The invention relates to a safety system for a nuclear facility, comprising a reactor hall (4) provided with a nuclear reactor (1) in a cooling pool (3) of said reactor, characterised in that it comprises a ventilation system, for adjusting the ambient conditions of technical rooms and of the reactor hall and for filtration to protect the environment from gaseous radioactive waste. The system is provided with: a. at least one air inlet (201a) having a variable cross-section in a wall of a building (10), the air inlet opening into an intake treatment room (201) provided with a first air outlet (201b) into the reactor hall; b. a water/air exchanger (5) in the pool, comprising an inlet duct (5a) open in the reactor hall (4); c. an air outlet duct (5b) of the exchanger (5), the duct being suitable for supplying the air leaving the water/air exchanger to an outlet filtration device (203) in communication with a flue (210); d. at least one extractor (202) arranged at the outlet of the air outlet duct (5b) in a room comprising the outlet filtration device (203), and for which, when the extractor is at a standstill, the water/air exchanger and the cross-section of the at least one air inlet (201a) are configured so that, when the reactor is at a standstill, the rise in the temperature of the water in the pool heats the air in the exchanger relative to the outside temperature at the flue outlet and creates an air flow that sucks the outside air at the air inlet in order to eject it at the outlet of the flue through the filtration device (203).
