The invention relates to a nuclear facility, in particular a nuclear power plant (4), comprising a containment (8) and a venting system (2) for relieving pressure of the containment (8) in a filteredmanner, wherein the venting system (2) has a venting line (28) that leads out of the containment (8) into the surrounding area and into which a wet scrubber (12) is connected for the venting flow (10)that occurs upon venting, the wet scrubber (12) has a pool (26) which is already filled with a scrubbing liquid (18) in the standby state prior to the venting process and over which a gas chamber (48) is located, the venting line (28) comprises an inlet line (14) which leads into the wet scrubber (12) for the venting flow (10), said inlet line branching into a number of outlet nozzles (38) in a distributor (34), and the outlet nozzles (38) are at least partly immersed into the scrubbing liquid (18) in the pool (26). The aim of the invention is to further develop such a venting system (2) suchthat critical concentrations of combustible gas mixtures are prevented in all operating states in a more reliable manner than before while maintaining a low degree of equipment and processing complexity. According to the invention, this is achieved in that at least one separate outlet opening (56) is provided which is connected to the inlet line (14) or to the distributor (34) via a branch line (54, 90) and which is thermally insulated from the scrubbing liquid (18) in the pool (26) at least in the standby state.
