PROBLEM TO BE SOLVED: To provide a reactor feed water controller in a short time, capable of suppressing fluctuations of water level due to disturbance of feed water, at operation stoppage and switching of feed water pump and switching the feed water pump. SOLUTION: A correction signal generator 20 is provided for generating correction signal which varies in a ramp form with a variation rate based on the horizontal difference of levels between actual reactor water and set value after varying stepwise during stopping and switching feed water pumps 17A, 17B (TD-RFP), 18A and 18B (MD-RFP) and the signal is added to the feed water demand signal of a main water level controller 16.
