不同位形大破裂工况下CFETR 真空室预研件的电磁载荷分析

基于数值方法分析了中国聚变工程实验堆真空室预研件(CFETR VV mock-up)在大破裂工况(MD)下不同位形所对应的电磁参数，重点分析了不同位形运行条件下真空室上涡流和电磁力的分布及对比。结果表明，三种等离子体位形下VV电磁载荷分布情况近乎相等，各轴向分力最大值及各分段的最大值存在差异。电磁载荷的获得为进一步校核CFETR VV mock-up的局部结构强度提供了数据基础，对提高真空室的结构设计合理性和运行的安全性具有重要作用。

Evaluation of electromagnetic loads on CFETR vacuum vessel mockup under major disruption events for different configurations

Numerical analysis is performed for the electromagnetic loads on China Fusion Engineering Test Reactor (CFETR) vacuum vessel (VV) mockup corresponding to three different current scenarios during the major disruption (MD) event. The influence of plasma equilibrium configuration on the eddy current and electromagnetic force is emphasized. The analysis results show that distributions of eddy current and electromagnetic force on the VV are nearly same for the three different configurations, while the maxima of the axial force and the maxima of the different segments are different. The electromagnetic loads on VV during major disruption acquired from this method provide the data foundation for further checking the local structural strength of the CFETR VV mockup, and play an important role in improving the structural design rationality and operational safety of the VV.
