Times Cited Count：19 Percentile：76.01(Nuclear Science & Technology)This paper presents recent results of ITER activities on Vacuum Vessel (VV), blanket, limiter, and divertor. Major results can be summarized as follows. (1) The VV design is being developed in more details considering manufacturing and assembly methods, and cost. Incorporating manufacturing studies being performed in cooperation with parties, the regular VV sector design has been nearly finalized. (2) The procurement allocation of blanket modules among 6 parties was fixed and the blanket module design has progressed in cooperation with parties. Fabrication of mock-ups for prequalification testing is under way and the tests will be performed in 2007-2008. (3) The divertor activities have progressed with the aim of launching the procurement according to the ITER project schedule.

The first wall of ITER blanket includes Be armor tiles joined to CuCrZr heat sink with stainless steel (SS) cooling tube and plate. Qualification tests of the FW fabrication technology are performed in order to qualify the joining technologies. The Japan Atomic Energy Agency has fabricated the qualification mock-up and carried out the materials tests and the non-destructive examinations. The results of tensile test showed that the Be/CuCrZr joint fractured at the interface because of large stress concentration. For the SS/CuCrZr joint, however, the joint fractured at CuCrZr apart from the interface. There was insignificant stress concentration at the interface edges. Since Charpy impact strength of the SS/CuCrZr joint was inferior to the CuCrZr, finite element analyses were carried out. Those fracture behavior were caused from the plastic deformation properties of both materials.
