Electromagnetic and mechanical analysis of CFETR toroidal field coils
2015
Abstract The toroidal field (TF) magnets of the China Fusion Engineering Test Reactor (CFETR) provide a steady magnetic field with peak value of 11.5 T. Enormous electromagnetic forces are generated on TF structures due to the high magnetic field and large current. Structural analysis of TF coils is required to investigate the feasibility of the current design scheme and to provide guidance for optimization. The design status is described and electromagnetic analyses of different current scenarios are reported. The results of the mechanical analysis show that TF structures can safely withstand the reference operational scenarios, and the fatigue life can be assumed to be infinite based on the results of this fatigue assessment.
