Current Sharing Temperature Test and Simulation with GANDALF Code for ITER PF2 Conductor Sample

Recently the ITER PF2 coils CICC conductor sample is tested in SULTAN facility. A series of tests are performed. According to the test result, the CICC conductor sample shows stable performance about the current sharing temperature. At the typical PF2 coil operating condition of 45 kA, 4 T and 5 K, the test result of conductor current sharing temperature is 6.71 K, with a temperature margin of 1.71 K. To compare with the result, a thermal-hydraulic analysis of PF2 conductor has been simulated with 1-D model GANDALF code. The test results are consistent with the simulation.
