Saturday Morning Session, CBBI-16 • Sound progress observed from CN, EU, JA, IN presentations both Design & R&Ds • CN • HCCB TBM design evolved specially from RAFM mass reduction point of view (2.6ton->1.3ton) • Materials development including structure, breeder, multiplier on going, preparing helium loop constructions (small loop with low temperature, 1.3kg/s loop with high temperature) • EU • HCPB TBM design evolved specially from Breeder Unit design point of view • Comprehensive R&Ds on-going (most of R&D items presented by the previous sessions) • JA • WCCB TBM design mostly maintained • Comprehensive R& on-going; TBM box structure fabrication on-going, advanced breeder(Li2+xTiO3+y) & beryllide (Be12Ti) development for later stage of TBM, continuous concept of tritium recovery R&D on-going • IN • LLCB TBM design evolution: 2 options • Materials development including structure, breeder, multiplier on-going, TBM fabrication technology started
Saturday Morning Session, CBBI-16 • Discussion & open issues • TBM vs. DEMO, how to extrapolate? • Different properties due to different conditions (irradiation properties, crush load, tritium release properties of pebbles, etc) • Different design (ex. Batch-wise tritium recovery vs. continuous recover) • How to resolve the gap between TBM & DEMO blankets • TBM C&S issue • No code for even non-irradiated RAFM • Validity /degree of conservatism when RAFM questionable • Collaboration possibilities to prepare IO requirement? • Diagnostics & instrumentations for TBM • What to measure: where to measure; how to measure • Development of instrumentations required? Considering harsh environment • Integration into design
