• 2010:18 Radionuclide Transport: Preparation During 2009 for the SR-Site Review

  Post-closure safety assessments for nuclear waste repositories involve radioecological modelling for an underground source term. Following several decades of research and development, the Swedish Nuclear Waste Management Company (SKB) is approaching a phase of license application. According to SKB’s plans, an application to construct a geological repository will be submitted by the end of...

• 2010:17 Quality Assurance Review of SKB’s Copper Corrosion Experiments

  SKB is preparing a license application for the construction of a final repository for spent nuclear fuel in Sweden. This application will be supported by the safety assessment SR-Site for the post-closure phase. The assessment of long-term safety is based on a broad range of experimental results from laboratory scale, intermediate scale and up to full scale experiments. It is essential that...

• 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...

• 2010:12 An Evaluation of Models of Bentonite Pore Water Evolution

  The pore-water composition of a KBS-3 bentonite buffer may gradually change as a result of reaction between groundwater and buffer minerals. The rather minor occurrences of the most rapidly reacting minerals in the buffer will have the most immediate and observable influences, but contributions from slow reactions of the main bulk clay phases cannot be ruled out. The performance implication...

• 2010:11 Strålsäkerhetsläget vid de svenska kärnkraftverken 2009

  Enligt Strålsäkerhetsmyndighetens (SSM:s) regleringsbrev ska myndigheten senast den 3 maj 2010 till regeringen redovisa strålsäkerhetsläget vid de svenska kärnkraftverken. Föreliggande rapport utgör denna redovisning. SSM:s samlade bedömning är att strålsäkerhetsläget, dvs. kärnsäkerheten, det fysiska skyddet inkl. kärnämneskontrollen...

• 2010:10 Översikt av nationell och internationell kravbild avseende brandskydd på kärnkraftverk och hur dessa tillämpas i svensk kärnkraftindustri

  De nationella föreskrifterna gällande säkerhet på kärnkraftsanläggningar har historiskt behandlat brandskydd på en mycket övergripande nivå och den gällande kravbilden i tillståndshavares SAR, STF, ledningssystem har utvecklats under lång tid men på ett divergerande sätt. Vissa tillståndshavare har valt att följa internationella...

• 2010:09 Copper Thermodynamics in the Repository Environment up to 130˚C

  The mechanisms of copper corrosion for a KBS-3 repository for spent nuclear fuel need to be known with a high level of confidence. This is because the overall rate of copper canister corrosion (accounting for corroding species concentrations, geochemical conditions and the mass transport through surrounding barriers) provides an essential performance indicator in safety assessment. A...

• 2010:07 Indicators of safety culture – selection and utilization of leading safety performance indicators

  Safety indicators play a role in providing information on organizational performance, motivating people to work on safety and increasing organizational potential for safety. The aim of this report is to provide an overview on leading safety indicators in the domain of nuclear safety. The report explains the distinction between lead and lag indicators and proposes a framework of three types of...

• 2010:06 Upphandling inom kärnkraftsindustrin, kvalitet, säkerhet och beslutsfattande

  Upphandling av tjänster eller annan inhyrd personal eller utrustning såsom byggnadsdelar, komponenter, system är att betrakta som en del av den kärntekniska verksamheten och ska därmed omfattas av ledningssystemet med tillhörande nödvändiga instruktioner (Strålsäkerhetsmyndighetens föreskrifter om säkerhet i kärntekniska anläggningar,...

• 2010:05 Discrete-Feature Model Implementation of SDM-Site Forsmark

  SSM has been following the investigations of the two candidate sites for a repository for spent nuclear fuel that the Swedish Nuclear Fuel and Waste Management Company (SKB) have been undertaking. SKB has reported the results of the investigations as site descriptive models. These models will be used to underpin the safety analysis following the license application of the repository planned...
