Title: Fuel handling apparatus for a nuclear reactor

Abstract

This patent describes a fuel handling apparatus for operation through an opening in the side of a reactor vessel having a plurality of fuel elements disposed in an array within the vessel, the apparatus comprising: a support housing for affixation to an exterior portion of the vessel, the housing enclosing an interior space having a generally horizontal longitudinal axis; a support member mounted for motion longitudinally of the housing within the housing; a first arm supported by the support member and pivotal about a vertical axis through the support member; a second arm supported by the first arm and pivotal about a horizontal axis through the first arm; means for pivoting the first and second arms about their respective axes; reversible extendable lifting means fixedly supported by the second arm for positively moving the fuel elements upward and downward. The lifting means includes a storable tubular extendable member comprising at least one ribbon which may be compactly stored on a reel and which may be extended into an elongated, relatively rigid configuration; grapple means supported by the lifting means for releasably connected the lifting means to the fuel elements; and lateral transport means for moving the support member longitudinally ofmore » the housing.« less
