2012:21 Technical Note, Initial Review Phase for SKBs Safety Assessment SR-Site: Corrosion of Copper
models for spontaneous uniform corrosion rates are non-conservative as currently composed and rely on key tenets that create low rates. Either evidence supporting these key tenets and assumptions should ... HS- consumption (perhaps catalyzed by S-2 regeneration and re-adsorption). This assumption of HS- sequestering could be strengthened. J.R. Scully and T.W. Hicks SSM English The uniform and localized corrosion...

2011:20 A Guidebook for Evaluating Organizations in the Nuclear Industry – an example of safety culture evaluation
Organizations in the nuclear industry need to maintain an overview on their vulnerabilities and strengths with respect to safety. Systematic periodical self- assessments are necessary to achieve this overview ... system safety. The validity and credibility of the evaluation stem largely from the evaluation team‟s ability to crystallize what they mean by organization and safety when they conduct organisational safety...

2011:12 Analysis of Barrier Performance: Modelling of Copper corrosion scenarios with and without buffer erosion
(intersecting deposition holes) and local SRB activity all contributes to an uneven corrosion profile on the canister. This is not caused by a true localized corrosion phenomenon but rather by what might ... formulation of SRB activity suggests only a moderate influence on copper corrosion. Steven J. Benbow, Peter C. Robinson and Sarah P. Watson SSM English The purpose of this project was to develop a numerical...

2014:32 Technical Note, Assessment of the derivation and use of distribution coefficients and concentration ratios – Main Review Phase
The method applied by SKB to derive the CR and Kd values are based on a Bayesian approach that combines literature values with in-situ, on site data. Whilst the numbers of site data were often limited the ... account results below the limits of detection. Nicholas Beresford, Patrick Boyer and Brenda Howard SSM English This report presents a review of the approaches and databases which SKB have used to derive...

2013:27 Numerical simulations of headed anchors break in reinforced and non-reinforced concrete structures
349-06 code open up today for a more detailed analysis where the beneficial impact of reinforcement on anchor capacity can be taken into account. How this analysis can be done is, however, not explicitly ... sufficient reinforcement is present. The objective of the project is to study the effect of reinforcement on the concrete breakout capacity of cast in headed bolts in concrete structures by numerical simulations...
