Under the Agreement Between the Government of Japan and the EURATOM for the Joint Implementation of the Broader Approach Activities (BA Activities) in the Field of Fusion Energy Research, JAEA develop a new site at Rokkasho-mura in Aomori prefecture of Japan as the Japanese Implementing Agency. In this new site, two of the three projects of the BA Activities are to be implemented, namely, International Fusion Energy Research Center (IFERC) Project and International Fusion Material Irradiation Facility/Engineering Validation and Engineering Design Activity (IFMIF/EVEDA) Project. In March 2009, the Administration and Research Building was completed, and the other research facilities; CSC&REC Building, DEMO R&D Building and IFMIF/EVEDA Accelerator Building will be completed in March 2010. In this presentation, the specifications and construction schedule of the individual research buildings will be presented, especially special features of the IFMIF/EVEDA Accelerator Building.

Times Cited Count：20 Percentile：78.32(Chemistry, Physical)Radiation-induced graft polymerization of vinyl acetate (VAc) onto poly(3-hydroxybutyrate) (PHB) film was carried out. At a degree of grafting higher than 5%, the grafted films (PHB-g-VAc) completely lost the enzymatic degradability that is characteristic of PHB due to the grafted VAc covering the surface of the PHB film. However, the biodegradability of the PHB-g-VAc films was recovered when the films were saponified in alkali solution under optimum conditions. Graft chains of the PHB-g-VAc film reacted selectively to become biodegradable polyvinyl alcohol (PVA). The biodegradability of the saponified PHB-g-VAc film increased rapidly with time.

Times Cited Count：21 Percentile：53.63(Polymer Science)Radiation-induced graft polymerization of acrylic acid (AAc) on the surface of poly(3-hydroxybutyric acid) (PHB) film was carried out by applying pre-irradiation techniques. The PHB films grafted with AAc (PHB-g-AAc) possessed a degree of grafting higher than 5% have completely lost the enzymatic degradability. The enzymatic degradability of the grafted film was recovered by remolding. And the highest enzymatic degradation rate was observed to grafted films with AAc 10% of degree. Difference of enzymatic degradability of PHB-g-AAc film was caused by decrement of amount of enzyme contact and decrement of crystallinity of PHB by remolding.

Carboxymethylcellulose gel (CMC gel) was produced by irradiation of 
rays for CMC. The CMC gel is expected to be applied in biomedical and agricultural uses so that it has high water absorbability. The objectives of this study are to isolate and to identfy CMC gel degrading microorganism, and reveal its decomposition mechanism in detail. We isolated and identfied CMC gel-degrading microorganisms from soil. The isolates belonged to Gram-positive bacterium group, hydrolyzed CMC, and CMCgel to low molecular substances.

For Broader Approach Activities, which are joint project between Japan and Europe, JAEA who is the Japanese implementing Agency, has established "International Fusion Energy Research Centre (IFERC)" in Rokkasho, Aomori Japan. At research facilities in IFERC, DEMO R&D Building and CSC&REC Building, in which research and development activities are carried out, experimental equipment and components had been installed and in operation until the end of 2011. The outline of those facilities are described in a poster.
