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 component (1) is moved in successive steps in the vertical direction, to allow cutting of an upper part (16) of the component (1), inside the cavity (pool) (4) of the reactor. First initial raising of the component (1) is carried out by exerting a thrust on the lower part (1a) of the component (1). A first modular support element (33) is introduced between the lower part of the component (1) and a fixed support (27). The component (1) is rested on the first modular support element (33). For each of the subsequent successive steps of moving the component (1), unitary lifting of the component (1) is carried out over a defined vertical distance, using second lifting means (32) bearing on the support (27). A modular support element (33, 33', 33'') is introduced between the modular element (32) by which the lifting is carried out and the fixed support (27). The component (1) is made to bear on the fixed support (27) by means of the superimposed modular elements (33, 33').

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 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: The disassembly and/or the cutting up of each of the components (6) of the internal equipment fastened in the vessel (4) is carried out under water, inside the reactor vessel (4). Metal components (12) separated from the vessel (4) are obtained and are withdrawn successively from the vessel and then compacted under water in a compacting press. The metal components (36) obtained after compacting are deposited under water in a storage and transport container (37). The dismantling device comprises in particular a handling and cutting unit (11) which makes it possible to perform the cutting up of cylindrical sections of the reactor core enclosure (6) and the transporting of the sections (12) into the compacting press (34).

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 irradiated component (1) includes at least one wall of tubular shape arranged with its axis in the vertical direction and fastened inside a pit (2) made in a concrete structure (3). The linkage elements between the concrete structure (3) and the component (1) are removed, the component (1) is moved in successive stages in the vertical direction along its axis, inside the pit (2), the wall of the component is cut up so as to obtain blocks (26) of irradiated material from the wall of the component (1), at the upper level of the pit (2) of the concrete structure (3), after each movement of the component (1). The cut-up blocks (26) are taken away in order to be disposed of or stored.
