摘　　要：针对先进栅格计算程序KYLIN-Ⅱ的共振计算模块,开展了多个基准题数值验证,包括单栅元、IAEA板型燃料组件、钍基组件、多层套管型燃料组件、带可燃毒物的燃料栅格、带中心大水腔的超临界水堆燃料栅格、AFA3G含钆燃料组件基准题。验证结果表明,本文的共振计算模块适用于棒栅元方型组件、板型燃料组件、六角形组件等几何结构较复杂的问题,同时可以正确计算含有铀、钍、毒物等复杂材料的共振问题,满足未来工程使用的需求。Several benchmark problems were validated for the resonance calculation module of neurotics lattice code KYLIN-Ⅱ,including cell problem,IAEA problem,thorium based assembly problem,multi-layer bushing fuel assembly problem,burnable poison lattice problem,supercritical water reactor fuel lattice with large water cavity,and AFA3G fuel assembly with Gadolinium problem.The validation results show that the resonance calculation module in this paper is suitable for complex geometric structures such as square assembly with fuel rod lattice and planar fuel assembly and hexagonal assembly.Besides,it can correctly calculate the resonance problem of complex materials containing uranium,thorium,poisons,etc.It satisfies the requirement of future engineering application.
