This paper described the test of flow balance in fuel assemblies of the pressurized water reactor power plant (300MW) which is the first plant designed and to be built by our country. The resistance matching between parts of the four different structure of fuel assemblies was reasonably settled. The difference of the coolant between them was adjusted to less than 1%. The design of the plug was improved after the test. The dimension of orifice for upper grid plate of the reactor core and resistance coefficients of the outlet for various assemblies have been determined. The test results provide the reliable experimental basis for the thermal-hydraulic and structure design of the Qinshan nuclear power plant.
