2012:44 Technical Note, Review of Matrix Diffusion and related properties of intact rock in SKB’s Licence Application for a Spent Nuclear Fuel Repository in Forsmark, Sweden
This report summarizes a review of SKB’s theoretical development of matrix diffusion, its associated processes and parameters, and the data supporting calculations of matrix diffusion. In addition to diffusion ... have been some of the most important in the field. Consequently, the process is well understood both theoretically and practically. As a result of extensive field and laboratory testing, the average value...

2014:46 Technical Note, QA in SKB’s Groundwater Flow Modelling
provide review comments on SKB’s postclosure safety analysis, SR-Site, for the proposed repository at Forsmark. The specific objective is to get an understanding and an assessment of SKB’s quality assurance ... connection to SR-Site. The reliability of the results of the groundwater flow modelling depends inter alia on the quality assurance, in particular in such a complex modelling work that SKB has performed in connection...

2009:15 Improvement and Validation of Weld Residual Stress Modelling Procedure
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 ... research results in the field of WRS. The major changes applied in the new weld residual stress modelling procedure are: Improved procedure for heat source calibration based on use of analytical solutions...

2005:33 Groundwater Flow and Radionuclide Transport in Fault Zones in Granitic Rock, Chapters 1-2
directly from a detailed fracture map from a site in southern Sweden, and a synthetic geometry based on statistics of maps. For both cases, diffusion into stagnant branches increases retardation of solute ... combined with matrix diffusion. This surprising result is interpreted as due to the interaction of flow-field heterogeneity and through-diffusion across fracture blocks. Where through- diffusion occurs, in some...
