Abstract: The structure (1) of sleeves and plates which encloses the core of a pressurised water-cooled nuclear reactor is dismantled by cutting while immersed in the pond (9) adjoining the reactor vessel (8). The less radioactive sections are placed in containers (27) of the type used to carry reactor guide tubes when these are replaced, and the more radioactive sections are placed in containers (28) of the type used to carry fuel assemblies. Containers (27,28) are removed from the pool separately. Also claimed is the cutting equipment used in the pool.

Abstract: In order to repair the tapping (2b) of a tapped opening (2) of large diameter, a threaded insert is introduced by screwing into the tapped opening. The threaded insert is introduced into the tapped opening (2) wound on a threaded section of the surface of a drum which is screwed inside a tapped centring ring engaged in the entrance section (2a) of the tapped opening (2). The threaded insert is placed firmly against the tapping (2b) and the threaded insert is fixed firmly in place by fitting a pin traversing the threaded insert and engaged in the wall of the tapped opening (2). The invention also relates to tools allowing the use of the method according to the invention. The method according to the invention applies in particular to the repair of tappings in openings (2) machined in the tank flange (1) of a pressurized water nuclear reactor and allowing the sealed fixing of the tank cover by means of studs. … …

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.
