As a part of the Broader Approach (BA) program, R&D on DEMO blanket related materials and tritium technology has been started in 2007 by both the EU and Japan. In accordance with the common interest of the EU and Japan, the followings subjects have been applied: reduced activation ferritic martensitic steels; silicon carbide composites: advanced tritium breeders and neutron multiplier; and tritium. These R&D studies are mainly carried out in Rokkasho site in Japan. Hence, we defined the period of 2007 to 2009 as Phase 1, and have carried out the design and fabrication of the equipment at Rokkasho. Activities for the licensing of the equipment for tritium and beryllium handling have also been carried out. The equipment is the first and quite unique facility in Japan, where tritium, and RI species, and beryllium can simultaneously be used. It has also the first challenge in Japan that researchers in various fields of blanket join R&D program at a facility.
