Abstract
A thimble guide extender for use in a nuclear power plant shields the thimble from turbulence and absorbs vibration from it to reduce wear. The extender includes an extension element which is secured to the thimble guide, a spring bushing which is attached to the extension element and which contacts the thimble, and a cap. In one embodiment the cap clamps the spring bushing, and in other embodiments it simply shields the bushing from turbulence. In one embodiment the spring bushing is an element having a cylindrical portion on one side and dimpled spring legs on the other, in another embodiment the spring bushing is an element having bent spring legs on either side, and in another embodiment the spring bushing is provided by dimpled spring legs that are integral with the extension element. The extension element is provided with locking fingers which secure the extension element to the thimble guide.
