Seismic analysis of metering pumps in nuclear power plants

On the process pipeline of a nuclear power plant, the metering pump plays a role in regulating the flow rate. During the operation of the power plant, the accuracy and stability of the metering pump are important components of the safe operation of the system. For some critical systems, it is still required to ensure that the production line will not be damaged in the event of an earthquake and that it can operate stably during or after the earthquake. In this paper, ANSYS software is used to simulate the three-dimensional numerical simulation of the metering pump and conduct seismic analysis, which is of great significance for the integrity of the metering pump under the action of earthquake and the safe operation of the production line.
