Advances in the manufacturing activities for the supply of 9 TF coils of JT-60SA Tokamak and associated validation program

The status of the manufacturing of 9 of the 18 Toroidal Field (TF) coils of the JT-60SA tokamak under ENEA responsibility is presented. The activity, carried out in the framework of the Broader Approach Agreement between Europe and Japan for the construction of the JT-60SA tokamak, has officially started on October 2011 after the kick-off meeting between ENEA and ASG superconductors in Genoa. The 9 coils are being manufactured under the supervision of ENEA in collaboration with the JT-60SA European home team by ASG superconductors. The remaining coils will be constructed by ENEA’s French counterpart CEA. Once completed, the coils will be delivered to CEA at Saclay to perform the cold tests before final shipping to Naka. The manufacturing consists of several steps and phases. The first phase regards the completion of the manufacturing drawing and components needed for the production. Therefore the first year of activity has been devoted to the issuing of the manufacturing drawings and procurement of the tools. Also, prior to the start of the manufacturing, a preparatory activity has been planned aimed at setting-up the most critical manufacturing process. At this aim, several qualification activities have been performed. In this report an overview of the principal milestones reached during the preparatory phase and a description of the qualification activities with relevant test results are presented. Also the activities implemented for the next year are described.
