2011:30 A fatigue analysis including environmental effects for a pipe system in a Swedish BWR
The effect of the environment on fatigue design has been the subject of intense study in USA, Japan and elsewhere. Several reports indicate a potentially large influence of the environment, leading to ... proposal of entirely new analysis procedures. SSM has in an earlier project sponsored research to evaluate the technical basis for these proposals, see SSM Research Report 2011:04. In the current report...

2017:25 Evaluation of weld fatigue reduction in austenitic stainless steel pipe components
Background The performed investigation is a continuation of the work performed in SSM 2015:38 where fatigue tests were performed on pressurized welded austenitic stainless steel piping components. The specimens ... with mainly reversed bending deformation and particular focus on high cycle fatigue. The previous fatigue results were quite dependent on the estimation of the stress concentration factor of the weld.

2007:41 Dependency Analysis Guidence, Nordic/German Working Group on Common cause Failure analysis Phaase 1 project report: Comparison and application to test cases
The report “Nordic/German Working Group on Common cause Failure analysis. Phase 1 project report: Comparisons and application to test cases” presents a common attempt by the authorities and the utilities ... into a harmonised direction. A next step could be to develop and agree on event & formula driven impact vector creation based on component impairments, time differences and shared cause assessment. Following...

2015:38 Evaluation of fatigue in austenitic stainless steel pipe components
austenitic stainless steel, by performing fatigue experiments on a realistic welded austenitic stainless steel piping component. A particular focus is on high cycle fatigue and variable amplitude loading. The ... survival probability of 95 %. A more detailed evaluation of the extent of the margins will largely depend on the weld fatigue reduction factor for the specific component. The constant amplitude results indicated...

2020:07 Fibre Clogging in Nuclear Power Plants
SSM perspective Background Emergency core cooling systems in boiling- and pressurized water reactors use strainers. Their purpose is to out foreign material suspended in the cooling water so this material ... increased the surface size of the strainers, to avoid them from being clogged. The risk of accumulation on the strainers is increased pressure drop over strainers, potentially causing cavitation in the emergency...
