  1. 1. Predicting Reactor Instability Using Neural Networks

    University essay from KTH/Fysik

    Author : Hilborn Hubert; [2022]
    Keywords : Boiling Water Reactors; Density Wave Instability; Multi-Layer Perceptron; Support Vector Regression; Kernel-Ridge Regression;

    Abstract : The study of the instabilities in boiling water reactors is of significant importance to the safety withwhich they can be operated, as they can cause damage to the reactor posing risks to both equipmentand personnel. The instabilities that concern this paper are progressive growths in the oscillatingpower of boiling-water reactors. READ MORE

  3. 2. Improving the understanding of heat transfer when boiling solid foods

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Dat Nguyen Trong; [2022]
    Keywords : fluid-to-particle heat transfer coefficient; heat transfer; pool boiling; boiling; simmering; starch gelatinization; unsteady-state heat transfer analysis; food engineering; Agriculture and Food Sciences;

    Abstract : Determination of the fluid-to-particle heat transfer coefficient hfp is a fundamental problem in food engineering. Solutions to this problem help food technologists and cooks prepare foods with desired characteristics more efficiently in time and energy use. This study aims to determine the hfp-value in simmering and boiling solid foods. READ MORE

  4. 3. Micro-architectured materials for thermal management : Porous graphite/graphene boiling enhancement structures

    University essay from Uppsala universitet/Tillämpad mekanik

    Author : Melody Ghaderidosst; [2022]
    Keywords : Microarchitecture; TPMS; Gyroid; thermo-mechanical; computational homogenization; graphite; graphene;

    Abstract : The convergence of the digital and physical world encourages advances in high-speed telecommunication and fifth generation technology. Two-phase heat transfer systems are common engineering solutions. However, due to the large frequency spectra in 5G, the systematic heat generation increases requiring more efficient thermal management. READ MORE

  5. 4. Feasibility study on Thermal Anemometry at LWR conditions

    University essay from KTH/Fysik

    Author : Abishek Baskar; [2021]
    Keywords : Nuclear Enginnering; Thermal-Hydraulics; Instrumentation; Material technology; Fluid Dynamics. Light water reactors;

    Abstract : Dryout and Departure from Nucleate boiling (DNB) are utmost thermal-hydraulic concerns for the safety of LWRs. The behavior of two-phase flows at these conditions is still not fully understood. There is at least a need for a good local velocity and void fraction database at these conditions. READ MORE

  6. 5. Development of a Nordic BWR plant model in APROS and design of a power controller using the control rods

    University essay from KTH/Fysik

    Author : Jonathan Al-Ani; [2021]
    Keywords : APROS; Dynamic process simulation; System code; Nuclear reactor; nuclear power; BWR; Boiling Water Reactor; closed cycle; steam cycle; one-dimensional flow; Westinghouse; control rods; APROS; Dynamisk processimulering; Beräkningsmodell; Kärnkraft; BWR; Kokvattenreaktor; ångcykel; en-dimensionell flödesmodell; Westinghouse; kontrollstavar;

    Abstract : In this master thesis an input-model of a Nordic BWR power plant has been developed in APROS. The plant model contains key systems and major thermohydraulic components of the steam cycle, including I&C systems (i.e. power, pressure, level and flow controls). READ MORE
