JADA (Japanese Domestic Agency) who has the responsibility of ITER TF coil structure procurement had a contract for EU TFCS with HHI (Hyundai Heavy Industry). TFCS manufacturing is divided into 4 serial phases from preparation of call-for-tendering, basic design and development to procurement for actual product based on final design. To check the weldability and the tendency of weld deformation, the fabrication of 1-m mock-up have been performed. And the full scale trial reflecting the results of 1-m mock-up is being conducted to simulate the expecting behavior of final product during welding. Regarding the actual product of TFCS, the manufacturing design is on the final stage and the material procurements for fabrication are progressing now. This paper also presents future plan with schedule of EU TFCS manufacturing.
