2013:16 Technical Note, Assessment of PWR fuel depletion and of neutron multiplication factors for intact PWR fuel copper canisters – main review phase
the influence of reactor depletion on keff of intact PWR fuel in an intact PWR copper canister flooded with water. The review has, as far as possible, been based on general information in the licensing ... The review method validation is primarily based on keff and reactivity benchmarks rather on composition benchmarks as used by SKB. Dennis Mennerdahl SSM English SKB (Svensk Kärnbränslehantering AB) in...

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...

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...

2022:13 Long-time variations of radionuclides and metals in the marine environment of the Swedish west-coast studied using brown algae
(Fucus serratus and Fucus vesiculosus) SSM perspective Background The marine environment receives discharges from nuclear facilities around the world as well as in Sweden. The brown seaweeds, Fucus serratus ... thereby usefulness in environmental monitoring as a bio indicator. Bio indicators provide information on levels and variations of elements, like for example radionuclides, in the marine environment. By studying...
