利用以可靠性为中心的维修(RCM)分析方法,优化大亚湾核电站循环水泵的维修策略,给出其全面解体检查周期.优化后的解体检查周期远远超过供货商建议的周期(8 a)和国内外同类设备的周期,可有效节约维修成本,并减少与维修活动相关的人因故障.

This evaluation model for economic benefit of Reliability-centered Maintenance (RCM) is the first time at home and abroad to be applied systemically, completely, simply and effectively to evaluate the maintenance optimization results of a nuclear power station. The paper explains the contents of economic benefits and their classification, then gives detailed explanations of how benefits are evaluated for elimination of tasks and for both the evident and the hidden benefits of newly created tasks, along with examples of this model as applied at Daya Bay Nuclear Power Station.
