摘要
通过对AP1000核电厂厂用水系统进行故障模式及影响分析(FMEA)以及逻辑决断分析(LTA),深入了解该系统工艺及相关设备的功能故障、故障模式和影响,进而建立优化的维修决策。与现行的维修策略相比,经由可靠性为中心的维修(RCM)优化所得的维修策略对显性故障更多的是选择状态监测/定期维护,而对隐蔽性故障则采用定期试验。
Reliability centered maintenance（RCM） methodology has been applied to a service water system in AP1000 nuclear power plant.Using the functional failure modes and effect analysis（FMEA） and logic tree analysis（LTA）,the optimized maintenance strategy is established based on a better understanding of the relevant information on this system and related equipments（including the functional failures,failure modes and effects）conclude.Compared with the current maintenance strategy,this maintenance strategy optimized by RCM conducts the condition monitoring and periodical maintenance for dominant failures but conducts periodical test for the recessive failures.
