The frequencies and amplitudes of the pressure pulsation caused by the model pump of the reactor coolant pump are obtained through the hydraulic test using the model pump of a reactor coolant pump. The relationship between the amplitude of the pressure pulsation and the head fluctuation of the model pump head is also obtained. The pressure pulsation amplitude of the rotational speed frequency is the biggest one, and the amplitudes of the blade passing frequencies (BPF) are smaller than that of the rotational speed. The amplitudes of the pressure pulsation above 6 BPF are gradually reduced to zero amplitude. The pump head fluctuation based on the dynamic pressure measurement is 0.72% of the rated head, and 0.63% based on the static pressure measurement. It is a meaningful result that the pump head fluctuation based on the dynamic pressure is almost the same the pump head fluctuation based on the static pressure. From this result, the amplitude of the pressure pulsation can be enveloped conservatively using the pump head fluctuation that can be measured easily from the static pressure at steady state condition.
