2024:18 Modelling Environmental Sensitization of Chromia Forming Nickel Base Alloys Toward Stress Corrosion Cracking in Light Water Reactors by Atomistic Simulations
SSM perspektiv Bakgrund Spänningskorrosion (SCC) i lastbärande konstruktioner har varit en långvarig orosfaktor i både tryckvattenreaktorer och kokvattenreaktorer. Den specifika miljön i kärnkraftstillämpningar består av höga temperaturer och tryck som tillsammans med strålningsfältets inverkan på kylvattnets kemi ger tuffa förhållanden...

2024:17 Atomistic studies on the adsorption and desorption of radionuclides on fuel crud and system surfaces in Light Water Reactors
SSM perspective Background Radiation safety is of particular concern during power plant maintenance. Radionuclides produced by the neutron bombardment in the core during operation may accumulate on system surfaces such as the filter system or piping and contribute to the radiation field. Some ions that are prone to neutron capture often become trapped in the deposits on the fuel cladding...

2024:14 Residual stress distributions in nickel-based dissimilar metal pipe welds
SSM perspektiv Bakgrund Det är vanligt att nickelbasmaterial används som tillsatsmaterial vid svetsning av så kallade blandskarvar, det vill säga svetsning av olika metaller exempelvis austenitiskt rostfritt stål, ferritiskt stål eller nickelbaserade legeringar. Svetsfogen i sådana blandskarvar tillverkas vanligtvis genom att först svetsa ett nickelbasmaterial...

2024:10 Computational analysis of high-burnup fuel rod behaviour in PWR large-break LOCA
SSM perspective Background Quantum Technologies AB (QT) has for many years developed computational models for the thermomechanical behaviour of nuclear fuel in events such as LOCA and RIA. The research projects have been based on evaluations of tests on nuclear fuel in Halden Reactor Project (HRP) and Studsvik Cladding Integrity Project (SCIP). The models developed by QT enable analyses and...

2024:06 In search of lost storms: or can one infer the magnitudes of extremely rare flood events from short observational records?
SSM perspektiv Bakgrund Kärnkraftverken, övriga kärntekniska anläggningar och andra verksamheter som acceleratorerna ESS och MAX IV ska kunna motstå yttre händelser, såsom väderfenomen, i sådan omfattning att säkerhetssystemens förmåga att utföra sina uppgifter inte äventyras. Fukushima-olyckan i Japan 2011 är ett exempel...

2023:14 Effect of gamma-irradiation on the redox states of the structural iron in bentonite clay
SSM perspective Background Bentonite clay is used as buffer and backfill material which form engineered barrier in the spent fuel repository. The buffer material surrounding the copper canister will be exposed to gamma and neutron radiations, especially during the first few hundred years after closure of the repository. The redox states of the structural iron in montmorillonite, the dominant...

2023:13 TPR 2023 Fire Protection Swedish National Assessment Report
Executive Summary The European Union’s Nuclear Safety Directive 2014/87/EURATOM (NSD) requires the member states to undertake topical peer reviews (TPR) every 6 years. The first topical peer review concerned Ageing management and started in 2017. The member states, acting through the European Nuclear Safety Regulators Group (ENSREG), decided that the topic for the second topical peer review...

2023:11 Study of degradation of spent fuel’s structural material and core components under long-term wet storage
SSM perspective Background Sweden is managing the spent nuclear fuel and core components from its commercial nuclear reactors with a national strategic plan. The fuel and core components are initially stored at the reactor site. After an on-site storage period to comply with transportation limits on decay heat and radiation, these materials are shipped to the Clab (Central Interim Storage...
