The maintenance, replacement and decommissioning of future nuclear fusion reactors will require quick and reliable cutting and joining of in-vessel pipework. It is estimated that cutting and welding could account for up to 60% of the maintenance duration using conventional in-situ processing techniques. Additionally, the expected radioactivity and limited access at the cutting and welding sites mean these processes cannot be done manually and robotic tools are required. To this end, remote in-bore laser cutting and welding tools have been developed for use in 90 mm internal diameter steel pipes. The technology is readily transferable to many remote applications in challenging environments such as fission reactor maintenance, nuclear decommissioning and other in-accessible pipework
