Abstract

Abstract

Based on the design of AP1000 power plant, a fully scaled experimental mock-up was built to simulate the high-temperature and high-pressure steam spraying, steam condensation under depressurization condition through Automatic Depressurized System（ADS）. The experiment recorded the flow characteristics and 3D temperature and velocity distribution around sprayer in IRWST by dot matrix of thermocouples and Particle Image Velocimetry Particle Image Velocimetry（PIV）. By studying the thermal stratification and natural circulation in the IRWST under depressurization condition when undercooling water is large, an optimization scheme was proposed to improve the efficiency of cooling water in IRWST.
