  1. 6. A VVER1000 primary side model in Apros

    Master-uppsats, KTH/Fysik

    Författare :Karl-Edvin Strand; [2023]
    Nyckelord :Apros; VVER1000; PWR; Modelling; HPIS; Boron acid; Apros; VVER1000; PWR; Modellering; HPIS; Borsyra;

    Sammanfattning : Nuclear power plants generate electricity by means of splitting atoms. The basic safety requirements and objectives are to protect the people, society, and the environment from radiological accidents, limit harmful effects of ionizing radiation during operation and take all reasonable practical steps to prevent radiological accidents.

    Sammanfattning : Transient analyses at Forsmark nuclear power plant are currently performed using realistic computer models in conjunction with conservative estimates of initial- and boundary conditions. This is known as the combined methodology. LÄS MER

  5. 9. Feasibility of HALEU-loaded Breed-and-Burn Molten Salt Fast Reactor without Online Actinide Treatment

    Master-uppsats, KTH/Fysik

    Författare :Lei Shi; [2023]
    Nyckelord :Molten salt; Chloride fuel; Fast reactor; Breed-and-Burn; Smält salt; kloridbränsle; snabbreaktor; avel och bränning;

    Sammanfattning : Molten Salt Fast Reactors (MSFRs) have prominent advantages such as fuel breeding, nuclear waste transmutation, and inherent safety. They are the only liquid-fueled nuclear reactors currently receiving significant attention as fourth-generation advanced nuclear systems. LÄS MER

  7. 10. Predicting Reactor Instability Using Neural Networks

    Kandidat-uppsats, KTH/Fysik

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

    Sammanfattning : 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. LÄS MER
