摘要：

In the cold area, it is necessary to conduct a research on anti-ice design for nuclear power plant during the winter diversion process. Using cooling water of the power station is an ideal method to raise the water temperature in the diversion channel. In this paper, the phase transition temperature band method is proposed for the turbulence condition. Through the research, it is found that the key to melting ice efficiency is to extend the mixing time. Thus, to improve the ice melting efficiency, optimization has been carried out in two aspects of structure and operation, facilitating the mixing position of hot and cold water to move upstream and extending the mixing time of them. In the present example, the ice-cooling efficiency of the cooling water increases with the increase of the ice concentration. When the ice concentration is 0.84%, the corresponding ice-melting efficiency is 30%. © 2017, China Water Power Press. All right reserved.
