基于中国氦冷固态增殖剂试验包层模块(CN HCCB TBM)的最新设计方案和ITER提供的中子学基准模型C-lite,采用国际通用的Monte Carlo粒子输运程序MCNP和欧洲活化程序FISPACT-2007对HCCB TBM及其辅助系统(统称为HCCB TBS)进行了详细的活化计算分析,得到并讨论了各结构部件的放射性、余热和接触剂量率结果。结果表明,停堆时HCCB TBM模块的总放射性和总余热分别为2.348×1016 Bq和5.826 k W。活化计算结果可以为TBS的安全分析、维护和放射性废物处置等提供数据基础和分析依据。
Based on the latest design scheme of CNHCCB TBM and the C-lite standard model of neutron reference provided by ITER, the global Monte Carlo particle transport program MCNP and the European activation program FISPACT- 2007 carried out a detailed activation analysis of HCCB TBM and its auxiliary system (collectively referred to as HCCB TBS), obtained and discussed the radioactive, residual heat and contact dose rate results of various structural components. The results show that the total radioactivity and total residual heat of HCCB TBM module at shutdown are respectively 2.348 × 1016 Bq and 5.826 kW. Activation calculation results provide the data foundation and analysis basis for the safety analysis, maintenance and radioactive waste disposal of TBS.
