Abstract
QST, as Japan Domestic Agency in ITER, has responsibility to procure nine ITER toroidal field (TF) coils and all 19 TF coil cases (CC). The nine 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 manufacturing lines. In total, 45 DP windings, 30 DP impregnation and curing, and the first WP cold test and the second WP impregnation have been completed. In addition, four CCs have been completed. Assembly of the WP and CC of the first TF coil will start from the beginning of 2019. To qualify the assembly of the WP and CC, trials including those to estimate closure welding deformation and qualification of tooling have been performed. The assembly procedure has been developed based on these results.
