Abstract
The device is suitable for use in inspecting the tubular plate of a steam generator, for instance of a PWR, comprising parallel banks of tubes contained in an enclosure having at least one access hole situated opposite an interval between two adjacent ones of said banks, the device comprises an elongated hollow member having a cross section whose transversal size is less than the interval for insertion into the enclosure through the access hole. A light guide and an endoscope are located inside and along said hollow member, with the endoscope being under the light guide; first and second light deflection mirrors are associated with the guide and endoscope for scanning purpose. A fixed lighting source illuminates the zone in which the light beam from the first deflection mirror is cut by the second deflection mirror.
