摘　　要：介绍了利用裂变堆提供的高强度热中子及裂变快中子,并采用LiD及铀作为转换靶,将反应堆内中子场局部转换为聚变-裂变混合中子场的物理设计结果,通过MCNP程序对转换靶结构及中子能谱调节材料进行优化设计,初步设计了转换靶的结构,并对转换靶内形成的聚变-裂变混合中子能谱以及转换靶的发热率进行了计算。In this paper,the physical designs about Fission-fusion mixed neutron field were introduced.The local mixed neutron fields which use the LiD and uranium target as the converter material were converted from the high-intensity reactor thermal and fission fast neutron fields.The structure of the conversion target and the material of neutron spectrum adjustment were optimal designed through the MCNP code.The structure of the converter target,the neutron spectrum of the Fission-fusion mixed neutron field and the heating rate distribution were obtained.

关 键 词：聚变-裂变混合中子场 转换靶 MCNP程序
