ABSTRACT:
A track and carriage combination for supporting maintenance equipment in pressurized water reactor steam generators is disclosed. A pair of outwardly extending grooves are machined into the annulus portion of the generator tubesheet. Geared segments are provided for being inserted in the grooves for forming a geared track upon which the maintenance device may be firmly supported. Each geared segment includes gear teeth, a base shaped to mate with and engage the annulus grooves. A keyway is provided at the tubelane for allowing the segments to be slidably inserted into the grooves. Each segment is slightly curved so as to form a track corresponding with the annulus curvature. The segments are interlockable so that the segments may be removed from the annulus without any segments being left inside the steam generator. If desired, the track may be of one-piece construction and permanently mounted in the annulus. Each segment includes shoulders for supporting and stabilizing the maintenance device in conjunction with support arms on the maintenance device. The track of the present invention is preferably for use with a support carriage mounted to the maintenance device. The support carriage is of suitable design for use with the track cross-section, having gears corresponding with the gear teeth on the track and support arms for grasping the track shoulders.
