The flow characteristics of reactor fuel assembly always intrigue the designers and the experimentalistsamong the myriad phenomena that occur simultaneously in a nuclear core. In this work, the visualexperimental method has been developed on the basis of refraction index matching (RIM) and particleimage velocimetry (PIV) techniques to investigate the detailed flow characteristics in China fast reactorfuel subassembly. A 7-rod bundle of simulated fuel subassembly was fabricated for fine examination offlow characteristics in different subchannels. The experiments were performed at condition of Re ¼ 6500(axial bulk velocity 1.6 m/s) and the fluid medium was maintained at 30 C and 1.0 bar during operation. As for results, axial and lateral flow features were observed. It is shown that the spiral wire has aninhibitory effect on axial flow and significant intensity of lateral flow mixing effect is induced by the wire. The root mean square (RMS) of lateral velocity fluctuation was acquired after data processing, whichindicates the strong turbulence characteristics in different flow subchannels.
