Abstract
An auxiliary feedwater valve control apparatus (1) of a steam generator (103) that operates an auxiliary feedwater valve (123) in an auxiliary feed water system provided as a protective system of a main feed water system that feeds secondary cooling water to a steam generator (103), includes a water-level detection means (125) that detects a water level of secondary cooling water in the steam generator (103), a water-level-deviation calculation means (3) that calculates a deviation between a preset target water level and a water level detected by the water-level detection means (125), a valve-operation setting means (4) that sets an aperture of the auxiliary feedwater valve (123) corresponding to a deviation of the water level, and a valve drive means (5) that outputs a signal for driving the auxiliary feedwater valve (123) corresponding to setting by the valve-operation setting means (4).
