Progress of ITER TF Coil Fabrication in Japan

QST, as Japan Domestic Agency in ITER, has responsibility to procure 9 ITER Toroidal Field (TF) coils and all 19 TF Coil Cases (CC). The 9 TF coils are procured by two suppliers to accelerate their production. The series production of Double-Pancakes (DPs) and Winding Pack (WP) are in progress in both two manufacturing lines. 55 DP windings, 40 DP impregnation and curing, 3 WPs and 8 CCs have been completed. Series production of TF coil WP and CC are progressing in Japan. Assembly of WP and CC is proceeding and gap-filling was completed in the first TF coil. Since the remaining process in the first TF coil is only final machining, we can say that the procedure of ITER TF coil fabrication have been well developed and established.
