Abstract
The fuel rods located in areas of a nuclear reactor core where water jetting damage to the rods can occur are secured together by a clip, in order to change the mass subject to fretting damage. The change of mass changes the amplitude of the induced fuel rod vibration, thus reducing possible fuel rod fretting and/or damage. To repair such damage, the combination of clip(s) and an inert rod are used to replace a damaged fuel rod.
