Abstract
Mechanical attachment apparatus is disclosed whereby antivibration bars are attached to a retaining ring at the location of the bent or curbed portion of the flow tube bundle of a stream generator adapted for use with a nuclear power plant. The mechanical attachment apparatus can be used with passive or expandable antivibration bars. A cylindrical member having a relatively long hook member attached thereto is connected to the ends of the antivibration bars. The hook member allows for wide variations in positioning when attaching the antivibration bars to a retaining ring located at and conforming to the periphery of the tube bundle. Latch apparatus secures the ring within the hook member. The attachment apparatus and the installation procedure are adapted to be performed under water using long-handled tools.
