Construction and Application of Functional Equipment Group in Qinshan Nuclear Power Plant

Abstract

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.
