SCONE code: Superconducting TF coils design code for tokamak fusion reactor

For fusion reactor design study, a maneuverable design tool of superconductor (SC) TF coils, SCONE code, has been developed. The code was originally developed to apply reactor conceptual design where a baseline design of TF coils is required rather than the detailed one. The code consistently solves heat balance, electromagnetic stress and magnetic field at the TF coil system, and eventually provides the maximum field of the coil system and the optimal material composition of the conductor consisting of SC strand, stabilizing copper, support structure, etc. It was confirmed that the calculated result was reasonable in comparison with existing coil design.
