Abstract

In the decontamination of pipelines and water chambers of a steam generator in a pressurized-water reactor installation, it must be possible for the pipelines to be sealed. It is possible to seal pipelines with an inflatable sealing plug placed in the pipeline. In order to be capable of determining whether a sealing arrangement 1 in the pipeline 2 of the steam generator is correctly positioned when decontamination is carried out, the sealing arrangement is provided with one or more contact detectors 3. These consist of non-conductive elastic bands 3 surrounding separate conductive elements 4, 6 which form part of an electric circuit for registering any contact. <IMAGE>
