摘要
船用堆对核反应堆屏蔽设计提出了更高的要求,传统辐射屏蔽设计方法及设计软件已不能满足要求。为了得到更加精确的辐射屏蔽设计,本文基于开源的SALOME框架建立了一套集"几何建模-材料建模-屏蔽优化-结果可视化"功能为一体的船用堆辐射屏蔽多目标优化平台——MOSRT。MOSRT平台可实现屏蔽结构三维CAD实体建模、基于遗传算法的辐射屏蔽多目标优化以及屏蔽计算结果剂量场三维可视化。基于Savannah和MRX船用堆模型对MOSRT平台进行了辐射屏蔽优化验证,优化方案与初始方案相比,在剂量、质量、体积方面均得到了良好的优化效果,证明了MOSRT平台初步具备辐射屏蔽优化设计功能,可为船用堆工程及概念屏蔽设计提供辅助设计手段。
Marine reactor puts forward higher requirements for nuclear reactor shielding design, and the traditional radiation shielding design methods and design software can no longer meet the requirements. In order to obtain more accurate radiation shielding design, this paper establishes a multi-objective optimization platform for radiation shielding of marine reactorMOSRT, which integrates the functions of “ geometric modeling-material modeling-shielding optimization-result visualization” based on the open source SALOME framework. MOSRT platform can realize 3 D CAD solid modeling of shielding structure, multi-objective optimization of radiation shielding based on genetic algorithm and 3 D visualization of dose field of shielding calculation results. Based on Savannah and MRX marine reactor model, the radiation shielding optimization verification of MORST platform is carried out. Compared with the initial scheme, the optimization scheme has achieved good optimization results in dose, mass and volume. It is proved that MOSRT platform initially has the function of radiation shielding optimization design, which can provide auxiliary design means for marine reactor engineering and conceptual shielding design.
