Abstract
Cold end optimization is an economic comparison and analysis of the cold end scale of different circulating water system configuration schemes based on design inputs such as specific site parameters, water intake and drainage conditions, environmental requirements, condenser heat load, economic operation period, and electricity price. Provide technical support for water system design. This paper takes one Nuclear Power Plant as an example to analyze the cold end optimization. Based on the introduction of some important equipment performance parameters optimized for the cold end, the main variables and calculation principles of the cold end optimization of the DC cooling circulating water system of the nuclear power plant are analyzed. The effects of different factors on the optimization results of the cold end were discussed, including the economics of optimization variables, the slightly increased power curve, the end difference, and the flow rate of the condenser tube, ineffective hypothermia etc., to provide a reference for the subsequent optimization calculation of the cold end of the DC cooling circulating water system of the nuclear power plant.
