摘　　要：使用中子学程序系统VisualBUS和活化数据库EAF-99对DFLL-TBM的高级子模块DLL-TBM 的活化特性进行了计算和分析,包括DLL-TBM各部件在不同停堆时间的活度、衰变余热和剂量率。活化计算所需要的三维中子能谱通过MCNP/4C中子/光子输运程序和国际原子能机构发布的FEND1．0 数据库计算得到。在活化计算分析的基础上,参照欧洲聚变堆安全和环境评估(SEAFP)策略中有关核废料的处理标准评估了TBM各区材料在退役后的废料处理工作,包括核废料应该采用何种适当的方式进行处理及其被完全清除干净的可行性。The neutron flux of the DFLL-TBM in ITER has been performed with the MC-NP/4C and the FENDL1.0 data library. Based on the neutron flux, the calculation and analysis on the activation levels of the different regions of DLL-TBM, including activi-ty, afterheat, and dose rate after shutdown, were carried out with the neutronics code system VisualBUS and the data library EAF-99. The safety and environment assessment of fusion power （SEAFP） strategy,which was developed in Europe, is applied to DLL-TBM for the management of activated materials. Accordingly, a recycling （re-use of the activated material） procedure is defined and the possibility for clearance （declassification of the material with low activity level to non-active waste） is investigated.
