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: Before lifting the upper reactor internals (5) out of the reactor tank (1), a rod (17) carrying a wave emitter-receiver (18) at its lower end is introduced into a guide tube (13a). After lifting the upper internals a short specified distance, the emitter-receiver is activated to emit waves towards the internal surface of the tank, and rotated about a vertical axis. The waves reflected by the core envelope (16) or by any obstacle are received, and the reflected signal is analysed to determine the presence of obstacles such as fuel assemblies (15) or control clusters hooked underneath the upper internals.

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. … …
