Fracture Mechanics Analysis of Flaw in Outlet Nozzle of RPV
-
摘要: 采用断裂力学分析方法,对大亚湾核电站反应堆压力容器出口接管管嘴上的一些缺陷进行了疲劳裂纹扩展分析和快速断裂力学分析,且依据规范对计算结果进行了评定,结果表明:此缺陷不会影响安全。Abstract: This paper describes the fatigue crack propagation analysis and fast fracture mechanics analysis for the flaw in the outlet nozzle of Reactor Pressure Vessel(RPV) in Daya-bay Nuclear Power Station, using fracture mechanics analysis method. The calculation result is evaluated by the code, and it indicates there is no risk in outlet nozzle with the flaw.
