摘要
A nuclear power plant (4) comprises a Containment (8) and a filtered Containment venting System (2), • the filtered Containment venting System (2) comprising a pressure relief line (10) leading from inside the Containment (8) to the outside, • a catalytic recombiner (20) for hydrogen removal being located at or shortly after the inlet (12) of the pressure relief line (10) and, further downstream, a wet scrubber (48) being switched into the pressure relief line (10), • the wet scrubber (48) being located inside the Containment (8) and comprising a washing liquid compartment (50) for a washing liquid (54) in it and a gas dome (52) above it, such that during venting Operation a venting stream is washed by the washing liquid (54) and then enters the gas dome (52), • the gas dome (52) being hermetically sealed against the Containment atmosphere (110). It is an objective of the present invention to provide a filtered Containment venting System (2) of the above mentioned type which avoids the risk of the wet scrubber (4) running dry during venting Operation. Therefore, according to the invention the washing liquid compartment (50) is part of a larger reservoir (68) located inside the Containment (8), wherein the washing liquid compartment (50) is in flow communication with the rest of the reservoir (68) such that washing liquid (54) lost in the washing liquid compartment (50) due to evaporation is automatically replenished by a liquid (70) in the reservoir (68).
