Development of the plasma facing components in Japan for ITER

After the successful completion of the prequalification activity for ITER divertor procurement, Japanese Domestic Agency (JADA) and ITER Organization (IO) have entered into the procurement arrangement of divertor Outer Vertical Target (OVT) in June 2009. In accordance with the arrangement, JADA is going to fully procure the outer target components which correspond to 60 divertor cassettes. JADA has started to manufacture an OVT full-scale prototype in order to pick out/solve technical and quality issues and to establish a rational manufacturing process toward the start of the series of production of the OVT components to be installed in ITER. This paper presents the overview of JADAʹs manufacturing activity and the procurement schedule on the divertor outer target procurement.
