Effect of the Number of Freeze Valve Channels on Core Discharge Rate and Pressure in Core and Drain Tank

Analysis of the Influence of the Number of Freeze Valve Channels on Core Discharge Rate and Pressure in Core and Drain Tank has been conducted. This research employed a 2D freeze valve design representation using the Moving Particle Semi-implicit Method. This method utilizes the behavior and movement of particles within a predefined geometry, influenced by various physical parameters within the system. The aim of this study is to observe velocity profiles and pressure profiles during the core discharge process with variations in freeze valve geometries V1, V2, and V3. The results indicate that the core discharge times for V1, V2, and V3 are 4.75 s, 6.40 s, and 6.15 s respectively. V3 exhibits a lower average system pressure compared to V1 and V3, suggesting that V3 is more effective in managing pressure during the core discharge process.
