数值分析在CEFR堆顶固定屏蔽安装过程中的应用

Application of Numerical Analysis in Securing Shield Installation for China Experimental Fast Reactor

摘要: 为解决中国实验快堆（CEFR）堆顶固定屏蔽在施工现场出现的超出预期的变形问题，采用数值方法分析了堆顶固定屏蔽在各种安装工况下的力学响应，并将部分工况的计算结果与安装现场进行的加载试验测量结果进行对比，验证了数值分析的模型和结果的合理性，为确定CEFR堆顶固定屏蔽的安装施工方案提供了参考。

Abstract: On account of unexpected securing shield deformation of China Experimental Fast Reactor, the mechanical responses were studied numerically in different installation cases. The numerical results are not only verified by comparing with actual loading experiments’ results, but also provide important supports for the settlement of the installation scheme.
