Activation and afterheat analysis for CH HCSB TBM

With an activation calculation code FDKR and decay chain data library AF-DCDLIB, the radioactivity,afterheat decay and Biological Hazard Potential (BHP) from activation products have been analyzed in the CH HCSB TBM. The calculation results show that the total radioactivity inventory, heat decay and BHP are 2.10×1016Bq、5.06×10-3 MW、68.6 km3·(Kw)-1,respectively, at shutdown after a continuous irradiation over 0.53 years with 500 MW fusion power.It shows that there isn't seriously environmental safety issue in the TBM.
