A rigging system for reactor closure head and reactor internals lifts. The system includes a plurality of latchbox pendants attached to the lifting structure of an overhead crane. A first set of a plurality of lifting lugs is attached to the reactor internals, each of the lifting lugs corresponding to one of the plurality of latchboxes. A second set of a plurality of substantially identical lifting lugs, each of the lifting lugs corresponding to one of the plurality of latchboxes, is attached to a plurality of solid rod lifting pendants attached at one end to the reactor closure head. In operation, the latchbox pendants may be rigged once to the overhead crane for handling reactor internals and left in place throughout the entire rigging sequence without changing to turnbuckle pendants for reactor closure head handling.

Reactor head lift apparatus

A tool fixture device for positioning tools to repair defects adjacent to the sealing grooves in a pressure vessel head. The device includes a two pair of parallel, spaced apart, arcuate segments adapted to fit into one of the sealing grooves. A support plate is attached to the first and the second pair of parallel, spaced apart, arcuate segments. The fixture includes a plurality of threaded rods for expanding the ends of the parallel arcuate segments to engage the inside walls of one of the grooves to hold the fixture in place. In the preferred embodiment, a tool positioner is adapted to be attached to the support plate for positioning a repair tool to permit the repair tool to be used to repair defects adjacent to the sealing grooves. The tool positioner includes a planar table and a tool jig attached to the planar table for receiving the repair tool.
