| 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90.73 km3?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。

| Abstract: | 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 4.587×1015Bq, 9.009×10-3MW and 90.73 km3?kW-1 respectively, and the dose rate on the back plate is 3.278×105mSv?h-1. It means that there is no serious environmental safety issue during the TBM operation. |
