ITER TF conductors will be procured by 6 parties, which are Japan, EU, Korea, Russia, US and China. Japan will procure 25% (4.75 coils) of the TF conductors. 100 tons of NbSn strands will be procured by JA for the TF conductors and total length of the conductor shall be 22 km. ITER organization and JAEA have signed agreement to procure the TF conductor last November. JAEA separated the procurement into three categories, which are strand, cable and conductor procurements. Before the procurement, JAEA has evaluated performance of 4 kinds of full size conductors, each of which uses NbSn strands fabricated by respective Japanese company. Test results of 2 kinds of conductors were presented last year. This time, test results of other conductors will be presented.
