Abstract

This paper introduces the fault analysis of FJS NPP SVDU of the unit control mode, analyzes the reasons and gives corresponding technical solutions. After the implementation of the technical program, this paper analyzes from several aspects: the elimination of 5 groups of KIC/BUP switch logic interlocking switches will not affect the safe operation of the unit. It also avoid the switch of unit control mode to BUM or even the retreat mode of the unit resulting from SVDU failure when the KIC control mode is available.
