    Abstract: The body (4) of the plug (3) is rebored in the direction of its end wall (6) and the clamp block (7) is drilled by an electric machining process, over a substantial part of the length of the plug. The wall of the plug body (4) is relieved of stress with the aid of a welding torch introduced into the bore made by electric machining, and a gripping tool is introduced into the bore in order to extract from the tube the plug body (4) which has been relieved of stress.

    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.

    Abstract: The device comprises a handling arm (21) arranged inside the water box of the steam generator and permitting the assembly for fitting and withdrawing a plug (22) to be placed in the alignment of the tubes of the steam generator bundle. The device additionally comprises an endless screw (35) for moving the tubes in the axial direction, which is fastened to the handling arm (21), a support (44) fastened to the endless screw (35), movable in the axial direction, a linking member (51) carried by the support (44) for removable fastening to the plug body, and a sliding rod (55) actuated by a jack integral with the support (44). The rod (55) actuated by the jack permits, a thrust to be exerted on the plug held by the connecting member (51), in order to produce its extension and facilitate its withdrawal.

    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. … …
