核电厂冷却水系统热工水力仿真研究

Research on Thermal Hydraulic Simulation of Cooling Water System in Nuclear Power Plant

传统的阻力计算方法已经无法完成核电厂冷却水系统的测试及流量分配,也无法对运行模式进行准确的仿真论证,为此,文章提出核电站系统热工水力模型,并采用一维流体管网系统软件进行仿真验证,结果显示,该仿真建模方法更适用于核电厂的管网系统。

The traditional resistance calculation method cannot complete the test and flow distribution of the cooling water system of the nuclear power plant,nor can it accurately simulate the operation mode.To this end,a thermal hydraulic model of the nuclear power plant system was proposed,and one-dimensional fluid pipe network system software was used for simulation verification.The results showed that the simulation modeling method was more suitable for the nuclear power plant network system.
