Progress of ITER and JT-60SA Magnet Development in Japan

Japan Atomic Energy Agency (JAEA), as the Japan Domestic Agency (JADA), has the responsibility to procure 9 ITER toroidal field (TF) coils, 19 TF coil (TFC) structures, 25% of the TF conductors and 100% of the central solenoid (CS) conductors in ITER and, in addition, CS and equilibrium field (EF) coils including their conductors in JT-60SA, which is being developed as a satellite facility for ITER. In ITER, more than 90% of TF conductor fabrication was completed and finalization of the manufacturing procedure of TF coils is in progress through full-scale trials, such as trial fabrication of dummy double pancakes (DPs). In JT-60SA, fabrication of the EF4 coil was completed and the EF5 and EF6 coils are being assembled.
