  1. 1. 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.

  3. 2. Ekologisk kompensation: en utvärdering av åtgärder för gölgroda (Pelophylax lessonae) i Forsmark

    Kandidat-uppsats, SLU/Dept. of Ecology

    Författare :Malin Karlsson; [2018]
    Nyckelord :ekologisk kompensation; gölgroda; Pelophylax lessonae; Rana lessonae; metapopulation; damm;

    Sammanfattning : Exploatering av värdefulla naturområden kan kompenseras genom s.k. ekologisk kompensation. Ekologisk kompensation har hittills sällan tillämpats och därför saknas ofta uppföljning av dessa. LÄS MER

  4. 3. Investigation of Spent Nuclear Fuel Pool Coolability

    Master-uppsats, KTH/Reaktorteknologi

    Författare :Fredrik Nimander; [2011]
    Nyckelord :;

    Sammanfattning : The natural catastrophe at Fukushima Dai-ichi 2011 enlightened the nuclear community. This master thesis reveals the non-negligible risks regarding the short term storage of spent nuclear fuel. The thesis has also investigated the possibility of using natural circulation of air in a passive safety system to cool the spent nuclear fuel pools. LÄS MER

  5. 4. Upgrade and validation of PHX2MCNP for criticality analysis calculations for spent fuel storage pools

    Uppsats för yrkesexamina på avancerad nivå, Tillämpad kärnfysik

    Författare :Cecilia Larsson; [2010]
    Nyckelord :criticality; safety analysis; validation;

    Sammanfattning : A few years ago Westinghouse started the development of a new method for criticality calculations for spent nuclear fuel storage pools called “PHOENIX-to–MCNP” (PHX2MCNP). PHX2MCNP transfers burn-up data from the code PHOENIX to use in MCNP in order to calculate the criticality. LÄS MER
