Analysis of electromagnetic loads on EU-DEMO inboard and outboard blanket vertical segments

An analysis of the EM loads acting on a DEMO reactor configuration based on Multi Module Segment (MMS) design is presented in this work as part of the ongoing EU DEMO studies. Lorentzʹs forces and moments, both on the single module as well as on the complete blanket segment, are calculated for both the European HCPB and HCLL concepts. The system is analyzed considering a major central disruption scenario with a linear current quench of 42 ms using the ANSYS finite element software. The results are also compared to linear analyses to underline the effect of the non-linearity of the ferromagnetic materials.
