| 摘 要： | AP1000 核电站常规岛设计必须考虑高能管道断裂的影响。利用应力分析方法和特定位置法对管道断裂位置判定进行了分析；采用流体力学的方法对主蒸汽和主给水管道断裂荷载进行了计算；利用经验公式，结合管道断裂后的几何特性，对AP1000 核电站常规岛主蒸汽管道断裂后端部不受约束和端部受约束两种情况下的主要喷射几何尺寸进行了计算。通过计算，得出了主蒸汽管道断裂后的荷载和主要喷射几何特性。通过计算分析得出结论，常规岛高能管道断裂后荷载和喷射影响范围很大，可以作为高能管道断裂防护设计的依据。

| Abstract: | The effects of high-energy pipe rupture shall be considered in design of AP1000 nuclear power plant’s conventional island. This paper analyzes the rupture locations with stress analytical method and specific location method; calculates the rupture loads for main steam pipe and water-feeding pipe with hydromechanical method; and calculates the jet geometry of the ruptured main steam pipe at full separation and limited separation conditions based on empirical formula. The load and jet geometry of the ruptured main steam pipe are obtained through calculation. It concludes that the influence areas of load and jet are very large after the conventional island’s high-energy pipe is ruptured, which can be used as the basis for rupture-prevention design of the high-energy pipe. |
