摘　　要：根据中国ITER实验包层模块CH HCSB TBM设计结构建立了TBM径向一维模型。运用燃耗计算程序BISON、聚变堆放射性计算程序FDKR和衰变链数据库AFDC-DLIB,计算了TBM设计中不同停堆时间活化产物的放射性、余热沉积、潜在生物危害因子BHP和辐射剂量,并根据计算结果初步得出相应的变化规律。计算结果表明,对于HCSB TBM来说,在500MW聚变功率下运行一年,停堆时的总放射性、余热、BHP分别为4.587×1015Bq,9.009×10-3MW和90.73km3·kW-1,后板处辐射剂量3.278×105 mSv·h-1。结果表明,CH HCSB TBM不存在突出的放射性环境安全问题。An analysis model has been constructed according to the geometrical arrangement and the material composition of CH HCSB TBM. The codes of BISON, FDKR and the decay chain data library AF-DCDLIB are used to calculate the radioactivity, afterheat decay, BHP （biological hazard potential） and the dose rate from activation products of HCSB TBM. The calculation results show that after a continuous operation over 1 years with 500MW fusion power the total radioactivity, heat decay and BHP are 4.587× 10^15Bq, 9.009×10^-3MW and 90.73 km^3·kW^-1 respectively, and the dose rate on the back plate is 3.278 × 10^5mSv·h^-1. It means that there is no serious environmental safety issue during the TBM operation.
