The operating characteristics in the poloidal field (PF) coils system of KSTAR ( Korean Superconducting Tokamak Advanced Research ) for given operating scenarios are analyzed by SAITOKPF. In order to control the plasma shape in KSTAR to realize the thermal nuclear fusion reaction, the operating currents in PF coils are controlled with high various rate with respect to time. The induced current in the support structure and cryostat generates high eddy losses. It also produces the large hysteresis, eddy and coupling losses in superconducting coils. The supercritical helium with high velocity through the cable-in-conduit-conductor (CICC) removes the heat load to keep the temperature of superconducting cable lower than its current sharing temperature. The maximum temperature rise in PF1 is studied under the various inlet pressures for helium (He) while the output pressure of He is kept constant of 3Mpa. The single and continuous operating scenario for KSTAR are studied to decide the maximum temperature rise and total AC losses.
