As the primary candidate of ITER Test Blanket Module (TBM) for the first day of ITER operation, development of Water Cooled Solid Breeder (WCSB) TBM has been performed toward the TBM milestones, which are necessary for acceptance of the TBM in ITER for testing from the first day of plasma operation. Regarding the liquid breeder blanket development, universities and NIFS are conducting the development. This paper overviews the recent achievements of the TBMs and DEMO blankets.
