本発明は、配管または容器等からの流体の漏洩を検知す

く用いられている。[Technical Background of the Invention and Problems thereof] In general, facilities that handle radioactive materials such as nuclear power plants are equipped with a large number of pipes or containers for storing or distributing radioactive waste liquids or chemical solutions. As mentioned above, these piping and containers must be connected to each other in order to distribute or contain radioactive waste liquids or chemical solutions to predetermined locations, and flanges are often used for this connection. ing.
従来、これらのフランジからの漏洩を検知するための実
例がなく、フランジからの漏洩の有無はパトロールにて
確認するという程度であった。Conventionally, there has been no practical example for detecting leakage from these flanges, and the presence or absence of leakage from flanges has only been confirmed by patrolling.
ところで、配管には流体が常時流れているわけでなく、
例え流れているとしても圧力条件等が変われば漏洩が止
まってしまうこともあり、このため流体の成分の付着等
による漏洩の痕跡が残っている場合を除いては、パトロ
ールにて漏洩が発見されることは希である。By the way, fluid does not always flow through the piping.
Even if it is flowing, the leak may stop if the pressure conditions etc. change, so unless there are traces of leakage due to adhesion of fluid components, leakage will not be discovered during patrol. This is rare.
また保温、防露等のカバーが施工されている配管等にお
いては、漏洩の痕跡すら発見できないという不具合があ
った。In addition, there was a problem in that even traces of leakage could not be found in pipes and the like that were covered with heat-insulating, dew-proofing, etc. covers.

あった。On the other hand, an electrode type detector is also considered as a leak detector, but since there are an unspecified number of flanges, it is expensive to install this electrode type detector at all locations, and maintenance is required. Therefore, there was a problem that the radiation exposure of workers increased.
