Abstract
Considering to reduce the filling factor of Be pebble bed from 80% to 62% in preliminary design phase, preliminary neutronics design and optimization for conceptual design of China ITER helium cooled ceramic breeder test blanket module (HCCB TBM) have been performed and the optimized HCCB TBM design has been proposed with modifying the material and arrangement of TBM inner components. This design has a better neutronics performance and satisfies the safety demand. Calculation results show that the tritium production rate of optimized HCCB TBM design is increased by 0.42mg/FPD comparing with conceptual design, but the total nuclear heating and peak power density are lower than conceptual design. These results can be used as supporting analyses for HCSB TBM preliminary design.
