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 paper introduces the microscopic analysis results of fuel UO2 irradiated by Qinshan Nuclear Power Station test components. Using the method of quantitative metallography and the principle of grain growth kinetics, the center temperature of the component was calculated. The result was consistent with FRAP-CON program analysis. Based on the test results after irradiation, the parameters K and Q for evaluating the irradiation behavior of domestic fuel UO2 were determined.
