摘　　要：通过改进FRAPCON-2程序中的燃料导热系数模型和裂变气体释放模型,使之能对高燃耗的燃料进行性能分析计算。并利用Halden堆IFA 597.3ROD8的试验数据对程序进行了验证。结果表明,改进后的程序所计算出的参数(如燃料温度和裂变气体释放份额)均与实测值符合很好,对程序的改进是成功的。The models such as thermal conductivity and fission gas release in FRAPCON-2 were improved for high burnup fuel analysis.Fuel irradiation data of IFA 597.3 ROD8 were used to validate the program.The result shows that some calculation values such as fractional fission gas release and fuel temperature are in good agreement with the measured values.So the improvement of FRAPCON-2 code is successful.
