Main coolant pump (MCP) of SMART Pilot is a canned-motor-type axial pump to circulate the primary coolant between nuclear fuel and steam generator in the primary system. The reactor is designed to operate under condition of 310℃ and 14.7 ㎫. Thus the MCP has to be tested under same operating condition as reactor design condition to verify its performance and safety. In this work, the performance test of a prototype MCP was carried out under the same operating condition and hydro dynamic performance curves were obtained as a result. At the same time, installation effect of an M-Pitot type flowmeter was also investigated by CFD and experiment. Two flowmeters were installed at different locations and the measured values were compared to each other. The averaged deviation of the flowrate at the design point is about 5%.
