摘　　要：控制棒驱动机构是反应堆本体中唯一的能动设备,其运行的可靠性对反应堆的反应性控制具有重要的作用。本文在介绍失效模式及影响分析(FMEA)方法的基础上,以我国新设计的反应堆控制棒驱动机构为对象,使用该方法进行可靠性评价。评价结果明确了各设备部件的失效原因和失效模式,确定了各部件的严重性等级和风险等级,为今后控制棒驱动机构的可靠性管理提供支持。The control rod drive mechanism is the only active equipment in the reactor, and its reliability plays an important role in the reactivity control of the reactor. Based on the introduction of failure mode and effect analysis （FMEA） method, this paper applies this method to evaluate the reliability of the new design control rod drive mechanism. The evaluation results clarify the failure reasons and failure modes of various components, and determine the severity level and risk level of every component. Furthermore, the reliability analysis can provide support for the reliability management of the control rod drive mechanism in the future.
