Calculation and Analysis for the Thermal Performance of Horizontal Steam Generator in Nuclear Power Plant

Based on the operational principle and structure characteristics of horizontal steam generator, the mathematical model has been established and the thermal hydraulic program has been developed for horizontal steam generator. Based on the design parameters of horizontal steam generator of nuclear power plant in service, the program is checked. The program can be used to study the distribution of thermal parameters in horizontal steam generator, and to provide guidance for horizontal steam generator design and safety analysis. In addition, ac-cording to the historical operational data of nuclear power plant in service, the program can be used to analyze the thermal performance of horizontal steam generator at present stage, and predict the thermal performance in a period of time.
