Provided is a nanofluid injection device for removing heat from nuclear power plants. According to the present invention, the nanofluid injection device for removing heat from nuclear power plants is to inject nanofluid into a reactor cavity for cooling the core catcher and outer wall of a reactor vessel, when cooling water in a fuel shuffling tank is injected into the reactor cavity when a serious accident of meltdown occurs. The present invention comprises: a reactor vessel installed inside of a containment building and containing nuclear fuel inside; a reactor cavity installed outside of the reactor vessel and containing the reactor vessel inside; one or more nanofluid storage tanks connected with the reactor cavity by a first pipe and storing nanofluid to provide nanofluid to the reactor cavity; and a nitrogen nanofluid storage tank, connected to the nanofluid storage tank by a second pipe, and storing nanofluid while charged with nitrogen gas having certain amount of pressure, for providing the stored nanofluid to the nanofluid storage tank. |
