• 2020:13 Core data Research at Uppsala University

  SSM perspective Background This project is to support a research group at Uppsala University in the research field of nuclear data for applications. Nuclear data research is about measuring microscopic ... different nuclear reactions and developed theoretical nuclear data models. The experiments were focused on fission reactions. The experiments were performed in different facilities in Europe such as the IGISOL-facility...

• 2020:08 Identifying radiologically important ESS-specific radionuclides and relevant detection methods

  SSM perspective Background The European Spallation Source (ESS) facility is under construction in Lund, Sweden. High-energy protons will be accelerated in a linear accelerator and generate neutrons when ... monitoring program when the ESS facility starts to generate neutrons in a few years. Results Based on an extensive literature review of ESS-relevant radionuclides the authors concluded that radionuclide...

• 2020:12 Assessment of the QT-COOL coolant channel module against the PBF RIA 1-2 experiment

  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 ... Swedish Radiation Safety Authority (SSM) has access to SCANAIR in exchange for annual contributions for its further development. This ensures a possibility for SSM to do own analysis of fuel rods in reactivity...

• 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...

• 2020:16 Estimates ofJ-integral and COD for circumferential through wall cracks under global bending including the effect of pipe end restraint

  SSM perspective Background Leak-before-break (LBB) piping assessments have shown that piping systems can withstand long through-wall cracks before pipe rupture is expected. This is somewhat because pipe ... investigate what impacts the assumption degree of restraint at the ends of an analysed piping segment have on leak-before-break assessments and leakage rate calculations. Results The study conclude that crack...

• 2020:02 Models for axial gas flow and mixing in LWR fuel rods

  SSM perspective Background Fission gases inside a fuel rod plays an important role in the behaviour of the fuel, both during normal operation and during events and accidents. Fission gases are released ... experiments have been done. Relevance With this project, SSM has obtained a computer code that can model axial fission gas transport in a fuel rod. SSM has also gained insight into how such a model is implemented...
