Abstract：The China Fusion Engineering Testing Reactor (CFETR) is a superconducting Tokamak device.The poloidal field (PF) magnets of the CFETR play an important role in controlling the location and shape of the plasma.The stable operation of the PF system is largely based on the cable-in-conduit conductors (CICC) stability.In order to insure the stable operation of the PF system,the analysis of the CICC for PF system is performed by the Gandalf program.For stability analysis,a mechanical disturbance and an electromagnetic disturbance are applied,respectively.The calculation of stability margin,minimum quench energy and temperature margin are presented in this paper.The dependence of the current sharing temperature on the operating current and the background field are discussed.And the quench characteristics are studied.Moreover,as an important factor which influences the stability of conductor,the AC loss is calculated and its effect on the stability of conductor is studied.The analysis results illustrate that the present design of CFETR PF conductor can sufficiently satisfy the requirement of safety margin.
