PROBLEM TO BE SOLVED: To improve readiness of control.SOLUTION: In nuclear facilities 1 that generate steam from a secondary coolant of a steam generator 4 by heat exchange between the secondary coolant in the steam generator 4 and a primary coolant output from a reactor coolant system 100, a feed-water control device 51 for controlling a water supply device 40 includes: a feed-water pipe 14 connected to the steam generator 4 so as to feed the secondary coolant towards the steam generator 4; and a feed-water valve 42 provided in the feed-water pipe 14. The feed-water control device sets a valve opening of the feed-water valve 42 on the basis of an output state of a reactor 2. |
