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

  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 ... protons hit the tungsten target. In addition, a broad range of radioactive by-products are produced that differs from the fission products produced in a nuclear reactor. In case of an accident scenario target...

• 2021:10 Establishment and use of attention values in environmental fatigue assessments

  reach their original technical design life, re-assessment of the fatigue life of structural components is needed for safe long term operation (LTO). In these re-assessments one must consider that new knowledge ... life must be considered. One common method to verify the fatigue life of structural components subjected to an LWR coolant environment is to use so-called attention values. This simplistic method is beneficial...
