功能设备组(FEG)是将具有相同隔离特征、完成同一功能的所有设备放在同一个组内.通过FEG可以将具备同一隔离范围内的所有维修工作安排在同一停役窗口实施,避免重复停役,减少停役维修造成的系统或设备不可用时间.随着FEG在国内外越来越多的电厂得到推广,秦山核电也正式开展了FEG的建设工作.本文首先详细介绍了秦山核电FEG的建设及应用过程,再对功能设备组在核电厂管理提升应用方面进行了探索,并进一步阐述了功能设备组在制定长周期循环计划、优化预防性维修、优化停役窗口、减少运行负担、提高计划工作效率、减少维修工作对机组运行的影响和提高设备可靠性等方面具有非常重要意义.FEG的运用使核电站的人力及资源得到更优化的分配和利用.

Functional equipment group (FEG) puts the equipment with the same isolation characteristics and functions into the same group. Through the FEG, all maintenance with the same isolation scope can be arranged in the same shutdown window, avoiding repeated shutdown and reducing the system or equipment unavailability caused by the shutdown maintenance. With the expansion of FEG in more and more power plants, Qinshan Nuclear Power Plant has also formally constructed FEG. This paper introduces the construction and application process of the FEG in Qinshan Nuclear Power Plant, explores the application of the FEG in the management promotion of nuclear power plant, and expounds the importance of the FEG on formulating long-term cycle plan, optimizing preventive maintenance, optimizing shutdown window, reducing operation burden, improving efficiency of planed work, reducing the influence of maintenance work on unit operation, and improving the reliability of the equipment. The utilization of the FEG can optimize the allocation and utilization of manpower and resources in nuclear power plants.
