16. Utökad användning av termografering för en förstärkt driftklarhetsverifiering
M1-uppsats, KTH/Hållbar produktionsutveckling (ML)Sammanfattning : Vattenfall AB är ett europeiskt energiföretag som strävar efter att bli fossilfria och investerar i att öka andelen energiproduktion med låg koldioxidutsläpp. Företaget äger kärnkraftverk i Ringhals där de producerar stora mängder fossilfri el.

17. Applications of steel-plate composite structures for nuclear modular construction
Master-uppsats, KTH/BetongbyggnadSammanfattning : Despite being the world’s second most important low-carbon source of electricity, the development of nuclear capacities is limited and does not comply with the International Energy Agency’s Sustainable Development Scenario. One of the main reasons for this lack of development is high and increasing costs of new nuclear capacities. LÄS MER

19. Validating results from the Molten Salt Reactor Experiment by use of turbulent CFD simulations : A study of a modified U-tube shell-and-tube primary heat exchanger and radiator with molten salts
Master-uppsats, Luleå tekniska universitet/RymdteknikSammanfattning : Background Nuclear reactors utilizing molten fuels rather than solid fuels show a massive advantage in energy yield, waste handling and safety features. The only successful reactor utilizing a molten fuel was called the ‘Molten Salt Reactor Experiment’ (MSRE), built and operated in the Oak Ridge national laboratory (ORNL) in Tennessee, U.S.A. LÄS MER
20. A Numerical Study of Melt Pool Heat Transfer in the IVR of a PWR
Master-uppsats, KTH/FysikSammanfattning : This thesis aims to provide the thermal condition of melt pool convection by CFD simulation, which is important to the assessment of the invessel melt retention (IVR) strategy widely adopted in Generation III pressurized water reactors (PWRs). As a severe accident mitigation measure, the IVR strategy is realized through external cooling of the lower head of a reactor pressure vessel (RPV). LÄS MER
