ABSTRACT:
A nuclear power plant includes a containment for the retention of radioactivity having an overpressure safety outlet. A filter connected to the outlet includes a vessel for receiving a scrubbing liquid up to a given liquid level, a venturi scrubber disposed in the vessel having an outlet disposed above the given liquid level, an impact plate disposed at the outlet of the venturi scrubber for mist collection, a metal-fiber filter downstream of the venturi scrubber having at least first and second layers with a thickness of from 10 to 20 mm, the first layer being a moisture collector with a fiber thickness of from 8 to 20.mu. and the second layer being an aerosol collector with a fiber thickness of from 2 to 7.mu., and a mist collector downstream of the metal-fiber filter. The vessel has a top with a gas outlet downstream of the mist collector. A stack is connected to the gas outlet and leads to the atmosphere.
