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...
