摘　　要：在聚变-裂变混合能源堆球模型基础上,使用蒙特卡罗方法中子学程序对中子源、铀水体积比、产氚区等相关参数进行了中子学的敏感性计算。分析了各参数对混合能源堆能量放大倍数M和氚增殖比TBR的影响,并总结其基本规律,为开展进一步的混合能源堆概念设计提供了重要参考。The sensitivity analysis on neutronics parameters related to neutron source, uranium-water ratio and tritium breeding layers for spherical blanket model of fusion- fission hybrid reactor were presented. By using a Monte-Carlo method based neutron transport code, the effects of the parameters on energy multiplication factor M and tritium breeding ratio TBR were analyzed, and the general various laws of M and TBR were summarized, which were significant for the further conceptual design of fusion- fission hybrid energy reactor.
