Abstract: Background:As the core components in the fusion reactor, the breeder blanker takes the role of tritium breeding and energy conversion. A helium-cooled ceramic breeder (HCCB) blanket concept has been put forward for the China fusion engineering test reactor (CFETR) by the blanket integration design team of the Institute of Plasma Physics of Chinese Academy of Sciences. Purpose:The aim is to study the influence of the electromagnetic (EM) transients on the structural design of HCCB breeder blanket. Methods:The eddy current, Lorentz forces and moments are calculated by the transient analysis. The maximum equivalent stress and deformation displacement generated in the components under extreme conditions are obtained by coupling calculation of multi-physical field. Results:The eddy current induced by the EM transients, Lorentz forces, moments, the maximum equivalent stress and deformation displacement generated in the components are obtained by ANSYS. Conclusion:The results show that the maximum equivalent stress and displacement of deformation are satisfied with the requirement of structural safety design. Moreover, this simulation will provide the necessary reference data for future design and optimization support structure of the HCCB breeder blanket.
