Results of All ITER TF Full-Size Joint Sample Tests in Japan

Nine toroidal field (TF) coils have been developed in Japan for the international thermonuclear experimental reactor (ITER). The joint resistance of TF coil should satisfy requirement smaller than 3 nano-ohm at 2 T external magnetic and 68 kA transport current. Full-size sample (FSJS) tests were performed development manufacture, as part process control. 11 FSJS are conducted total. with assistance from a test faculty National Institute Fusion Science reported previous paper. All successfully satisfied less nΩ T. Additionally, joints subjected to cyclic electromagnetic force warm-up/cool-down during ITER operation. authors investigated performance abovementioned influence. results showed no degradation resistance. Thus, was qualified successfully.
