• 2009:12 Evaluating safety-critical organizations – emphasis on the nuclear industry

  identified a few years ago a need for a better understanding of and a deeper knowledge on methods for evaluating safety critical organisations. There is a need for solid assessment methods in the process ... process of management of organisational changes as well as in continuously performed assessment of organisations such as nuclear power plants. A considerable body of literature exists concerning assessment...

• 2009:17 Effect of Welding Residual Stresses on Crack Opening Displacement and Crack-Tip Parameters

  stresses have a large influence on the behavior of cracks growing under normal operation loads and on the leakage-flow from a through-wall crack. Accurate prediction of these events is important in order to ... detected flaws, for inspection planning and for assessment of leak-before-break margins. The fracture mechanical treatment of weld residual stresses in commonly used engineering assessment methods generally...

• 2009:32 On Younger Stakeholders and Decommissioning of Nuclear Facilities

  appropriate balance in this regard must be based on a proper understanding of the values and value functions of younger citizens. Such information must thus be an integral part of the knowledge base to ... decommissioning of nuclear power plants and other older nuclear facilities. In the present project, empirical data have been collected and compiled in a survey of the values of younger citizens with regard to...

• 2009:19 Review of SKB’s Quality Assurance Programme

  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 ... 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 there is a satisfactory...

• 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 ... estimating the safety margin against rupture (measured by the J-integral) for the type of ductile materials which can be found in nuclear power plants. : Peter Dillström, Magnus Andersson, Iradj Sattari-Far and...

• 2009:35 Evaluation of SKB/Posiva’s report on the horizontal alternative of the KBS-3 method

  spent fuel disposal method both in Sweden and Finland. The method has two design alternatives: the vertical (KBS-3V) and the horizontal (KBS-3H). SKB and Posiva have conducted a joint research, development ... development and demonstration (RD&D) programme in 2002-2007 with the overall aim of establishing whether the KBS-3H represents a feasible alternative to the reference alternative KBS-3V. The objectives have been...

• 2009:24 UV-radiation induced disease – roles of UVA and UVB

  There is a large uncertainty concerning the impact of UVA and UVB radiation on the skin and eye. For example, UVA radiation used to be considered low risk since it was believed that DNA damage could only ... DNA damages in human skin. Because of the potentially greater exposure to UVA while using sunbeds or UVB-blocking sunscreens, further information on the role of UVA is crucial. It constitutes a necessary...

• 2009:09 Analysis of three sets of SWIW tracer test data using a two-population complex fracture model for matrix diffusion and sorption

  For the non-sorbing tracer uranine, both the finite and the semi-infinite populations play a distinct role in controlling BTC. For the sorbing tracers Cs and Rb the finite population does not saturate ... acts essentially semi-infinite, thus the BTC behaviour is comparable to that obtained for a model containing only a semi-infinite rock matrix. The ability to match BTC for both sorbing and non-sorbing tracers...

• 2009:07 Dependency Analysis Guidance Nordic/German Working Group on Common Cause Failure analysis

  Code SSMFS 2008:1 of Swedish Radiation Safety Authority (SSM) includes requirements regarding the performance of probabilistic safety assessments (PSA), as well as PSA activities in general. Therefore ... the follow-up of these activities is part of the inspection tasks of SSM. According to the SSMFS 2008:1, the safety analyses shall be based on a systematic identification and evaluation of such events,...
