A million kilowatt nuclear power plant is designed with three water ring vacuum pumps to establish and main-tain vacuum in the condenser.Under normal operating conditions,two pumps are put into service and the other one acts as the backup.The vacuum pumps and the condenser are both cooled by seawater.This paper analyzes the limit vacuum de-gree value in the condenser during summer through calculation and the operation of the vacuum pumps.It can be concluded that the vacuum degree of the condenser has optimization potential during summer.It also proposes optimization about the pump operation mode.
