摘　　要：随着反应堆模型设计的日益复杂,不直观地物理参数设置方式费时且容易出错,大大增加了蒙卡输运计算前期的计算成本。为了增强蒙特卡罗输运软件的可视化程度,本研究以中子输运设计与安全评价软件系统SuperMC为平台,提出了一种基于数据预处理的权窗下边界值分布可视化方法,对生成的权窗下边界值的可靠性进行实时的检查。本文在ITER Clite模型上进行可视化方法的验证,结果表明:借助已有的源信息分布可视化方法,可以直观地检查源位置、能量以及方向分布信息设置的正确性;通过可视化地分析权窗下边界值分布的覆盖趋势和平滑度,能够及时终止生成权窗的迭代过程,输运计算结果也证明使用可视化方法选择的权窗下边界值可以替代人工经验,进一步提升蒙卡软件的易用性。As reactor model designs become more complex,the unintuitive physical parameter setting method is time-consuming and error-prone,which greatly increases the calculation cost in the early stage of Monte Carlo transport calculation.In order to enhance the visualization of the modeling process for Monte Carlo transport code.This study takes Super Multi-functional Calculation Program for Nuclear Design and Safety Evaluation(SuperMC)as the platform,a visual modeling method based on data pre-processing for weight window bounds distribution was proposed to enhance the visualization of Monte Carlo transport software.Combing with existed approach for visualizing complex source distribution,the ITER Clite model with complex physical parameters was adopted to show the effect of the visualization methods.With the help of visualization method,the correctness of source location,energy and direction distribution information can be visually checked.Running code can be terminated according to visually analyzing the coverage area and smoothness of the weight window bounds distribution.The results of transport calculation also prove that the weight window bounds selected by the visualization method can replace the manual experience and further improve the usability of the Monte Carlo software.
