  1. 1. Dimensioning study of EPR2 fuel pool cooling system

    University essay from KTH/Fysik

    Author : Thomas Rubler; [2023]
    Keywords : EPR2; PTR; spent fuel pool; heat exchange; EPR2; PTR; bassäng för utbränt kärnbränsle; värmeväxling.;

    Abstract : The PTR system allows the EPR2 fuel pool to be cooled. The evacuation of the residual power fromthe pool is ensured by several heat exchangers and pumps, which have to be dimensioned in order to meetdifferent requirements.In order to dimension them, the worst-case scenario of the components must first be determined.

  3. 2. Optimization of Heat Exhaust in the Edge of Tokamaks via Controlled Magnetic Stochastization

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

    Author : Amit Kharwandikar; [2020]
    Keywords : Resonant Magnetic Perturbations; Tokamak; Divertor; Steady-state heat deposition; Power exhaust; Perturbation optimization; Resonant magnetiska störningar; Tokamak; avledare; statisk värmeavledning; värmeavledningen; störningsoptimering;

    Abstract : The protection of plasma facing components from heat and particle overloads is paramount to ensure the operability and desired lifetime of magnetic fusion devices. The possibility of using external 3D magnetic perturbations to improve the steady-state heat exhaust in diverted tokamaks has been studied in this thesis. READ MORE

  4. 3. Modelling of Laser Welding of Aluminium using COMSOL Multiphysics

    University essay from KTH/Materialvetenskap

    Author : Jie Chen; [2020]
    Keywords : laser welding process; aluminium alloy; thermal-mechanical; COMSOL Multiphysics; hot cracking; thermal model; CFD model; mechanical model; Marangoni effect; lasersvetsningsprocess; aluminiumlegeringar; termisk-mekanisk; COMSOL-flerfysik; hetsprickning; termisk modell; CFD-modell; mekanisk modell; Marangoni-effekt;

    Abstract : This thesis presents a modelling approach of laser welding process of aluminium alloy from the thermo-mechanical point of view to evaluate the occurrence of hot cracking based on simulation results and relevant criteria. The model was created stepwise in COMSOL Multiphysics, starting with the thermal model where heat conduction of solid and liquid phase was computed. READ MORE
