Abstract

An integrated control logic device and an operating method thereof adjust a position of a main control valve and a position of an auxiliary control valve. In particular, the position of the auxiliary control valve is adjusted by determining whether a change in the position of the main control valve is in a preset deadband range, thereby preventing a periodic water level fluctuation of a steam generator of a nuclear power plant.
