  • 2011:11 Handling Interfaces and Time-varying Properties in Radionuclide Transport Models

    Quintessa’s QPAC code has been used to investigate the Qeq approach. The conclusions from this simulation study are the following. The basic approach to calculating Qeq values is sound, however, narrow channels could lead to the same release as larger fractures with the same pore velocity, so a channel enhancement factor of √10 should be considered. A spalling zone that increases the area of...

  • 2019:03 Evaluation of the hydrodynamic model in PARET/ANL

    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. This ensures a possibility for SSM to do...

  • 2019:13 Organisatoriska risker avseende strålsäkerhet i ekonomiskt pressade lägen

    SSM perspektiv Bakgrund Kärnkraftsbranschen befinner sig i en ekonomiskt pressad situation. Höjda säkerhetskrav, åldrade anläggningar som kräver mer underhåll och låga elpriser leder till att resursanvändningen måste maximeras. Stora projekt pågår hos tillståndshavarna i syfte att effektivisera organisationerna. Nedskärningar...
