2010:43 Displacement along extensive deformation zones at the two SKB sites: Forsmark and Laxemar
Precambrian denudation surface; the sub-Cambrian peneplain. Palaeozoic and younger sediments were deposited on the peneplain, but these sediments have been removed from most areas that now form the mainland of ... used in this report to complement the structural observations made at sites located on the mainland, giving information on displacement along faults. For construction of a geological repository for disposal...

2016:27 Validation of fatigue fracture mechanics approaches
Background In a previous study (SSM research report 2015:38) fatigue experiments were performed on welded austenitic stainless steel piping components. The fatigue experiments offer an opportunity to evaluate ... evaluate fatigue flaw tolerance assessments used in industry, which are based on the fracture mechanical approach implemented in ProSACC. Objective The present study aims to validate the used fatigue flaw...

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...

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...

2017:19 Numerical simulations of headed anchors break in reinforced and non-reinforced concrete structures, Phase 2
ASCI 349-06 code opens up 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 ... fill this gap. Inspecta Nuclear AB and Scanscot Technology AB have, in a previous work funded by SSM (SSM 2013: 27), studied the possibility to transfer mechanical loads from embedded anchors to the concrete...
