Abstract: In order to fulfill the Nuclear Power Plant（NPP） general operation requirement,the purpose of NPP general operation display function design is to integrate the DCS system information reasonably.A NPP general operation display function design method and related design example are provided in this paper,from the point of view of operation.And this paper also gives a preliminary analysis on the advantage of the design method.With this design method,the operator can get the DCS information flexibly,quickly and completely,and the safety and availability of NPP can be improved by this method.
