Description
ENEA, in the framework of Broader Approach program for the early realization of fusion with the construction of JT-60SA tokamak, has committed to procure 9 of the 18 TF coils of JT-60SA magnet system. Within 2016 six coils will be completed and delivered to the cold test facility in Saclay, France, for the final acceptance tests before their shipment to Naka site for the assembly.
Manufacturing has been divided in two main production steps: winding pack (WP) manufacturing and integration into casing. All the nine WPs have been already completed on September 2015 and the final integration phase has started in 2015 for the first coil. The integration, in its turn, is composed of six sub-steps: insertion, welding, embedding impregnation, final machining of interface areas, He piping assembly and final acceptance tests. Each of these steps has been already accomplished and the first coils have been delivered to Saclay to undergo the cryogenic acceptance tests.
This paper provides an overview and intermediate assessment of the contract that ENEA signed with ASG Superconductors for this supply. Main electrical, geometrical and fluidic results of the nine WP produced and of the TFCs completed so far are also reported.
