2010:12 An Evaluation of Models of Bentonite Pore Water Evolution
implication of such bentonite chemical reaction is that radionuclide solubility and sorption depend on the buffer chemical conditions. Moreover, pore-fluid composition at the interface between the buffer ... bentonite buffer. In the more traditional buffer geochemical modelling approach, the focus has been on more reactive trace constituents such as calcite, gypsum and pyrite, but the potential bulk-transformation...

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.

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...
