  3. 2. Impact of Peroxide Speciation on the Kinetics of Oxidative Dissolution of UO2

    University essay from KTH/Kemi

    Author : Hazal Aydogan; [2022]
    Keywords : Spent nuclear fuel; H2O2; HCO3-; Speciation; Kinetics; Använt kärnbränsle; H2O2; HCO3-; Speciering; Kinetik;

    Abstract : Slutförvaring av använt kärnbränsle måste vara säker under 100 000 år eller mer för att förhindra att miljön skadas och att människor påverkas av långlivade radionuklider. Även om anläggningar för geologiskt djupförvar är utformade för att vara hållbara i många år, kan använt kärnbränsle komma i kontakt med grundvattnet i händelse av att flera barriärer brister.

  4. 3. Qualification of a Physical Model of Cladding Creep During Dry Storage of Spent Nuclear Fuel

    University essay from KTH/Fysik

    Author : Robin Andersson; [2022]
    Keywords : Dry Storage; Thermal Creep; Zircaloy-4; Pellet-Cladding Interaction; Torrt Förvar; Termisk Krypning; Zircaloy-4; Kuts-Kapsling Interaktion;

    Abstract : In dry interim storage of spent nuclear fuel, thermal creep is one of the major threats to the fuel cladding integrity due to the constant decay heat generation from the fission products and minor actinides in the fuel, and the increase in fuel rod internal pressure which is present after burnup. Plenty of research has been done on either empty cladding tubes irradiated in a research reactor, or on spent fuel that is defueled prior to the examination. READ MORE

  5. 4. Geological characterisation of geophysical lineaments as part of the expanded site descriptive model around the planned repository site for high-level nuclear waste, Forsmark, Sweden

    University essay from Lunds universitet/Geologiska institutionen

    Author : Aron Bakker; [2021]
    Keywords : Forsmark; deformation zones; Svecokarelian; Sveconorwegian; ductile-brittle transition; brittle deformation; mylonite; Earth and Environmental Sciences;

    Abstract : The Swedish Nuclear Fuel and Waste Management Co. (SKB) started a project in 2020 near Forsmark, Sweden with the aim to expand the deformation zone model to encompass the entire catchment area around the planned repository for spent nuclear fuel. READ MORE

  6. 5. Compilation and evaluation of validations of computer codes for spent nuclear fuel – a review

    University essay from Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

    Author : Staffan Fors; [2019]
    Keywords : Nuclear fuel; Kärnbränsle; Slutförvar; Fissionsprodukter; Physics and Astronomy;

    Abstract : This report describes a systematic review regarding validations of calculations by measurements of isotopic compositions, or decay heat, on spent nuclear fuel, SNF. 15 relevant or otherwise interesting studies, were found. Two reports were chosen among the found studies and analyzed. READ MORE
