As the primary candidate of ITER Test Blanket Module (TBM) to be tested under the leadership of Japan, Water Cooled Solid Breeder (WCSB) TBM is being developed. This paper shows the recent achievements toward the milestones of ITER TBMs prior to the installation. Structure designs of the WCSB TBM and the interfacing components that are placed in a test port of ITER and layout of cooling system are presented, targeting the detailed design final report in 2012. As for the module qualification, a real scale first wall mock-up fabricated by using Hot Isostatic Pressing (HIP) method by structural material of reduced activation martensitic ferritic steel, F82H, and flow and irradiation test of the mockup are presented. As for safety milestones, contents of the preliminary safety report in 2008 consists of source term identification, Failure Mode and Effect Analysis (FMEA) and identification of Postulated Initiating Events (PIEs), and safety analyses, are presented.
