| 摘 要： | 动力堆的年非计划停堆次数是衡量其运行性能的一个重要指标。控制棒水力驱动系统是核供热堆的关键系统之一 ,其运行失效将直接导致供热堆的非计划停堆。运用故障树分析的方法 ,建立以“控制棒非计划下落”为顶事件的故障树 ,分析计算系统各组成单元失效造成控制棒下落、引起非计划停堆顶事件的发生概率 ,并从提高系统运行可靠性的角度出发 ,根据故障树分析的结果 ,提出设计改进意见。

| Abstract: | Unplanned outage times per year is an important indicator of operation performance for power reactor.The hydraulic system of control rod drives is one of the key systems in a nuclear heating reactor.The unplanned outage will be directly caused by the system failure.The unplanned outage caused by the failure of components in the system will be discussed with the method of fault tree analysis.The issues will be concentrated on the setup of the fault tree,analyzing the probability of topmost event and giving some suggestions on improving the system design based on the fault tree analysis result. |
