Abstract

The PF (Polodial Field) superconducting magnets for the KSTAR (Korea Superconducting Tokamak Advanced Reactor) are operated in the high rates of change in the operating currents. Under the normal discharging condition of plasma, the current in superconducting magnets can generate the high electromagnetic stress in CICC (cable-in-conduit-conductor) and its support structure. In order to simulate the peak value stress in PF superconducting magnet so that the support structure can be designed to bear the stress, ANSYS is used to study the variation of stress and strain distribution with time. In the paper, the detailed finite element model and numerical results are presented.
