Selected results of AC loss tests from the recent (2014) campaign on the Experimental Advanced Superconducting Tokamak at ASIPP Hefei, China, are presented and discussed. The state-of-the-art thermal-hydraulic code 4C is then applied to deduce, from the available measurements, the coupling time constant nτ value for the CS conductor. It is found that nτ ∼ 30 ms could explain the experimental results. The computed evolution of temperatures and mass flow rates is compared with experimental data, validating the code in cases not used for its calibration.
