Passive cooling structure and reactor building

Abstract

The application relates to a non-active cooling structure and a reactor plant. The cooling structure comprises a base body, a first communication assembly and a second communication assembly; the base body is configured with a cooling cavity and a liquid injection cavity, the cooling cavity is used for being communicated with a containing cavity in a safety shell; the first communication assembly comprises a first liquid injection pipeline and a switch valve, the first liquid injection pipeline is provided with a first inlet and a first outlet, the first inlet is communicated with the liquid injection cavity, the first outlet is used for being communicated with the containing cavity, the height of the first inlet is higher than the height of the first outlet, and the switch valve is installed on the first liquid injection pipeline; the second communication assembly comprises a second liquid injection pipeline and a first pressure switch, the second liquid injection pipeline is provided with a second inlet and a second outlet, the second inlet is communicated with the cooling cavity, the second outlet is communicated with the liquid injection cavity, the height of the second inlet is higher than the height of the second outlet, the first pressure switch is installed on the second liquid injection pipeline, and the first pressure switch is configured to be opened when the pressure value in the cooling cavity reaches a first preset value.
