According to the characteristics of smal modular reactors, the new wet cooling system is proposed for the first time, and the corresponding structure, different types and operation mode are introduced. For the operating characteristics of the new wet cool-ing system, the mathematical model of heat load proportional distribution for the concurrent part and the cycle part is established. Combined with ACP100 smal modular reactors of a power plant, by analyzing thermodynamic property of new wet cooling system, the cooling load percentage changes of the concurrent part have a significant effect on the flow of the cycle part, the inlet water tem-perature of condenser, and the pressure of condenser, the net incremental power. The result of the study shows that power con-sumption of the circulating water pump ( CWP) is not only affected by the CWP operation mode, but also related to the operation mode of the new wet cooling system, and the cooling load percentage of the concurrent part, so that the optimization method of the new wet cooling system is applied to calculating the CWP power consumption.
