CSC implementation planSeptember <strong>2009</strong>) for preliminary discussions toprepare the collaborative work that will start in 2011.The DEMO R&D activities have progressed accordingto the schedule established in the Project Plan. Onthe breeding blanket, a pebble bed type blanket isconsidered as one of the most promising blanketconcepts both in the EU and Japan. Consideringthe demanding requirements on this component inDEMO, the timely development of blanket structuralmaterials and breeding/multiplying materials isessential. In this frame, a number of R&D Tasks havebeen proposed to be implemented through the BADEMO R&D program: T1: SiCf/SiC Composites, T2:Tritium Technology, T3: Materials Engineering forDEMO Blanket (reduced activation ferritic/martensitic(RAFM) steels as structural material), T4: AdvancedNeutron Multiplier for DEMO Blanket and T5:Advanced Tritium Breeders for DEMO Blanket.The EU participates in all tasks except T2. Twoworkshops (Kyoto, February <strong>2009</strong> and Barcelona,October <strong>2009</strong>) have taken place to evaluate theobtained data and to discuss future plans. The mainachievements in the EU tasks in <strong>2009</strong> are:On T1, ENEA is developing a multiscale methodologyfor composite structural modelling and validationof modelling procedure by mechanical testing: aprogressive failure method has been implementedinto a general purpose finite element program,ABAQUS, which allows the user to define materialConclusion of QPC PAproperties at a material point scale. ENEA also iscompleting a programme of determination of thethermal conductivity of SiC/SiC. CIEMAT is carryingout work to characterise basic properties of siliconcarbide materials (SiC and SiCf/SiC). Studies includevolume and surface electrical conductivity, H diffusion,and the effects of H and He on microstructure andelectrical conductivity.On T3, reduced activation ferritic/martensiticsteels RAFMs are considered the main candidatematerials for structural applications in DEMO. In<strong>2009</strong>, KIT has continued the characterisation of theproduction and treatment of EUROFER 97-3 plates.The irradiation effects on the mechanical propertiesand microstructure are studied in CRPP usingsmall specimen test techniques.
