A remote repair was required to secure the ‘Split Tubes’ in the Oldbury reactors. The hardware to carry out the repair had to be developed for use in reactor in a relatively short timescale. New innovative design solutions were required and this paper outlines some of the work packages designed, built and tested by Remote Operations (BNFL Magnox) for the Oldbury thermocouple retention project. Work packages included Scanning, Surface Preparation, Welding and Camera packages, the details of which are described in this paper.
