Analysis on the Heat Transfer of Outlet Nozzle and Steam Cavity for SCWR RPV Using CFD
This paper focuses on the application of Fluent to the numerical simulating of a Super-Critical WaterReactor (SCWR) outlet nozzle and steam cavity structural design. Computational Fluid Dynamics(CFD) can be used to investigate the stable behavior around super-critical conditions along the flowchannel in outlet nozzle and steam cavity. Based on RPV conceptual configuration design, with shellmade by 508-III low alloy forging and outlet nozzle and steam cavity made by Inconel 690 forging, anumerical simulation is used to study the temperature distribution on the outlet nozzle and steam cavity,which is important to determine that whether the materials and structure of outlet nozzle and steamcavity is feasible for SCWR reactor pressure vessel (RPV). The simulation results indicate that themaximum temperature reaches 547K at welding line between 508-III shell and Inconel 690 nozzle, andit will assist in validating the direction of configuration optimization and material selection for thedesign activities.
