• 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...

• 2012:01 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...

• 2011:19 Experimental evaluation of influence from residual stresses on crack initiation and ductile crack growth at high primary loads

  Cracked components are usually subjected to loads causing both primary and secondary stresses, e.g. welding components. Engineering assessment approaches, such as the ASME XI code and the R6 procedure, are commonly used to conduct integrity assessment of such components. There has been an ongoing debate how to treat secondary stresses using engineering assessment methods. The nature of these...

• 2011:29 Research and Development Program in Reactor Diagnostics and Monitoring with Neutron Noise Methods, Stage 17

  This report constitutes Stage 17 of a long-term research and development program concerning the development of diagnostics and monitoring methods for nuclear reactors. Results up to Stage 16 were reported in SKI and SSM reports, as listed below and in the Summary. The results have also been published in international journals and have been included in both licentiate- and doctor’s degrees.

• 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...

• 2011:33 Mathematical modelling of ultrasonic testing of components with defects close to a non-planar surface

  The report describes work that has been performed in order to model ultrasonic testing of components that contain a defect close to a non-planar surface. The studies have been performed in both 2D and 3D, and in 2D in both the anti-plane (SH) and the in-plane (P-SV). The results show that the presence of a non-planar back wall can reduce the detectability of defects close to the surface. The...

• 2010:41 Rock-block configuration in Uppland and the Ålands-hav basin, the regional surroundings of the SKB site in Forsmark, Sea and land areas, eastern Sweden

  This report concerns a study which was initially conducted for the Swedish Nuclear Power Inspectorate (SKI), which is now merged into the Swedish Radiation Safety Authority (SSM). The conclusions and viewpoints presented in the report are those of the authors and do not necessarily coincide with those of the SSM. The topography in Uppland is more broken in the sea area east and northeast of...

• 2010:32 Fingerprints of zones in boreholes An approach to identify the characteristics of structures

  This report concerns a study which was initially conducted for the Swedish Nuclear Power Inspectorate (SKI), which is now merged into the Swedish Radiation Safety Authority (SSM). The conclusions and viewpoints presented in the report are those of the authors and do not necessarily coincide with those of the SSM. The Swedish Nuclear Fuel and Waste Management Co (SKB) has published Site...

• 2010:40 Rock-block characterization on regional to local scales for two SKB sites in Forsmark – Uppland and Laxemar – eastern Småland, south-eastern Sweden

  To get an overall impression of the general structural setting of a landscape, a remote study of bedrock structures should include studies of the geomorphology at various scales. Thematic maps improve the general understanding of an area. Digital elevation data in 500m, 50m and 10m grids were used for rock-block interpretations at regional, semi-regional and local scales of areas around the...
