摘要
用三维蒙特卡罗中子-光子输运程序MCNP和放射性计算程序FDKR,对中国ITER氦冷固态试验包层模块(CH HCSB TBM)进行了初步的三维活化分析。计算结果表明:TBM设计中活化产物的放射性、余热和潜在生物危害因子(BHP)主要来自结构材料;在500MW聚变功率下辐照0.53年,停堆时CH HCSB TBM的总放射性、余热和BHP分别为1.182×1017Bq、2.463×10-2MW和5.651×103km3.kW-1。在计算时,通过自动接口程序,实现了MCNP与FDKR之间的自动连接及数据处理。
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 500MW fusion power, the total radioactivity inventory, decay heat and BHP are 1.182× 10^17Bq, 2.463× 10^-2MW and 5.65 1× 10^3km^3·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.
