Abstract
An apparatus and a method for detecting and locating leaks in a nuclear plant, in particular a pipeline in a nuclear plant, include a collection line which is permeable to a substance to be detected and which communicates with a pump and with a sensor for the substance. The sensor has a detector for detecting the radioactivity of the substance or a branch line which communicates with a detector for detecting radioactivity branches off upstream of the sensor. If a radioactive substance reaches the collection line and penetrates it, then the location of the leak can be determined from the instant at which the radioactive substance reaches the detector.
Claims7
An apparatus for detecting and locating leaks in a nuclear plant, comprising:
- a collection line permeable to a substance to be detected;
- a pump communicating with said collection line;
- a sensor communicating with said collection line for sensing the substance, said sensor not suited to detecting radioactivity of the substance;
- a detector communicating with said collection line for detecting radioactivity of the substance;
- and
- a suction pump associated with said detector.
