The inventive nuclear plant (1) comprises a containment shell (2) provided with a decompressing pipe (6) connected thereto in which a blowing device (34) and a Venturi washer (12) placed in a container (14) with a washing liquid (W) are in series arranged. According to said invention, even finest particles or aerosols carried by air are highly reliably held in the Venturi washer (12) and the release thereof in environment is excluded in a particularly reliable manner in the case of decompression even associated with seal failures. For this purpose, the size of the blowing device (34) and the Venturi washer (12) are selected in such a way that during the operation of the blowing device (34) a flow rate of liquid in the Venturi washer flowing to the decompressing pipe (6) is higher than 130m/sec, preferably higher tan 180m/sec. |
