• 2009:26 Tillämpning av stabil spricktillväxt vid brottmekanisk bedömning av defekter i sega material

  Vid brottmekaniska analyser studeras i huvudsak haverimekanismerna sprött brott och plastisk kollaps samt kombinationen av dessa. Den styrande mekanismen bestäms av komponentens materialegenskaper, styrande belastning och defektens geometri. Proceduren enligt SKI-rapport 99:49 är idag en av de mest använda metoderna vid brottmekaniska analyser. Proceduren som baseras på...

• 2009:25 APRI-6 Accident Phenomenaof Risk Importance

  Kunskap om de fenomen som kan uppträda vid svåra haverier i en kärnkraftanläggning är viktig förutsättning för att kunna förutse anläggningens beteende, för att kunna utforma rutiner och instruktioner för haverihantering, för beredskapsplaneringen samt för att få god kvalitet på haverianalyser och riskstudier. De svenska...

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

  Weld residual 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 arrive at proper conclusions when assessing detected flaws, for inspection planning and for assessment of leak-before-break margins. The fracture mechanical treatment of weld...

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

  The regulator 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 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...

• 2009:14 Review of Legislation and Regulatory Framework in Ukraine with Regard to Environmental Radiation Monitoring

  This report was written in the frames of the development cooperation project in Ukraine entitled “Environmental Radiation Monitoring”. This report concerns a study which has been conducted for the Swedish Radiation Safety Authority, SSM. The conclusions and viewpoints presented in the report are those of the author/authors and do not necessarily coincide with those of the SSM. In 2006, the...

• 2009:21 The geological history of the Baltic Sea a review of the literature and investigation tools

  The bedrock in Sweden mainly comprises Proterozoic magmatic and metamorphic rocks older than a billion or one and a half billion years with few easily distinguished testimonies for the younger history. For construction of a geological repository for deposition of nuclear waste it is important to understand the late, brittle, geological events to be able to estimate its influence and...

• 2009:33 Workshop on spent fuel performance, radionuclide chemistry and geosphere transport parameters, Lidingö 2008: Overview and evaluation of recent SKB procedures

  The safety assessment for disposal of spent nuclear fuel canister in the Swedish bedrock should thoroughly address the time period after a containment failure. Such a failure could be expected as a result of corrosion damage or mechanical failure due to rock movement. This report mainly covers some issues connected to parameters used for radionuclide transport calculations in the areas of...

• 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 be caused by UVB radiation. However, recent studies show that UVA and UVB can give rise to similar DNA damages in human skin. Because of the potentially greater exposure to UVA while using...

• 2009:22 Alternative modelling of brittle structures in a sub-area of the SKB candidate area at Forsmark, eastern Sweden

  A reasonable understanding of the character of the bedrock hosting a deep geological repository, i.e. the natural barrier, is an important component in the safety assessment of the deep geological repository for spent nuclear fuel. The structures in the rock, together with the regional stress field, affect the mechanical stability of the bedrock and the ground water transport within the...
