  1. 1. Utvecklingsbehov av probabilistisk säkerhetsanalys (PSA) för applicering på SMR:er

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad kärnfysik

    Författare :Udd Emilia; [2024]
    Nyckelord :PSA; SMR; probabilistisk säkerhetsanalys; säkerhetsanalys; kärnkraftssäkerhet; BWRX-300;

    Sammanfattning : Nuclear power is an important part of Sweden's energy system and contributes with about 30 % of the supplied electric energy. Interest in new construction is currently high and one type of reactor that may be built is small modular reactors, SMRs. LÄS MER

  3. 2. Risk Implications of Small Modular Nuclear Reactor Implementations: the Case of the Nordics

    Master-uppsats, Uppsala universitet/Institutionen för samhällsbyggnad och industriell teknik

    Författare :Denis Mijolović; [2023]
    Nyckelord :Small Modular Nuclear Reactors; Nuclear Energy; Energy Policy; Energy Transition; Risk Management; Scandinavian Energy Strategy;

    Sammanfattning : Climate change is no novelty – we witness its disastrous impact more and more by each day. Although we already started envisaging a future where the vitality of our societies is derived not from conventional fossil fuels, but from a sophisticated, clean, and steadfast energy source – the latest benchmarks tracked by leading global energy agencies show grim performance, thereby calling for an intervention.

  4. 3. 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

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

    Master-uppsats, KTH/Fysik

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

    Sammanfattning : 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. LÄS MER

  7. 5. 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
