JT-60SA TF Magnets Industrial Production Status at Alstom

Abstract

The general design of the JT-60SA TF system was defined by all the participants in the project (CEA, ENEA, F4E); the detailed design was issued by the voluntary contributors. For the French part, including the procurement of 9 of the 18 TF winding packs and their integration in the casings, an industrial contract was signed with Alstom (France). After the first phases, including manufacturing flow definition, manufacturing drawings and QA documentation, critical processes qualification, as well as procurement and commissioning of the tooling, the production was started in January 2014. After solving the setting issues linked to industrialization of complex tooling such as the winding machine or impregnation mold, the winding operations, as well as the joint area manufacture and the impregnations, were led. The first winding pack insertion process, as well as casing welding using an industrial robot, was performed during the year 2015 with the target to deliver the first coil to the cold test facility before the end of the year. Of course, in parallel, the successive coils manufacturing was engaged. This paper presents the status of the production with a focus on the issues encountered on the first coil and the production objectives.
