas. Kvartsprovrör innehållande rent vatten och...
