This paper overviews the design and development activities of Water Cooled Ceramic Breeder (WCCB) Blanket in Japan. Japan is performing the development of WCCB Blanket as the primary candidate of the breeding blanket for the fusion DEMO reactor. Regarding the design activity, structure design of blanket module and interfacing components and ancillary system have been performed. Regarding the development of blanket module fabrication technology, a real scale First Wall (FW) was fabricated using Reduced Activation Ferritic Martensitic Steel (RAFMS) F82H. Also, real scale Side Wall (SW) and real scale breeder pebble bed structure have been successfully fabricated. Furthermore, assembling of the real scale FW plate mockup and SW plate mockup was successfully performed. Development of major key technologies for the WCCB TBM structure fabrication has been almost completed.
