Abstract: In inland nuclear power plant adopted re-recycle water cooling system in conventional island, the water consuming is approximately double of the thermal power plant with the same capacity. When dry cooling technology is adopted, the water consuming is same with the coastal nuclear power plant, and the fuel do not increase which is always happed in the thermal power plant cause of the backpressure. The research of the applying dry cooling technology in inland nuclear power plant is urgent with good prospects. This paper focuses on the construction of AP1000 nuclear power plant in water lacking district inland, analyses the using of indirect dry cooling system, proposes some suggestions for the engineering practice.

Key words: indirect dry cooling system, lack of water region, conventional island, application
