Three-dimensional activation analysis for ITER solid test blanket module

Using the codes of MCNP and FDKR, the activation analysis for CH HCSB TBM (China Helium-Cooled Solider Breeder Test Blanket Module) has been performed. The calculation results show that after a continuous irradiation over 0.53 years with 500 MW fusion power, the total radioactivity inventory, decay heat and BHP are 1.182 x 1017 Bq, 2,463 x 10-2 MW and 5.651 x 103 km3·kW-1, respectively, which are attributed mainly to the structure materials. In order to realize the automated routing of the neutron flux spectra from MCNP to FDKR, the two codes are linked through the automated interface code. (authors)
