为研究在大型商用压水堆中采用环形燃料元件的可能性，需分析环形燃料的堆芯物理性能。本文研究了CASMO5程序计算环形燃料组件物理参数出现偏差的原因及其处理方法，分析了4组环形燃料先导组件加入秦山二期核电站平衡循环堆芯之后的堆芯物理参数。计算结果表明，装载的环形燃料先导组件对堆芯物理性能影响较小，基于CM S程序包开展环形燃料堆芯物理性能分析计算是可行的。

The reactor core physical analysis of annular fuel is needed in order to investi‐gate feasibility of annular fuel applied in the large commercial PWR .The reasons behind inaccurate results when using CASMO5 code were studied and the methods to deal with the problems were introduced .And the steady state core physics performance was ana‐lyzed with four groups of annular fuel leading test assembly loaded into the steady state reactor core of Qinshan Phase Nuclear Power Plant Ⅱ . According to the computed results ,loading annular fuel leading test assembly has little influence on the steady state core physics performance , and it is feasible to do annular fuel reactor core physics performance calculation by CMS code package .
