Title:
PRESSURE SUPPRESSION POOL APPARATUS AND NUCLEAR REACTOR
Document Type and Number:
WIPO Patent Application WO/2023/070943
Kind Code:
A1
Abstract:
A pressure suppression pool apparatus and a nuclear reactor. The pressure suppression pool apparatus comprises a housing (1) and at least one hollow pressure suppression pipe (2); a closed cavity and a plurality of baffles (3) for slowing gas flow are provided in the housing (1); the cavity is filled with a cooling liquid (11); the baffles (3) are submerged in the cooling liquid (11); an accommodating space (12) for accommodating gas is provided on the cooling liquid (11) inside the cavity; the pressure suppression pipe (2) passes through the outer wall of the housing (1), and comprises an out-of-housing section (21) located outside the housing (1) and an in-housing section (22) located in the housing (1); an end portion of the in-housing section (22) is inserted into the cooling liquid (11), and the out-of-housing section (21) is connected to the gas in an environment. The present pressure suppression pool apparatus is a passive system, has high safety and reliability, high cooling efficiency, and a significant pressure suppression effect, can effectively suppress the rise of the pressure and temperature of a containment under predetermined working conditions, and has low volume requirements for the space (12) and the cooling liquid (11).
