Different models have been introduced in the stability code MARS-F in order to study the damping effect on resistive
wall modes (RWM) in rotating plasmas. Benchmarks of MARS-F calculations with RWM experiments on JET and
DIII-D indicate that the semi-kinetic damping model is a good candidate for explaining the damping mechanisms.
Based on these results, the critical rotation speeds required for RWM stabilization in advanced ITER scenarios are
predicted. Active feedback control of the n = 1 RWM in ITER is also studied using the MARS-F code.
