2018:18 Procedure for Safety Assessment of Components with Defects
– Handbook Edition 5 Background SSM and the Swedish nuclear power plant owners have financed Kiwa Inspecta Technology in Sweden to develop a new version of the handbook for assessment of defects. This ... update of the former fracture mechanics handbook that was published at SSM as Research 2008:01. The procedure in the handbook is based on the British R6-method where the failure mechanisms fracture and plastic...

2021:05 Cladding tube rupture under LOCA: Data and models for rupture opening size
SSM perspective Background The Swedish Radiation Safety Authority (SSM) follows the research on fuel performance closely. One aspect that is currently being studied in several research projects is the ... risk of release of fragmented fuel into the primary coolant in case of an accident. This risk depends on complex conditions were one is the possibility and size of a rupture of the fuel rod cladding tube...

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...

2017:02 Slow strain rate testing of copper in sulfide rich chloride containing deoxygenated water at 90 °C
conducted to a certain level of strain where after presence of cracking on the specimen surface were evaluated. Results Based on the results in this study, SCC in oxygen free copper material intended for ... threshold value of approximately 160 MPa. At lower sulfide concentration (~1·10−4 M), no SCC was observed on specimens. To some degree these results are consistent with other results found in the literature,...

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...

2021:09 Mechanisms important for material modelling in weld residual stress analysis
SSM perspective Background The prediction of weld residual stresses (WRS) is very complex as many mechanisms and phenomena influence the development of WRS during welding. For accurate prediction, the ... weldment constituents. For example, selection of a material model should only depend on material behaviour and not on other parameters, mechanisms or modelling techniques. Thus, before constitutive models...

2023:03 A novel method for retrospective analysis regarding appropriateness of radiological examinations
SSM perspective Background The use of X-ray diagnostic examinations, especially computed tomography, has increased in recent decades and it is essential that this increase is justified and contribute to ... particular importance for medical exposures because dose limits for this type of exposure are exempt. SSM perspective Background The use of X-ray diagnostic examinations, especially computed tomography, has...

2016:28 Fatigue fracture surface characterization and investigation
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 examine ... increased the understanding of fatigue critical points in welds, as well as it has increased knowledge on where fatigue cracks initiated and how propagation occur in the welded austenitic stainless steel pipes...
