• 2022:10 Internal dosimetry of radionuclides that can be released during an accident at the European Spallation Source (ESS)

  Läs mer SSM perspective Background To strengthen the material science research in Europe, the European Spallation Source (ESS) is being built in Lund in the southern part of Sweden. In the spallation process, neutrons are generated when the accelerated protons hit the tungsten target. In addition, a broad range of radioactive by-products is produced that differs from the fission products...

• 2022:09 Assessment of modelling approaches for axial gas flow inside LWR fuel rods

  SSM perspective Background The fuel rod analysis program SCANAIR has been developed by IRSN (Institut de Radioprotection et de Sûreté Nucléaire) for analysis of reactivity initiated accidents (RIA) in light water reactors. The Swedish Radiation Safety Authority (SSM) has access to SCANAIR in exchange for annual contributions for its further development. The development...

• 2022:08 Geophysical surveys on sub marine land- and rock slides and on alpine glaciers

  SSM perspective Background The future climate evolution and the impact it might have on a repository for radioactive waste is important when assessing the long-term safety. In a project funded by SSM (Holmlund et al. 2016), bathymetric data from the Southern Quark area between Sweden and Åland, provided by the Swedish Maritime Administration, were analysed, as well as terrestrial data from...

• 2022:04 Warm Pre-Stressing mechanisms

  SSM perspective Background Swedish nuclear power plants (NPP) were originally designed and analyzed with an assumed operating period of approximately 40 years. As Swedish NPPs reach their original technical design life the safety of the additional operating time has to be verified. With increased operating time, the shift in the fracture toughness curve of the reactor pressure vessel (RPV)...

• 2022:03 Effect of Neutron Irradiation on the Oxidation and Corrosion of Austenitic Stainless Steels

  SSM perspective Background Reactor pressure vessel internal components of austenitic stainless steel located close to the core are subject to a high neutron flux. Irradiation by fast neutrons induces changes in the material that affect microstructure, mechanical properties and microchemistry. These changes eventually lead to an increased susceptibility to irradiation assisted stress corrosion...

• 2021:28 Analysis of Radon Levels in Swedish Dwellings and Workplaces

  SSM perspektiv Bakgrund Exponering för radon anses vara den viktigaste orsaken till lungcancer näst efter rökning och beräknas orsaka omkring 500 lungcancerfall årligen i Sverige. Därför är det viktigt att sänka radonhalten i inomhusluften, speciellt om nivån överstiger referensnivån 200 Bq/m³. För att kunna uppdatera beräkningar...

• 2021:21 Region-specific radioecological evaluation of accidental releases of radionuclides from ESS

  SSM perspective Background To strengthen the material science research in Europe, the European Spallation Source (ESS) is being built in Lund in the southern part of Sweden. In the spallation process, neutrons are generated when the accelerated protons hit the tungsten target. In addition, a broad range of radioactive by-products are produced that differs from the fission products produced...

• 2021:20 Effects of additives on UO2 fuel behavior: expanded edition

  SSM perspective Background The Swedish Radiation Safety Authority (SSM) follows the development of nuclear fuel closely. Fuel with additives like chromia and gadolinia is used in Swedish reactors and fuel with even better thermal and mechanical properties is under development. This project is an in-depth study of data and models regarding the impact of additives on the properties of uranium...
