2010:38 The feasibility of Backfilling a Repository of Spent Fuel: An Assessment of Recent Developments by SKB
In the Review Statement and Evaluation of SKB’s RD & D programme 2007 (SKI Report 2008:48E), the former Swedish Nuclear Power Inspectorate (SKI) commented that considerable work remained to be done for knowledge of both practical management issues on backfilling and analysis of long-term backfill evolution to reach the same level as for the canister and the buffer. SKI considered that the...

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...

2013:09 An Application of the Functional Resonance Analysis Method (FRAM) to Risk Assessment of Organisational Change
The objective of this study was to demonstrate an alternative approach to risk assessment of organisational changes, based on the principles of resilience engineering. The approach in question was the Functional Resonance Analysis Method (FRAM). Whereas established approaches focus on risks coming from failure or malfunctioning of components, alone or in combination, resilience engineering...

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...

2013:27 Numerical simulations of headed anchors break in reinforced and non-reinforced concrete structures
The design codes for anchorage of equipment in concrete structures have been developed since the time the Swedish power plants were designed. Furthermore, the design basis has been updated and in some cases new mechanical loads have been added. As a consequence, it can be difficult for some anchorages to meet the requirements of today. In the design of anchorage equipment the beneficial effect...

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...

2014:52 Beständiga förändringar av säkerhetskulturen
Projektet har genomförts dels som en litteraturstudie och dels som en intervjuserie vid svenska kärnkraftverk. Litteraturstudien resulterade i en beskrivning av viktiga komponenter inom området säkerhetskultur, faktorer som anses möjliggöra eller förhindra att en god säkerhetskultur uppnås samt metoder och arbetssätt för att utveckla och förbättra...

2014:28 Numerical simulation of ductile crack growth in residual stress fields
The study has shown on the capability of the cell model in capturing the effects on ductile tearing from limited pre-load levels and a residual stress field. Some of the conclusions are as follows: No distinctive influence on the material fracture toughness is observed from pre-loading (work hardening), both tensile and compressive, at room temperature of 1.5 or 3 % total strain. The cell...

2015:04 DiD-PSA: Development of a Framework for Evaluation of the Defence-in-Depth with PSA
The project declares an interpretation of the definitions of Defence in Depth given by IAEA which outline a framework to meet PSA. For each level of defence and combinations of levels, methods to give estimates from a PSA perspective are presented and discussed. One important result is the discussion of the basic definitions and the basis for defence-in-depth, as defined by IAEA, leading to...
