• 2024:01 Stress field modelling of the Forsmark lens – Correlation of stress measurements with stress field simulations

  SSM perspektiv Bakgrund och syfte Kunskap om det nuvarande bergspänningsfältet i Forsmark ligger till grund för att karakterisera bergmassans rådande mekaniska och hydrauliska beteende. Endast med en god förståelse för den geomekaniska miljön är en analys av bergmassan framtida hydro-mekaniska beteende möjlig. Baserat på befintliga bergspänningsmätningar...

• 2023:15 Numerisk analys av restspänningar i bandpåsvetsad plätering i svenska reaktortryckkärl

  Strålsäkerhetsmyndighetens perspektiv Bakgrund Reaktortryckkärl tillverkas vanligtvis av låglegerade ferritiska stål som på insidan beläggs med ett eller flera lager av rostfritt stål, så kallad plätering eller på engelska cladding. Den rostfria pläteringen påverkar den strukturella integriteten på flera sätt, dels har...

• 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...

• 2023:12 Investigation of the limits of detection for specific radionuclides in soil from the European Spallation Source (ESS) using radiometric and mass spectrometric methods

  SSM perspective Background In Lund, the construction of the European Spallation Source (ESS) research facility is underway and the facility is also undergoing a stepwise licensing procedure in accordance with relevant legal requirements. At ESS, neutrons will be produced by spallation when high-energy protons from a linear accelerator hit a rotating tungsten beam target. The neutrons released...

• 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...
