A system for dissipating heat from the interior space (50) of an containment structure (3,6) for a nuclear reactor (2), for an indefinite time period, comprises a first heat exchanger (15,15') outside said containment structure (3,6) which is submerged vertically in a pool (11) associated with the exterior of the top wall (4,7) of the structure (3,6), and a second heat exchanger (25) placed in the interior space (50), said first and second heat exchangers (15,25) being fluid connected to each other in a closed loop circuit (28) with piping (23,24) containment a thermal carrier fluid. Said pool (11) is provided with a covering (90) defining a first duct (12) in communication with an outside air intake, and a second duct (13) in communication with a chimney (14), the interconnection of said ducts (12,13) being inhibited by the water present in the pool (11) when filled to a predetermined level (9). <IMAGE> |
