Electromagnetic analysis for blanket of fusion reactor under plasma disruption

In a fusion reactor, the blanket is one of the core components inside the vacuum vessel, it is directly facing the plasma, and the working environment is very harsh. In this paper, the induced eddy current and suffered electromagnetic force in the blanket of China Fusion Engineering Test Reactor (CFETR) has been calculated by the vector electromagnetic method of ANSYS in the major plasma disruption or the vertical displacement event. The modeling, the current source loading, boundary conditions setting, solving and calculated results are presented. This will provides the necessary reference data and method for future detailed design and optimization of the blanket components. (authors)
