摘　　要：本文提出了一种新的基于三维确定论方法的ITER实验包层模块中子学分析策略。该计算策略分为两步:第1步将包层模块离散,利用3D模块化MOC方法求解细群中子注量率;第2步在整个模块上利用简化球谐函数方法进行中子学计算。在此基础上编制程序,并对液态锂铅实验包层模块进行计算,给出了各区中子注量率、TBR等中子学参数,并与MCNP程序的计算结果进行比较,比较结果证明了计算方法及程序的正确性。A new strategy for the neutronics analysis of the ITER test blanket module based on 3D deterministic method was proposed.It was composed of two steps： Firstly,the module was dissected into individual parts and the 3D modular MOC method were implemented on them to calculate the fine group fluence rate;In the second step,SP3 method was adopted to obtain the fluence rate distribution throughout the whole module.The code based on this new strategy was developed and calculation on the dual-functional lithium lead test blanket module was finished.Main neutronics parameters including the fluence rate distribution and TBR were given and compared to those obtained from MCNP.The results verify the validity of the new strategy and the code.
