摘要： An apparatus is provided for use with a pressurized-water reactor's steam generator having a manifold chamber enclosing the bottom side of a horizontal tube sheet having holes therethrough in which are mounted the tubes of a heat exchanger tube bundle, the manifold chamber having a manhole giving access to the tube's bottom side to permit internal inspection or repair of the tubes by registration of an end of a flexible guide conduit with the tube sheet holes and through which a flexible carrier can be guided for insertion via these holes in the tube sheet and through the tubes extending from the tube sheet's other side. The apparatus is a light-weight fixture which is manually insertable through the manhole and comprising a beam, means for detachably supporting the beam horizontally in the chamber beneath the tube sheet's bottom side, a horizontal cantilever arm having one end provided with means for supporting the aforementioned guide conduit with its end pointing upwardly and means for mounting the other end of the arm on the beam for horizontal movement of its end having the guide conduit supporting means. The carrier is a flexible hose insertable through any one of the heat exchanger tubes, and being tubular, the carrier hose can carry conductors from an inspection or repair device mounted on the inner end of the carrier hose, back to the relatively safe, remote location for measuring or controlling purposes. The apparatus has additional features.
