  1. 21. Use of the JET pedestal database to assess the role of ion temperature and plasma rotation on the discrepancy between ideal peeling-ballooning model and experimental data

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Max Eichenberger; [2022]
    Keywords : Nuclear fusion; Joint European Torus JET ; H-mode; pedestal; Edge-localized-modes ELMs ; Peeling-Ballooning; relative shift; ion temperature; plasma rotation; Kärnfusion; JET Joint European Torus ; H-läge; piedestal; ELM Edge Localized­Modes ; peeling-ballooning; relativ förskjutning; jontemperatur; plasmarotation;

    Abstract : Next-generation and present fusion devices such as the Joint European Torus (JET) aim for plasma operations in H-mode, a plasma regime with high confinement and low loss of energy and fuel that results from a barrier for heat and particle transport at the plasma edge, the pedestal. Due to steep gradients of the density, temperature and pressure profiles, the pedestal experiences instabilities called Edge-localized-modes (ELMs) which lead to large fluxes of heat and particles that might damage machine components.

  4. 23. 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.

    Keywords : ;

    Abstract : In this thesis, an analysis is made of wind energy and specificallywind energy and how it is utilized both in Greece, in European Union andworldwide. Initially, the forms of wind energy sources, advantages anddisadvantages, and what exists in Greece and worldwide will be studied. READ MORE

  6. 25. 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
