Description

Based on analysis on direct-contact condensation of high-pressure saturation steam in sub-cooled liquid within core makeup tank (CMT) for passive high-pressure injection system of AC600, liquid conductivity multiplication factor and uniform temperature mixing layer are introduced to reflect the strong effect on condensation, which are caused by vapor injecting into upper liquid layer. The simplified physical and mathematical modes are proposed for condensation heat transfer in cylinder wall and liquid region of CMT separately. A numerical simulation program is developed to calculate the steam condensation rates in CMT, and the simulation results are in good agreement with the data obtained through experiment
