The reliability and economy of the thermal performance of the second circuit of nuclear power units are becoming the focus of nuclear power operation evaluation and analysis. Based on the thermodynamic mechanism and design data set, this paper develops a steady-state calculation module for the second circuit of nuclear power of an M310 unit, and implements the overall thermal calculation of the system by entering the initial and final parameters of the steam turbine and a small number of constraints, and finally obtains the detailed thermal parameters and performance indicators of the system. Based on this module, the calculation of the second-circuit thermal system of nuclear power units and the calculation and analysis of variable working conditions can be realized, which provides a theoretical basis for the subsequent software development of thermal performance supervision platform and other software.
