摘　　要：使用中子输运设计与安全评价软件系统(SuperMC)和聚变评价数据库JEFF3.2,根据中国聚变工程试验堆(CFETR)第一阶段设计要求,对双功能液态铅锂包层中各部件的活化特性进行计算和分析。采用燃耗输运耦合方法计算了聚变堆赤道面内、外包层中各部件放射性活度、衰变余热、剂量率和潜在生物危害随停堆冷却时间的变化,并根据欧洲聚变堆安全和环境评估策略中核废料处理标准,分析了聚变堆退役后氚增殖包层的废料处理问题。分析结果表明:在功率200 MW时正常运行10 a条件下,包层中各部件在经过50 a冷却后均可达到简单回收标准,满足CFETR第一阶段放射性废物处理要求。Based on the design requirements of the first stage of the China Fusion Engineering Test Reactor(CFETR),the activation performance calculation and analysis of the components in the dual function lead-lithium blanket were performed using a neutron transport design and safety evaluation software system(SuperMC)with the fusion evaluation database JEFF 3.2.A coupled burnup and transportation calculation method was used to calculate the radioactivity,residual decay heat,dose rate,and potential biological hazards of each component in the equatorial surface of the fusion reactor at different times after shutdown.The waste disposal problem of the tritium breeding blanket after the decommissioning of the fusion reactor was analyzed according to the relevant nuclear waste disposal standards in the safety and environment assessment of fusion power strategy.Results of the analysis show that under the condition of normal operation of 200 MW for 10 years,all components of the breeding blanket in the CFETR can satisfy simple recycling standards and meet the requirements of the first stage of CFETR radioactive waste treatment after 50 a of cooling.
