Two double pancake coils of ITER TF coil are electrically connected at the joint. To evaluate the ITER TF joint performance, the joint test sample, which consists of two TF conductors and has full size joint part, was fabricated. The joint sample was tested using NIFS test facility under the condition of current of 68kA and external field of 2T. As a result, the joint resistance could be 1nohm, which is sufficiently small. In this presentation, detail of the test result is reported.

JAEA has to responsibly procure nine Toroidal Field (TF) coils as Japanese domestic agency. To manufacture the TF coil, full-scale trials (manufacturing of dummy DPs) is carrying out as a qualification of the manufacturing process. From October in 2013, the manufacturing of the first TF coil was started. In this presentation, results of full-scale trials and progress of the TF coil manufacturing are reported.

JAEA has responsibility of procurement of 9 ITER Toroidal Field (TF) coils in ITER. Prior to TF coil fabrication, JAEA started to fabricate three dummy double pancakes (DPs) in order to confirm the commissioning of the facilities for DP fabrication and establish the manufacturing process of the DP. Fabrication of the dummy DP as full-scale trials has been started from October, 2013. In this full-scale trial, the control of conductor length with $$pm$$0.01%, flatness of radial plate (RP) with $$pm$$2 mm and flatness of DP after CP welding with $$pm$$2 mm were achieved and conductor elongation due to heat treatment was evaluated. Based on these results, TF coil winding has been started. The conductor winding has been already completed for 11 DPs of the TF coil and 10 DPs were heat treated. The conductor elongation is within expected value of $$pm$$0.02%.
