    摘要： A system, method and apparatus for remotely installing a flange cover assembly on a fuel transfer tube fixed flange in a containment pit in a nuclear power plant is presented. In one example, the flange cover assembly includes J-bolt spring assemblies in which the feet of the J-bolt are rotated between a clamping and non-clamping orientation to engage with the rear face of the fixed flange. A tool frame is lowered into the containment pit to engage with the flange cover assembly to compress the J-bolt springs and extend the J-bolt foot toward and away from the flange cover. Dual acting cylinders move a spring compression frame on the frame tool to compress and relax the J-bolt spring assemblies.

    摘要： A device is provided for repairing a damaged location in an underwater region of a wall of a vessel or pool, in particular in the region of a wall of a pool of a nuclear reactor plant. The device includes a guiding system, which can be attached along a side wall at a distance therefrom and can be fixed thereto, for guiding a carriage which can be made to move in a longitudinal direction of the guiding system. Arranged on the carriage is a displaceably mounted holder for a repair support, which can be placed with an adhesive surface against the wall region containing the damaged location. With such a device, wall regions that are at a great depth and can only be accessed through narrow gaps can be repaired quickly and reliably.

    摘要： According to an embodiment, a horizontally moving stage is mounted on a cylindrical structure within a reactor pressure vessel, travels horizontally along the surface of the cylindrical structure by wheels, and is positioned above an in-reactor pipe by the operation of the horizontally moving stage. A hollow mast is carried by the horizontally moving stage, and is expandable and contractible in a vertical attitude. When the mast is in the vertical attitude, a probe is movable within the mast and performs work in the proximity to the inner surface of the in-reactor pipe. A cable passes through the mast to be connected to the probe.
