摘要:

基于中国氦冷固态实验包层模块(CH-HCSB-TBM)的新设计方案,采用蒙特卡罗粒子输运程序MCNP和欧洲活化计算程序FISPACT,对CH-HCSB-TBM进行了三维活化计算分析。计算结果表明,停堆初期TBM总的放射性活度、衰变余热分别为1.78×1016Bq和3.01kW,主要受结构材料CLF-1影响。同时给出了影响TBM材料活化特性的主要核素及其生成途径,为TBM设计的材料选取和优化提供依据。根据计算的停堆剂量率可知,TBM中的活化材料都能采取远程操作实现再循环利用,可有效防止放射性环境危害问题

Abstract:

Based on the new design of China 2×6 helium cooled solid breeder (CH-HCSB) test blanket module (TBM), three-dimensional activation calculation analysis was performed by using the Monte Carlo particle transport code MCNP and European activation code FISPACT. The results show that, at the beginning moment after shutdown, the total activity is 1.78×1016Bq, and the total afterheat is 3.01kW. They are both dominated by the structural material CLF-1. Meanwhile, the dominant radioactivity nuclides and reaction pathways have been identified. The results will provide useful indications for materials selection and further optimization design of the TBM. On basis of the calculated contact dose rate, the activated materials can be reused with the remote handling recycling options. That is effective for preventing from the radiation environmental hazard.
