摘　　要：为详细研究快堆组件棒束中的流动与换热两方面因素对组件热工水力特性的影响,本工作采用克里金方法研究快堆燃料组件的设计参数。由计算结果可知:保证组件出口平均温度不变,随组件压降的升高,满足条件的P/D和H/D范围变化有一定的方向性,逐渐靠近原点;保证组件棒束的压降不变,随组件出口平均温度的升高,P/D和H/D范围变化不具备方向性。根据计算结果可在给定输入限值条件下得到组件满足条件的设计参数范围,可为今后大型快堆的燃料组件选型提供参考。In order to study the influence of flow and heat transfer on the thermalhydraulic characteristics of fast reactor fuel assemblies,the Kriging method was used to study design parameters of the assemblies.The result shows that the P/D and H/D ranges change gradually in a certain direction towards the origin,when the pressure drop of the assembly increases with constant average outlet temperature.While the P/D and H/D range change is not directional when the average outlet temperature of the assembly increases with constant pressure drop.According to the calculation results,the design parameters of assemblies can be obtained under given input limit conditions,which can provide reference for the selection of fuel assemblies for larger fast reactors in the future.
