PROBLEM TO BE SOLVED: To provide a containment spray control device capable of suppressing automatically increase of a pressure and a temperature in a nuclear reactor containment in a core reflooding process at the loss time of a nuclear reactor coolant in a nuclear power plant. SOLUTION: A nuclear reactor containment pressure high signal 27 and a reactor water level below-TAF signal 28 are received by a signal reception part 29, and a condensate-replenishing water pump 18 or a fire-fighting system pump 21 which is an alternative water injecting facility is driven by realization of a logic condition in a control part, and an alternative water injecting facility delivery valve 19, a dry well spray injection isolation valve 13 and a dry well spray flow adjusting valve 14 are opened, to thereby spray water in a condensate storage tank 20 or a filtrate tank 22 into a nuclear reactor containment dry well 3.
