摘　　要：从1992年至2012年的我国核电厂以及其他国家核电厂的运行事件资料中,收集了17起与控制棒组件及其驱动机构相关的异常事件,对其进行了统计和分类,并分析了控制棒肿胀或燃料组件变形的影响、驱动机构焊缝的泄漏或渗漏、控制棒棒控系统的可靠性几个重要问题,提出了一些经验反馈的建议。Seventeen operational events of the control rod assembly and its drive mechanism are collected from 1992 to 2012 important nuclear operational events and feedback in referred nuclear power plants. After investigated and classified, several important issues, such as the impact of control rod swell and fuel assembly distortion, control rod drive mechanism leakage, and the control system reliability of control rod, are emphatically analyzed. Some suggestions of experience feedback are proposed.
