Recent status of fabrication technology development of water cooled ceramic breeder test blanket module in Japan

As the primary candidate of ITER test blanket module (TBM) of Japan, development of water cooled ceramic breeder (WCCB) TBM is being performed. For installation of the TBMs in ITER, it is required to certify the quality of the TBMs. To certify the quality, it is necessary to show verifications of fabrication technique, fabrication capability and the integrity of prototypical size mockup in corresponding operation condition before the delivery of the TBM to ITER. This paper overviews the recent achievements of the fabrication technology development of the WCCB TBM in Japan. (C) 2011 Elsevier B.V. All rights reserved.
