AP1000核电厂设备可靠性分级方法的特点与应用研究

Characteristics and Application Study of AP1000 NPPs Equipment Reliability Classification Method

非能动百万千瓦级先进压水堆(AP1000)核电厂采用一种集成的方法建立设备的可靠性分级,包括概率风险分析技术(PRA)的应用,维修规则(MR)管理,生产发电设备可靠性分级,设备功能组(FEG)的划分等,最终将设备可靠性分为4个级别,在分级流程和结论上与传统以可靠性为中心的维修技术(RCM)和流程化的RCM(SRCM)有较大区别。本文分析AP1000核电厂设备可靠性分级的特点,提出将RCM与该分级方法相结合开展设备可靠性管理工作的思路。

AP1000 nuclear power plant applies an integrated approach to establish equipment reliability classification, which includes probabilistic risk assessment technique, maintenance rule administrative, power production reliability classification and functional equipment group bounding method, and eventually classify equipment reliability into 4 levels. This classification process and result are very different from classical RCM and streamlined RCM. It studied the characteristic of AP1000 equipment reliability classification approach, considered that equipment reliability classification should effectively support maintenance strategy development and work process control, recommended to use a combined RCM method to establish the future equipment reliability program ofAP 1000 nuclear oower olants.
