Description
In 2024, EUROfusion consortium released a new DEMO baseline with a slightly reduced aspect ratio (A=2.8 instead of 3.1), major radius (8.6 m instead of 9.1 m) and magnetic field (4.4 T instead of 5.2 T on the plasma axis) compared to the previous 2018 baseline. The fusion power is targeted to 1.65 GW. The design of all DEMO magnets have been updated in 2025. In this study, we present the thermo-hydraulic analysis of the TF coil based on the flat react&wind Nb3Sn conductor. The coil design aims at optimizing the material and manufacturing costs of the TF coils, and simplifying the manufacturing process. The thermo-hydraulic analysis investigates the possibilities of reducing the magnet’s operating costs and increasing the coil robustness against unforeseen degradation of its superconducting properties or higher-than expected heat load, both requiring increased cooling power.
