In-Core Guide Tube Repairs
Main description
The control rod guide tube is a safety component which ensures timely control rod drop. Wear may occur on the guide plates, in which case guide tube replacement is required. Framatome offers solutions for guide tube removal and replacement. Our customers can choose to replace a guide tube either with a new tube or with a refurbished tube. Two guide tubes can also be switched. The work is performed underwater during a normal outage while the upper internals are on their stand. The operators work from the refuel bridge or an auxiliary platform.
