摘　　要：文章介绍秦山核电站考验元件辐照后燃料ＵＯ２的微观分析结果。用定量金相方法，结合晶粒长大动力学原理，计算出元件的中心温度，结果与ＦＲＡＰ－ＣＯＮ程序分析相符。以辐照后检验结果为基础，确定了评价国产燃料ＵＯ２辐照行为的参数Ｋ和Ｑ值。The micro-analysis results of UO2 fuel core of irradiated test elements designed for Qinshan Power Plant are presented in the report. The temperature of the element centers is quantitatively calculated by using the grain size measurement results according to the principle of grain growth dynamics, and the results are in accordance with that of the FRAP-CON calculation. Based on the post-irradiation examination data, the dynamic parameters, K and Q which are particularly suitable to description of irradiation behaviours of UO2 fuel made in China are deduced.
