1 Description of structure, materials and MCNP model Except that height, sub-module numbers of present HCSB TBM increases by 2 times, there are hardly other changes in structure and geometry. Fig.l shows general schematic for 3-D structure of previous 3 X 3 and updated 3 X 6 HCSB TBM structure. Present 3X6 HCSB TBM box is mounted on 1/2 ITER testing port. It is 48.4 cm in width, 66 cm in height, 63 cm in depth, 2 cm of gaps on side faces between frame wall and TBM box. A frame wall thickness around TBM module is 20 cm.
