| 摘要 |
The invention relates to a nuclear system (1) comprising a reactor containment (2) which is connected to a decompression line (6), wherein a Venturi washer (12), which is arranged in a container (14) containing a washing liquid (W), and a throttling device (24) are serially mounted. The aim of the invention is to restrain, with particularly high reliability, fine air-transported activities or aerosols during decompression such that release thereof into the environment is practically impossible. The inventive Venturi washer (12) and the throttling device (24) are dimensioned in such a way that, in the case of a critical drop in pressure of an air-vapour mixture flowing in the decompression line (16), a flow speed of said air-vapour mixture of more than 150m/s, preferably more than 200m/s, can be adjusted with respect to the throttling device (24) in the Venturi washer (12).
