Current Status on the Fabrication Technology Development for ITER Blanket First Wall in Korea

Korea had responsibility for the procurement of the International Thermonuclear Experimental Reactor (ITER) blanket modules 1, 2 and 6 as a ITER participant. Now, our responsibility was changed from the procurement to only the development of fabrication technology including the international qualification. Each blanket module is composed of first wall (FW) panel and shield block. Especially for the FW, it is an important component which faces the plasma directly and it is subjected to high heat and neutron loads. The FW is composed of a beryllium(Be) layer as a plasma facing material, a copper alloy(CuCrZr) layer as a heat sink and type 316L authentic stainless steel(SS316L) as a structure material. For the joining of the above three metals, Hot Isostatic Pressing(HIP) has been developed including the Post HIP Heat Treatment(PHHT) in Korea. For the verification of the joining integrity, high heat flux(HHF) test for loading the cyclic heat load has been performed with foreign and domestic facilities. In the present paper, the development procedure and future plan was introduced
