Seismic Analysis of the Support Structure for CFETR TF Magnet

The Magnet Performance Test Facility is an important component of the Comprehensive Research Facility for Fusion Technology (CRAFT). It is used to assess the technical parameters of the toroidal field (TF) magnet for the China Fusion Engineering Test Reactor (CFETR). The support structure of the TF magnet plays a crucial role within the magnet performance test facility. This paper utilizes the seismic response spectrum method to analyze the dynamic response of the support structure during an earthquake. Based on the seismic characteristics of the Hefei area, the maximum von-Mises stress experienced by the support structure is determined to be 33.6MPa, with a maximum deformation of 37.3 mm. The results of the seismic analysis indicate that the support structure satisfies the engineering requirements and demonstrates favorable performance in supporting the TF magnet.
