As the main branch, equipment reliability management is considered as an effective approach to make plant management strategy and organize routine work. Some achievements on research and application of equipment reliability management at Daya Bay Nuclear Power Station are introduced in this paper. By studying and implementing 1NPO （Institute of Nuclear Power Operations） AP-913 equipment reliability process, reliability-centered maintenance （RCM）, critical component management （CCM）, and many other similar methods, equipment reliability management system has been established at Daya Bay. And by continuous effort on improving application effect of these technologies, some innovation has also been made. Some innovative products, such as iSOM Intelligent Expert System, reliability and technique centered maintenance （RtCM）, predictive maintenance system （PdM）, and so on, have been developed. Based on these achievements, Daya Bay Nuclear Power Station has achieved excellent operation performance and won several prizes in WANO （World Association of Nuclear Operators） competition every year.展开更多

In order to improve the reliability automatic capping device, the equipment function and machine structure are analyzed. And Failure Mode and Effects Analysis （FMEA） method is applied to systematically analyze all possible failure modes and their reliability. Through establishing the FMEA worksheet, all failure causes, failure effects and their severity are analyzed comprehensively. Base on these analyzing resuhs, it is easy to find out the product function design defects and weak links. Finally, through putting forward design prevention and improvement measures in design, the mission reliability of automatic capping device is improved, and most serious failure mode occurrence is avoided efficiently. Thus the safety operation of TES has been guaranteed in technology.展开更多
