摘　　要：为了评估参数不确定度给燃料元件性能带来的影响,需要对设计阶段的燃料元件误差范围内参数组合进行计算和评估。采用正交实验方法对棒状燃料元件关键参数进行组合取值并编制测试算例,以评估参数不确定度对燃料元件行为的影响。根据选取的关键设计参数和各参数水平编制混合水平正交表,并确定36组测试算例。对36个算例进行测试计算,结果表明部分测试算例的包壳总变形不满足燃料棒设计准则,说明参数不确定度对燃料元件行为产生了负面影响。测试算例的编制和分析对燃料元件设计具有一定的指导意义。In order to assess the impact brought about by parameter uncertainty on fuel elements performance,combinations of parameters within the error range of the fuel elements at the design stage need to be calculated and evaluated.Orthogonal experimental methods were used to take values for combinations of key parameters of the rod fuel elements and to prepare test cases.Mixed-level orthogonal tables were prepared based on the selected key design parameters and the levels of each parameter,and 36 sets of test cases were identified.Test calculations were performed on the 36 cases,and the results showed that the total cladding deformation of some test cases did not satisfy the fuel rod design guidelines,indicating that the parameter uncertainty negatively affected the fuel element behavior.The preparation and analysis of the test cases provide guidance for the design of fuel elements.
