  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. Can Streams of Weapons Create Waves of Violence Between Farmers and Herders? : A qualitative case study on the role of Small Arms and Light Weapons in conflicts between farmers and herders

    Kandidat-uppsats, Uppsala universitet/Institutionen för freds- och konfliktforskning

    Författare :Emelie Aréen; [2023]
    Nyckelord :;

    Sammanfattning :  This paper empirically examines the relationship between the circulation of Small Arms and Light Weapons (SALW), and its effect on farmer-herder conflicts, particularly the risk of escalation. Researchers have emphasised the role of these weapons that are being frequently used in communal conflicts across several African countries. LÄS MER

  4. 3. Reliability Assessment of Passive ICS in an SMR as part of the PSA Analysis

    Master-uppsats, KTH/Fysik

    Författare :Graeme Trundle; [2023]
    Nyckelord :Passive system reliability; Probabilistic safety assessment; Reliability Methods of Passive Systems; Natural circulation; TRACE; RiskSpectrum; Passiv systemtillförlitlighet; Probabilistisk säkerhetsbedömning; Reliability Methods of Passive Systems; Naturlig cirkulation; TRACE; RiskSpectrum;

    Sammanfattning : Passive safety systems are increasingly being utilized in prospective nuclear power plant designs. Indeed, the use of safety systems driven by natural phenomena might be seen as an unmitigated virtue. LÄS MER

    Sammanfattning : The demand for fossil-free energy production is rising due to electrification and increased consumption in the energy system. There are also multiple climate goals to reach, to preserve the possibilities of a sustainable future. LÄS MER

  7. 5. Test rig for gear transmissions in electrical applications

    Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Gustaf Axelström; [2023]
    Nyckelord :power circulation; gear test rig; gear testing; effektcirkulation; testrigg; kugghjulstest;

    Sammanfattning : Due to the environmental problems associated with fossil fuels and a big need from the market, the majority of the automotive industry is going towards fully electric vehicles (EVs). To further reduce the environmental footprint there is ongoing research on the use of fossil-free lubricants, if they could be used to lubricate the drive train which could further reduce the use of fossil oil in the automotive industry.
