Non-destructive examination with infrared thermography system for ITER divertor components

Seki, Yohji; Ezato, Koichiro; Suzuki, Satoshi; Yokoyama, Kenji; Enoeda, Mikio; Mori, Seiji

Japan Atomic Energy Agency (JAEA) is willing to procure the outer Vertical Targets (VT) in cooperation with ITER Organization. In advance of the start of the procurement, the JAEA has to first demonstrate its technical capability to carry out the procurement. This is achieved via the successful manufactures and quality tests of VT Qualification Prototypes. Non-Destructive Examination (NDE) with the infrared thermography is required as one of the quality tests to detect the defect in the CFC monoblock, and between the CFC/OFCu. In this research and development, the Facility of Infrared NDE for Divertor (FIND) has been built by the JAEA. The FIND successfully detects the position and the magnitude of the integrated defect in the CFC and in the bonding of CFC/OFCu. The infrared NDE system established in the JAEA contributes to keeping the quality of the ITER-divertor.
