摘要：Based on design criteria of fuel handling equipment and storage installation in land-based nuclear power plants and ship conditions for nuclear-powered vessels, a state classification is developed for the SFP(spent fuel pool) in marine nuclear power platform, including normal condition, accident condition, heel & trim operation condition and relevant acceptance criteria. A calculation model, accuracy verified by steady state calculation before developing limiting accidental analysis, is established to analyse the thermal safety of the SFP, including geometry structure and heat transfer models. Simulation of loss of cooling system and water inventory scenario shows that reject water into the SFP within the first 14 hours after the accident is good enough to bring spent fuels into a safer state. Meanwhile, parameters sensitivity study show that the timing of refilling and coolant flow rate is much more important than the coolant temperature.
