<p>The technical problem to be solved is the retention of fission products, in particular aerosols containing fissile material, contained in hot steam/gas mixtures at an overpressure which are postulated to occur in the event of defective operation and are present inside the containment vessel, and the release of the purified mixed gas stream to the atmosphere. To this end, a pressure vessel (FDK) has at least one candle-type filter insert (5, 3) in its interior, an inlet nozzle (2.2) for the mixed gas stream to be filtered on the intake side of the candle-type filters (5), an outlet nozzle (1.2) for the purified mixed gas stream on the outflow side of the filters (5), and piping with shut-off and pressure-relief devices connected to the inlet and outlet nozzles for the mixed gas stream. In the interior of the vessel, a droplet-type water separator (6) is advantageously arranged in the flow path of the mixed gases between the inlet nozzle (2.2) and the intake side of the filters (5) and a condensate collector with a condensate outlet nozzle (8) is advantageously arranged below the droplet-type water separator (6).</p> |
