  1. 1. Computational Fluid Dynamics and Modeling of a Free Surface Flow

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Mathieu Marmier; [2023]
    Keywords : CFD; Free Surface Flow; VOF; STAR-CCM ; Multiphase Simulation; Nuclear Engineering; Fluid Mechanics;

    Abstract : This project deals with the CFD modelling of a free surface flow. The aim is to develop and validate a fast and accurate numerical model for stratified two-phase flows. Volume of Fluid (VOF) multiphase model is employed. The purpose is to use the developed numerical model for the design of an element within a compact nuclear reactor. READ MORE

  3. 2. Machine Learning model applied to Reactor Dynamics

    University essay from KTH/Fysik

    Author : Dionysios Dimitrios Nikitopoulos; [2023]
    Keywords : Master Thesis; Machine Learning; stability; Energy distribution profiles; Prediction; frequency; decay ratio; Data processing; POLCA-T; Pytorch; testing data; RMSE. ii;

    Abstract : This project’s idea revolved around utilizing the most recent techniques in MachineLearning, Neural Networks, and Data processing to construct a model to be used asa tool to determine stability during core design work. This goal will be achieved bycollecting distribution profiles describing the core state from different steady statesin five burn-up cycles in a reactor to serve as the dataset for training the model.

  4. 3. Commissioning of ITER heat rejection system for low load

    University essay from Uppsala universitet/Tillämpad kärnfysik

    Author : Elizaveta Yakovleva; [2023]
    Keywords : commissioning; ITER; fusion; control logic; cooling system; I C;

    Abstract : This project has commissioned the control logic of the Heat Rejection System (HRS) at ITER, the international fusion project. The HRS is a large system, including 10 cooling towers, 13 pumps, and pipes large enough for a water flow of several thousand kg/s. All of this will becontrolled with automatic control logic.

  5. 4. Exhaust system for hydrogen fuelled combustion engines: effect of high-water content on the SCR vanadium catalyst

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Cecilia Zambelli; [2023]
    Keywords : ;

    Abstract : Transportation represents a key secot in the journey towards a greener future, and alternative solutions are needed to meet the decarbonaisation need. Hydrogen internal combustion engines could represent a solution in the short-term, allowing for emission reduction with limited modification to the already existing traditional combustion engines.

  6. 5. Improved Modelling For Oxidation Of Zircalloy Fuel Cladding Tubes In PWRs

    University essay from KTH/Fysik

    Author : Rafaël Bellachia; [2023]
    Keywords : Nuclear Engineering; Corrosion; Zircalloy; PWR; Nuclear Fuel; Kärnteknik; Korrosion; Zircalloy; PWR; Kärnbränsle;

    Abstract : The fuel cladding is an essential component in the defence-in-depth strategy for nuclear safety. Its integrity and durability are therefore critical for maintaining acceptable safety conditions. However, the integrity of the cladding can be compromised during normal operation due to corrosion and hydriding. READ MORE
