  • Patent number: 7797781
    Abstract: A robot mechanism adopts a dry cleaning method to clean the surface of live-line insulators without using water and can perform cleaning and inspection of the surface of the live-line insulators while automatically moving along an insulator string. The robot mechanism includes a main unit having upper and lower wing frames connected with each other by a connecting bracket to surround the insulator string, a cleaning unit disposed between the upper and lower wing frames and including a base frame to perform dry cleaning with a rotational brush and a CM guide, a lift unit including a clamp and a ball-bearing screw to move the main unit up or down, and an inspection unit to electrically inspect the insulators; and a coupling unit to couple a pair of the main units to allow the pair of main units to move along a tension insulator string or a suspension insulator string.

  • Publication number: 20090052605
    Abstract: A handling system for an in-core detector thimble tube of a reactor is disclosed. The handling system serves to withdraw and retract a thimble tube so as to provide a movement path of a movable detector used to measure a neutron flux within a reactor. For this, the handling system basically includes a thimble tube withdrawing/retracting device, which grips the thimble tube using a plurality of synthetic resin pinch rollers to withdraw and retract the thimble tube without any damage to the thimble tube, a thimble tube tensioning device, which applies a constant tensile force to the thimble tube to prevent the thimble tube from shaking or bending upon withdrawing/retracting operations, and a thimble tube platform, which temporarily keeps the withdrawn thimble tube at a fixed position without a risk of shaking of the thimble tube and provides a movement path of the thimble tube tensioning device.

  • Patent number: 7133488
    Abstract: A neutron flux mapping system for a nuclear reactor including: drivers each including a geared motor, a helical gear driven by the geared motor, and a storage reel adapted to supply, to the helical gear, a detector cable carrying a detector; and a double indexing path selector unit including upper and lower fixed plates, a fixed shaft, an outer path selector rotatably mounted to the upper fixed plate, and inner path selectors. The outer path selector includes an upper rotating plate rotatably mounted to the upper fixed plate while carrying a drive unit for rotating the outer path selector about the fixed shaft, and a control unit for controlling the drive unit, and a lower rotating plate connected to the upper rotating plate.
