A water supply system for a nuclear power plant, characterized in that the water supply system is equipped with a device that maintains the water supply capacity for a predetermined period of time or longer for the capacity to decrease. (2) Scope of Utility Model Registration Claim 1, characterized in that the device that makes the passage time longer than the specified time for the radioactivity contained in the water supply to decrease is a drain tank that has a passage time longer than the specified time. Water supply equipment for the nuclear power plant described. (3) A request for utility model registration where the device whose passage time is longer than the specified time for the radioactivity contained in the water supply to decrease is characterized by piping having a thickness and length that requires a passage time longer than the specified time. A nuclear power plant water supply system according to item 1.
