研究建立了蒸汽发生器二次侧非能动应急堆芯余热排出系统热工水力特性的物理与数学模型，并编制了计算机程序。以中国秦山核电站的数据为依据，计算和分析了在失去厂外电源事故典型工况下，该系统投入运行时对瞬态热工水力特性的影响。
The physical and mathematical models of the thermal-hydraulic characteristics of the secondary residual heat removal system for the passive side of the steam generator were established and a computer program was compiled. Based on the data of Qinshan Nuclear Power Station in China, the transient thermal-hydraulic characteristics of the system were calculated and analyzed under the typical operating conditions of power plant accidents.
