Abstract: Société dite : FRAMATOME Procédé et dispositifs d'extraction d'un bouchon d'obturation d'un tube de générateur de vapeur DU CONTENU TECHNIQUE DE L'INVENTION On effectue un réalésage du corps (4) du bouchon (3) en direction de son fond (6) et un perçage de la noix de serrage (7), par procédé d'usinage électrique, sur une partie substantielle de la longueur du bouchon. On réalise le détensionnement de la paroi du corps (4) du bouchon à l'aide d une torche de soudage introduite dans l'alésage réalise par usinage électrique et on introduit un outil de préhension dans l'alésage pour extraire du tube le corps (4) du bouchon détensionné. L'invention est également relative aux dispositifs permettant de réaliser l'extraction par le procédé suivant l'invention. Figure 2.

Abstract: The process, for use on a pressurized water reactor (PWR) that is shut down and cool, comprises raising the core top plate (4a) with lifting and handling equipment in a pond above the core vessel (1). When a fuel assembly remains attached to the top plate, a fuel assembly holder (22) is lowered into a position where it holds the fuel assembly onto the top plate while it is transferred to a receiver (15) within the pond. The holder is then released, and the fuel assembly is deposited in the receiver, if necessary after cutting its centering pin.

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.
