ENSEMBLE ET PROCEDE DE DETECTION ET DE MESURE DU TAUX DE COLMATAGE DES PASSAGES D'EAU DANS UN CIRCUIT SECONDAIRE D'UN REACTEUR NUCLEAIRE A EAU SOUS PRESSION

摘要

The assembly has a probe (20) comprising an elongated cylindrical body (21) with three magnetic field transmitters (35) i.e. transmitting reel. An assembly of magnetic field detectors i.e. magnetometers, is connected by a connection unit with a signal amplifying and visualizing system that amplifies and visualizes signals emitted by the detectors during displacement of the probe in a tube (5) at a level of a passage (10) to examine spacer plates (8). An independent claim is also included for a method for detecting and measuring a clogging rate.
