摘要： Even a site having a complicated curved surface shape, such as a welded spot on a bottom of a nuclear reactor core, is simply and electrolytically etched without discharging an etching liquid in a large amount, whereby grain boundary on the surface of the nuclear reactor core internals can be confirmed visually.When the surface of nuclear reactor core internals is electrolytically etched, a sponge provided with holes having a communicating structure is integrated with an etching liquid, and the etching liquid is gelled, while the integrated combination is disposed in front of an electrode, followed by the application of voltage to turn on electricity at a state in which said electrode is electrically connected to the cathode of a direct-current power supply, and brought into contact with or approximated to the surface of the core internals electrically connected to the anode of the direct-current power supply.

摘要： An underwater remote inspection device is provided with an etching device and a magnifying observation device mounted to a supporting member. A chamber of the etching device is provided with a negative electrode, a positive electrode and a sealing device, and is connected to an etchant supply pipe and an etchant exhaust pipe. A single pair of annular sealing members of the sealing device is provided to a distal end portion of the chamber. A suction passage formed in the side wall of the chamber communicates to a sealing region formed between the sealing members. The magnifying observation device is provided with a magnifying camera in a waterproof container and a plurality of LED lights are installed to the waterproof container. The underwater remote inspection apparatus can prevent leakage of an etchant and reduce execution time of etching.

摘要： A access apparatus is set on instrumentation nozzles penetrating a bottom portion of a reactor pressure vessel, in the reactor pressure vessel filling water. The access apparatus has an arm turned, and a mounting fixture that can move along the arm and having a holding member. A cover apparatus having a guide pipe covers the access apparatus, and is installed on the bottom portion in underwater environment in the reactor pressure vessel. The water below the cover apparatus is drained from the reactor pressure vessel to form an air space below the cover apparatus. A variety of device heads is suspended and lowered in the air space through the guide pipe, and mounted to the holding member of the mounting fixture. Repair or preventive maintenance operation against the instrumentation nozzles is performed by the variety of device heads.
