辐射屏蔽设计是反应堆设计的重要组成,面向陆海空天全域的新型核动力技术的发展对辐射屏蔽优化设计方法提出了新需求。采用传统屏蔽结构多目标优化方法处理三维屏蔽结构优化问题时,存在寻优速度慢、难以收敛、全局性差等缺陷,基于第三代非支配排序遗传算法(Non-dominated Sorting Genetic Algorithm Ⅲ,NSGA-Ⅲ),开展面向三维屏蔽结构设计的高维多目标优化方法研究。基于核反应堆三维屏蔽结构模型,以屏蔽层重量、体积和特定区域辐射剂量率为优化目标,开展NSGA-III优化方法的性能对比分析研究。数值结果表明:本文建立的高维多目标优化方法可更高效、稳定地搜寻Pareto前沿解,可为辐射屏蔽设计优化...

[Background] Radiation shielding design is an important part of reactor design, and the development of new nuclear power technology for various kinds of reactors has put forward new demands on radiation shielding optimization design methods. [Purpose] This study aims to overcome the shortcomings of the traditional multiobjective optimization methods for shielding structures in dealing with the optimization problem of 3D shielding structures, such as slow optimization speed, difficulty in convergence, and poor globalization. [Methods] Based on t...
