The circle-in-square cable-in-conduit conductor that will be adopted for the 3L module of the ITER Central Solenoild (CS) coil has been recentyl tested to assess its performance in conditions relevant for the real operation of the magnet. The tests on a 43-m-long condutor were performed in the CS Insert Project carried out under the responsibility of the US ITER Domestic Agency, in charge of the CS modules manufacturing. In this paper, wer present an evaluation of the ac losses of this conductor aiming at the assessment of the nTau value for the conductor coupling losses. The electromagnetic (EM) and thermal-hydraulic (TH) analysis of these experiments in then performed.
