PROBLEM TO BE SOLVED: To provide a circulating water pump control system and a circulating water pump control method capable of suppressing unnecessary power consumption and suppressing economical loss by adjusting a rotating speed of a motor that drives a circulating water pump of a nuclear power plant.SOLUTION: A circulating water pump control system comprises: a condenser 1 which condenses steam generated in a nuclear power plant 100 by heat exchange between the steam and cooling water; a circulating water pump 3 which supplies the cooling water to the condenser 1 from a cooling water source where the cooling water used in the condenser 1 is stored; a flow meter 6 which is disposed in a feed water route 4 for feeding the cooling water from the circulating water pump 3 to the condenser 1 and which measures a flow rate of the cooling water fed from the circulating water pump 3 to the condenser 1; and a control unit 8 which controls a rotating speed of a circulating-water-pump drive device 7 which drives the circulating water pump 3 on the basis of a measuring result of the flow meter 6 and which controls a quantity of the cooling water fed from the circulating water pump 3 to the condenser 1.SELECTED DRAWING: Figure 1
