02:03 Natural Elemental Concentrations and Fluxes: Their Use as Indicators of Repository Safety (pdf 1,30 MB)
mainly due to the unavoidable uncertainties in predicting human behaviour and biosphere evolution. On the other hand, the confidence in calculated values of radionuclide flux from a repository and the ... concentrations or fluxes could be based on model calculations for a suitable set of standard biospheres. The most obvious choice of target values, however, would be based on natural concentrations and fluxes...

2017:11 Extended Common Load Model: A tool for dependent failure modelling in highly redundant structures
Common Load Model (CLM), originally defined in the 70’ies, differs from other CCF models, as it relies on a specific physical analogy. The model was extended in late 80’ies with specific aims to model highly ... before. However, it has been developed with certain funding via the Nordic PSA group (NPSAG) including SSM. It has therefore been an interest to have the method properly documented and published. The objective...

2020:16 Estimates ofJ-integral and COD for circumferential through wall cracks under global bending including the effect of pipe end restraint
SSM perspective Background Leak-before-break (LBB) piping assessments have shown that piping systems can withstand long through-wall cracks before pipe rupture is expected. This is somewhat because pipe ... investigate what impacts the assumption degree of restraint at the ends of an analysed piping segment have on leak-before-break assessments and leakage rate calculations. Results The study conclude that crack...
