Mechanical analysis of the PF1 feeder for ITER

The ITER experimental device contains very powerful superconducting magnets operated at cryogenic temperatures to generate and control the deuterium–tritium plasma for thermo-nuclear fusion. The function of the feeders is to convey the cryogenic supply and electrical power through the warm-cold barrier to ITER magnets. Due to the complexity of the structure and working conditions, a global mechanical analysis is required to have simulation information to check the structural reliability of the design. Electromagnetic force analysis of PF1 feeder for further mechanical analysis was calculated under the worst scenarios with the maximum working current in every coil. Mechanical analysis model was built using the finite element software ANSYS. The structural performance of the PF1 feeder was analyzed. The numerical simulation results show that the design of the PF1 feeder is feasible.
