摘　　要：秦山CANDU重水堆物理跟踪计算使用的基本栅元计算,使用的是PPV程序计算产生的1.5群栅元截面,随着对计算精度越来越高的要求,以及将来新燃料类型的使用,有必要更新为WIMSAECL程序计算产生的2群栅元截面。本文重点研究基本栅元计算程序从PPV到WIMS-AECL的转换,以及基于转换后的程序,堆芯跟踪计算程序系统的更新方法,并对转换前后的计算结果进行了对比分析。The basic lattice calculation used in Qinshan CANDU reactor physics core tracking,currently use 1.5 group lattice sections which is calculated by PPV code. With the requirement of increasing calculation precision and the use of new fuel type in the future,it is necessary update to use 2 group lattice sections which is calculated by WIMS-AECL code. This paper focuses on the basic lattice code transition from PPV to WIMS-AECL,and the updating method of core tracking program system based on the transition code. The calculation results were compared and analyzed before and after transition.
