Abstract
A steam generator for use with a nuclear power plant is provided with expandable antivibration bars. The antivibration bars are positioned between columns of tubes in the steam generator and are attached to retaining rings surrounding the bundle of tubes. The antivibration bars are provided with upper and lower bars having mating surfaces comprising series connected inclined planes which allow for relative motion between the upper and lower bars and provide a means to increase the overall thickness across the two bars. Take-up means are provided to guide and assure proper relative motion. The antivibration bars are divided into two elongated lengths each of which forms one of the legs of the 'U' shape which the antivibration bar assumes at installation. A double pivot is provided at the connection between the two legs to allow side-by-side positioning of the legs which facilitates installation into an already built steam generator.
