摘 要: | 蒙特卡罗程序已经广泛应用在裂变反应堆设计和验证过程中,快速获得高效的计算模型可以有效缩短反应堆的设计周期。本研究提出并实现了一种裂变堆芯快速蒙特卡罗建模的方法,该方法基于参数可视化和层次化两种建模思想快速构建出精细裂变堆芯计算机辅助设计(Computer Aided Design,CAD)模型且将其快速转换成蒙特卡罗计算模型,同时采用一种新的堆芯分段管理方法实现了大规模裂变堆模型流畅交互。基于此方法快速构建了加速器驱动次临界反应堆(Accelerator Driven Sub-critical System,ADS)的精细堆芯模型,通过与蒙特卡罗程序计算的参考结果进行对比,证明了此建模方法的高效性和可靠性。

Abstract: | Background: The Monte Carlo (MC) method is widely used in fission reactor design, because of its strongergeometry adaptability and the precise calculation result.The high-fidelity full core simulation demands for detailed fission reactor models, which is hard to build by manual and the conventional Computer Aided Design (CAD)-based modeling method.Purpose:In order tosupport the rapid design offission reactor core with MC method, and generate the detailed MC calculation models,a parameter-based and visual MC modeling method was developed in this study.Method: The method can create the detailed CAD models and convert them into MC models in a high-efficiency way. Meanwhile, the huge amounts of models in fission reactor core can be managed by different segments for supporting smooth interactions.Result: Furthermore, the method was validated by the test of creating the Accelerator Driven Sub-critical System (ADS) reactor models, and the results were agree very well by comparing the reference models.Conclusion:Depending on the test, the detailed fission models were created more conveniently than conventional method andthe numerical calculation results proved the accuracy of the new method. |
