  1. 1. Reactor Chemistry in LWR SMRs : Determination of the rate constant for the reaction between boric acid and hydroxyl radicals

    Master-uppsats, KTH/Tillämpad fysikalisk kemi

    Författare :Fredrik Petersson; [2023]
    Nyckelord :LWR; SMR; Water chemistry; Radiolysis; Boric acid; LWR; SMR; vattenkemi; Radiolys; Borsyra; Hydroxylradikal;

    Sammanfattning : Ett problem vid byggandet av nya kärnkraftverk för elproduktion är de stora investeringskostnaderna samt den långa tiden det att få tillstånd för en reaktor och bygga den. Nyligen färdigställdes den tredje reaktorn vid Olkiluoto I Finland, den tog 18 år att färdigställa exklusive tiden att få tillstånd för reaktorn. LÄS MER

  3. 2. Design of cooling-air permeable coil support

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Rozbeh Ghassemi; [2023]
    Nyckelord :Topology optimization; FEM-simulations; CFD-simulations; Material selection; Topologioptimering; FEM-simuleringar; CFD-simuleringar; Materialval;

    Sammanfattning : Coil supports are integral load-bearing components employed in generators andmotors. They serve the purpose of preventing excessive deformation and maintaininga stable position of the coils responsible for generating power and magnetic fieldswhen rotating. LÄS MER

  4. 3. Development and evaluation of solar heating solutions for Villages in the highlands of Peru

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Tom Rupert Göransson; [2023]
    Nyckelord :;

    Sammanfattning : In the Peruvian highlands, hundreds of thousands of people live in dwellings that are completely unheated. In this climate, nighttime indoor temperatures during the winter could be as low as 0°C. Indoor cold can cause thousands of respiratory diseases and increase winter mortality. LÄS MER

  5. 4. Dimensioning study of EPR2 fuel pool cooling system

    Master-uppsats, KTH/Fysik

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

    Sammanfattning : 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.

  7. 5. Feasibility study of evaporative cooling and toilet flushing using rainwater in a public building

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Claudia Reig Moril; [2023]
    Nyckelord :Rainwater; Evaporative cooling; Toilet flushing; Energy; Water; Feasibility.; Regnvatten; Evaporativ kyla; Toalettspolning; Energi; Vatten; Genomförbarhet.;

    Sammanfattning : The project "Feasibility of evaporative cooling and toilet flushing using rainwater in a public building" combines rainwater harvesting with the evaporative cooling technology and toilet flushing and explores the practicality and viability of implementing this innovative system in the city of Gothenburg, Sweden. This study comprehensively investigates various aspects related to water and energy, and the entire system is computationally modelled using the Equation Engineering Solver (EES) software. LÄS MER
