摘要：

The reactor coolant pump (RCP) is the machinery used in nuclear power facilities to move coolant. So RCP operation must be safe in order for nuclear power plants to operate reliably. It was discovered throughout the experiment that the flow rate of RCP was unsteady between 0.875 Q0 and 0.85 Q0 and the pressure pulsation increased dramatically. As the flow drops, the head no longer increases, but instead declines. The condition of pump is in the hump region. This research conducts tests to determine the characteris-tics of pressure pulsation and uses numerical simulation to investigate the causes of increased pressure pulsation. According to the study, when the pump was working in hump region, the amplitude of low -frequency signal increases as a result of this(C) 2022 Elsevier Ltd. All rights reserved.
