英文摘要	In this paper, NOVA/NOVA-K codes are used to investigate the stability of Alfven eigenmodes (AEs) in the China Fusion Engineering Test Reactor (CFETR). Firstly, the stability of AEs excited by energetic alpha particles is investigated. For the fully non-inductive scenario, it is found that all AEs are stable, and the least stable toroidal mode number is n = 8. However, for the hybrid mode scenario, it is found that many AEs are unstable, and the least stable toroidal mode numbers are n = 7, 8. Secondly, the effect of energetic alpha-particle parameters and beam ions on AE stability is also presented. The threshold of the least stable AE is about beta(crit, alpha) = 1.12%, less than the value of alpha-particle beta (beta(alpha) = 1.34%). The result demonstrates that the AEs excited by alpha particles are weakly unstable. The effect of the beam ions on AE stability is found to be very weak in CFETR.
