Abstract: The insertion device comprises a guide collar (75) provided at one of its ends with means (77) for connection to corresponding means (87) arranged at a first end of an extraction sleeve tube (85), a retention collar (100) provided at one of its ends with detachable means for connection to corresponding means arranged at the second end of the extraction sleeve tube (85) and means for fastening the retention collar (100) to the entrance face (3a) of the tubular plate (3). The device also comprises means for positioning the extraction sleeve tube (85) and for positioning and controlling and extracting a syringe for injecting glue comprising an operating member (17) and an elongated transmission element (18) connected at one of its ends to the injection syringe and at its other end to the operating member (17). The extraction sleeve tube (85) can be connected to the guide collar (75) and to the retention collar (100) in order to be positioned inside the tube (5) which is being extracted. The syringe for injecting glue is arranged inside the sleeve tube (85) and controlled manually via the operating member (17) and the flexible transmission element (18). The invention also relates to a method for extracting a portion of a generator tube at a distance from the ends of the tube. … …

Abstract: The peening is carried out by means of a device comprising an outer casing (5) of tubular shape which is placed so as to bear against one face of the tubular plate around one flush end of the tube to be peened. A tool comprising a shot-spraying nozzle is mounted so as to be able to move axially in the outer casing (5). The control device comprises at least one piezoelectric sensor (20) arranged in contact with the wall of the outer casing (5), and means (23, 24) for measuring the electric signal generated in the sensor (20). The shot-spraying nozzle is brought into the outer casing (5) in the region of the sensors (20) after each operation of peening a tube. The electric voltage of the signals produced by the sensors is measured. … …

Abstract: A sleeve (8) is introduced inside the tube (3) from the face (1a) of the tube plate, with which the tube (3) is flush, through the entire length of the tube plate (1). The tube (3) and the sleeve (8) are joined together in two zones (15, 16) by means of a binder which ensures a bond of high mechanical strength. An axial pull is exerted on the sleeve (8) from the face (1a) of the tube plate (1). The device is capable of pulling on the sleeve which operates either continuously or in steps.

Abstract: The heating element (14) is in the form of a helical winding (31) made of a resistance heating wire which constitutes the central core of a coaxial cable (32) having a tubular metallic outer sheath and an insulating material interposed between the central core and the outer sheath. The coaxial cable (32) constitutes a helical winding (31). The apparatus can be used in particular for the heat treatment of the small bends of a bundle of tubes in a steam generator in a pressurized water nuclear reactor.
