PROBLEM TO BE SOLVED: To provide a water supply control apparatus capable of continuously controlling a water supply pump even on any output stage of a nuclear reactor while taking problems into account. SOLUTION: The present invention relates to a nuclear reactor water supply control apparatus including: a main control section 2 for generating a water supply flow rate request signal S4 on the basis of a nuclear reactor water level signal S1, a nuclear reactor water supply flow rate signal S2 and a main steam flow rate signal S3; and an individual control section 3A which issues a water supply pump control command S5 to each water supply pump on the basis of the water supply flow rate request signal S4. A thermal output corresponding signal of a nuclear reactor is inputted to the individual control section 3A. Thus, even if the output is suddenly reduced, a water supply flow rate can be decreased without opening a water supply pump trip or re-circulation valve, thereby suppressing an unnecessary water level change.
