Abstract

Abstract

Bottom nozzle is an important component of CF3 fuel assembly, with the important functions of filtering foreign matters, circulating coolant and supporting the fuel assembly. In this paper, single-phase computational fluid dynamics (CFD) technology and hydraulic test methods are respectively used to study the hydraulic properties of CF3 fuel assembly in view of the flow function of the bottom nozzle. The calculation and test results show that the resistance coefficient of the bottom nozzle of CF3 fuel assembly is 5% different from that of AFA3G, which meets the requirements of hydraulic design of CF3 fuel assembly in terms of coolant fluidity.
