• 2012:27 Mental arbetsbelastning En fallstudie från projektorganisationen på ett svenskt kärnkraftverk

  Den genomförda studien har fokuserat på den personal som arbetar inom projektorganisationen och är en intervjustudie för att kartlägga den mentala arbetsbelastningen och de risker som finns relaterade till denna. Vidare har studien endast omfattat ett svenskt kärnkraftverk, som därmed får illustrera de faktorer som kan bidra och bidrar till den mentala arbetsbelastningen...

• 2012:50 Fatigue Margins for Austenitic Stainless Steels in ASME Boiler and Pressure Vessel Code – A Literature Study

  Knowledge about the margins against fatigue failure in nuclear piping systems is essential. Therefore, the margins in the ASME Boiler and Pressure Vessel Code (section III) fatigue design procedure for austenitic steels, type 304/316, as applied to real components have been investigated in this literature study. It is concluded that the current knowledge about the margins in ASME for...

• 2012:01 Kontrollrumskonstruktion – Samverkan mellan olika aktörer under konstruktion av nya och moderniserade kontrollrum

  SSM har under senare år ställt högre krav på konstruktion och utformning av kärnkrafts-anläggningarna. Detta tillsammans med kärnkraftsindustrins uppgraderingar av effekten har medfört ett stort antal anläggningsändringar. En del av dessa anläggningsändringar har påverkan på kontrollrum och manöverutrustning samt på...

• 2012:16 El och kontrollutrustning i kärnkraftverk. Problematik vid utbyte av åldrad utrustning

  Studien visar på ett flertal områden som bör beaktas både hos tillståndshavarna och för framtida tillsynsstrategier för SSM. Flera av områdena har betydelse för säkerheten. Till exempel så framgår att konstruktionsprocessens efterlevnad och genomförande är mycket viktig för säkerheten. Genom att el- och kontrollutrustningen...

• 2012:70 Process Parameters Affecting Inhomogeneity of Material Microstructure

  There’s been a tremendous change in the number, product types, locations, equipment, and manufacturing capabilities of stainless steel producers from the late 1960’s to present. This reconfiguration of the global steel industry occurred between the early 1970’s to the mid 1980’s and continues today. These changes have produced a loss in manufacturing flexibility, due to the inherent...

• 2012:07 Implementation of the Master Curve method in ProSACC

  Cleavage fracture toughness data display normally large amount of statistical scatter in the transition region. The cleavage toughness data in this region is specimen size-dependent, and should be treated statistically rather than deterministically. The Master Curve (MC) methodology is a procedure for mechanical testing and statistical analysis of fracture toughness of ferritic steels in the...

• 2012:03 The IAEA Integrated Regulatory Review Service Mission to Sweden in February 2012

  The Swedish Government decided on January 22, 2009 to mandate the Swedish Radiation Safety Authority, SSM, to apply for an international review of the Author-ity and its areas of supervision, an ‘IRRS’ (Integrated Regulatory Review Service) carried out by the International Atomic Energy Agency (IAEA). On February 25, 2009, SSM made a formal request to the IAEA for an IRRS in Sweden. The time...

• 2012:18 Technical Note, SR-Site Independent Modelling of Engineered Barrier Evolution and Coupled THMC: Contribution to the Initial Review Phase

  This review has focussed mainly on the modelling of the Engineered Barrier System (EBS) evolution, which includes coupled thermal, hydraulic, mechanical and chemical (THMC) processes. Additionally, the role of the EBS in the wider safety case was reviewed, including its treatment in scenarios and its representation in conceptual models since this provided the motivation for the modelling work...

• 2012:33 Technical Note, Review of Groundwater Chemistry in SKB’s Safety Assessment SR-Site

  This initial review examined SKB’s characterization of groundwater chemistry at the Forsmark site and its evolution during long time periods under different possible climates in the future. The review considered whether the geochemical data provided by SKB are reasonable and sufficient and whether the methods used by SKB for projecting geochemical conditions into the future are appropriate.

• 2012:11 Issues in the corrosion of copper in a Swedish high level nuclear waste repository

  The objective with this research project was to increase knowledge in the area of copper corrosion in the planned repository environment and obtain information on how copper corrosion evolves during the assessment period of 100 000 years. The equilibrium chemical composition of groundwater close to the canister as a function of temperature has been calculated by use of a thermodynamics code...
