  1. 1. Non-proliferation and safeguards aspects of SMR’s in Sweden : A study on the future electricity demand in Sweden and the implications on nuclear safeguards from the deployment of SMRs in Sweden

    University essay from Uppsala universitet/Tillämpad kärnfysik

    Author : Waldemar Andersson; [2023]
    Keywords : SMR; Small modular reactor; Safeguards; Non-proliferation;

    Abstract : This project aims to investigate and analyze crucial aspects related to the deployment of Small Modular Reactors (SMRs) in Sweden. SMRs have risen as a competitor to large-scale nuclear power plants with cost-competitiveness and cogeneration purposes in focus. READ MORE

  3. 2. Development of a computational method for determining gamma energy escape from calorimeters at CLAB

    University essay from Uppsala universitet/Tillämpad kärnfysik

    Author : Amela Mehic; [2022]
    Keywords : Nuclear physics; Calorimeter; SNF; MCNP; Dose rate; CLAB; Gamma energy; Fuel assembly; Form function; Attenuation coefficient; Gamma spectroscopy;

    Abstract : Swedish Nuclear Fuel and Waste Management Company- SKB has conducted measurement campaigns at the Swedish central interim storage facility for spent nuclear fuel- CLAB over the years, extending from year 2003 to 2019 where the gamma energy escape was acquired. At CLAB the spent nuclear fuel assembly is inserted into the calorimeter; device intended to measure temperature increase due to decay heat from the fuel assembly. READ MORE

  4. 3. Spent Nuclear Fuel under Repository Conditions : Update and Expansion of Database and Development of Machine Learning Models

    University essay from KTH/Kemi

    Author : Maria Abada; [2022]
    Keywords : Spent nuclear fuel; spent nuclear fuel dissolution; spent nuclear fuel corrosion; machine learning model; dissolution predictions; Utbränt kärnbränsle; upplösning av utbränt kärnbränsle; korrosion av utbränt kärnbränsle; maskininlärningsmodeller; prediktioner av upplösning;

    Abstract : Förbrukat kärnbränsle är mycket radioaktivt och behöver därför lagras i djupa geologiska förvar i tusentals år innan det säkert kan återföras till naturen. På grund av de långa lagringsperioderna görs säkerhetsanalyser av de djupa geologiska förvaren. READ MORE

  5. 4. 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.

  6. 5. 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
