    Abstract: Le dispositif comporte un moyen de manutention 21 connu en lui-même disposé à l'intérieur de la boîte à eau du générateur de vapeur et permettant de placer l'ensemble de pose et d'extraction de bouchon 22 dans l'alignement des tubes du faisceau du générateur de vapeur. Le dispositif comporte de plus un moyen de déplacement 35 dans la direction axiale des tubes fixé sur le moyen de manutention 21, un support 44 fixé sur le moyen de déplacement 35, mobile dans la direction axiale, un organe de liaison 51 porté par le support 44 ayant des moyens de fixation amovible au corps du bouchon, et une tige coulissante 55 actionnée par un vérin solidaire du support 44. Le dispositif comporte également un moyen 40 d'amenée et d'évacuation des bouchons. La tige 55 actionnée par le vérin permet en particulier d'exercer une poussée sur le bouchon maintenu par l'organe de liaison 51, pour réaliser son extension et faciliter son extraction.

    Abstract: The irradiated component (1) comprises at least one tubular wall with its axis vertical and fastened inside a well (2) in a concrete structure (3). The connecting elements between the concrete structure (3) and the component (1) are destroyed, the component (1) is displaced in successive steps in the vertical direction along its axis on the inside of the well (2), and the wall of the component is cut, so as to obtain blocks (26) of irradiated material of the wall, at the upper level of the well (2) of the concrete structure (3) after each displacement of the component (1). The cut blocks (26) are disposed of for the purpose of elimination or storage. The displacement of the component can be obtained by a pull or push on its lower bottom.

    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: For the purpose of compressing by hammering a steam generator tube, there is directed a stream of gas at high velocity charged with particles having a particle size of between 50 and 500.10-6 m, onto the inner surface of the tube. The jet of gas is directed onto the inner surface of the tube in radial directions and onto the whole of the periphery of the tube. The flow of the mass of the particles is higher than 0.008 kg/sec for tubes having an inside diameter of around 0.020 m. The device comprises a flexible sheath movable inside a case fixed in a sealed manner under the tube plate around the tube. An injection nozzle is disposed at the end of the sheath receiving the gas charged with particles.
