ABSTRACT:
The tool serves to brush the upper and lower counterbores and the channels which interconnect the counterbores in the lower flange of the lower guide tube of a nuclear reactor. The top entrance to the counterbores is partially obstructed by the wall of the guide tube which extends above the flange. The tool includes an upper brush and a lower brush mounted with their axes displaced laterally in opposite directions with reference to the common axis of the counterbores. The mounting is movable linearly and is pivotal about a horizontal axis and includes cam slots engaged by cam followers. When the mounting is moved in one direction (down typically) the upper brush is moved by the cam action into cleaning relationship with the upper counterbore. When the mounting is moved in the opposite direction (up), the lower brush is moved by the cam action into cleaning relationship with the lower counterbore and with the channel between counterbores.
