Neutronics modeling of 360° China Fusion Engineering Test Reactor and preliminary nuclear analysis

  • 摘要: 基于自动化建模软件平台cosVMPT的发展,建立了包含厂房结构的中国聚变工程试验堆(CFETR) 360°全堆模型,主要结构包括中心螺线管线圈、真空室、纵场线圈、极向场线圈、内外冷屏、杜瓦,以及精细结构的水冷包层和偏滤器。空间布置上包括16个上/下窗口和6个中窗口,2个斜窗口作为NBI束通道,其余窗口内设为屏蔽块。引入“on-the-fly”(OTF)全局减方差方法以获得可靠的中子、光子通量,结果显示其在厂房内的分布不对称。验证了cosVMPT平台和OTF方法的可靠性,并与扇段模型所获得的结果进行对比,进一步确认能够通过扇段模型来简化建模计算过程的使用范围。
