AC Losses Calculations for the ITER Correction Coils During Plasma Operation

While the ITER magnet system assembly is progressing, models are being developed to predict the performances of the coils in preparation of the ITER magnet commissioning and operation. In particular, the AC losses generated in the conductors during a plasma scenario need to be estimated in order to predict the magnet thermo-hydraulic performances. The largest AC losses during plasma operation are expected in the CS (Central Solenoid) and PF (Poloidal Field) coils and the respective AC loss estimations were previously published (P. Bauer et al. 2023). This paper discusses the results of simulations of AC losses in the ITER Correction Coils (CC) during the long ITER plasma pulse. These calculations take into account the electromagnetic screening by the ITER passive structures, most importantly the vacuum vessel, showing its impact on the AC losses. The results are also compared to earlier predictions.
