A Combined Electromagnetic and Mechanical Approach for EU-DEMO Toroidal Field Coils

The roadmap to fusion electricity of the European scientific program aims at realization future DEMOnstration (DEMO) power plant. In 2020, pre-concept design phase DEMO was completed, defining concept and characteristics main magnets structures machine. Sixteen toroidal D-shaped magnets, six poloidal annular coils a central solenoid constitute functioning system core. reactor is subjected huge mechanical loads, mainly due Lorentz force produced by combination high magnetic fields operative currents. As consequence, loading conditions are extremely demanding for structural components, it crucial complete comprehensive static fatigue assessment before proceeding with next iteration. This work focuses on electromagnetic analyses performed field coil its support present methodological approach developed. Exploiting finite element method, three-dimensional model has been defined obtain loads time points reference plasma scenario then transfer them related 3D model, corresponding discretization one. used displacement stress various perform evaluation as well assessment.
