核电厂设备可靠性管理分级实践

通过核电厂液体区域控制系统的试点分级实践,对《核电厂设备可靠性管理分级导则》进行实例解析,并根据分级实践经验对＂导则＂进行了说明和补充,同时介绍了分级的操作方法、流程。从液体区域控制系统中选出具有代表性的设备进行分级实例介绍,阐述分级工作中应该注意的问题。最后介绍美国核电厂分级后各级设备所占比重,对核电厂的设备分级和可靠性管理工作提供借鉴。

Nuclear power plant equipment reliability management practice

After the practice of nuclear plant components function classification, explaining and supplying the guideline of《Classification Management for components of Nuclear Plant》are presented. Also this paper introduces how to classification components and the classification flowchart. Through the classification of Liquid Zone Control system, it lists the problems which should be avoided. At last, which introduces the proportion of each level equipments,it should be useful for equipments classification and equipment reliability management.
