Discrete Alfvn eigenmodes in steady-state operation scenarios with negative magnetic shear in the international thermonuclear experimental reactor are investigated in this paper. These magnetohydrodynamic eigenmodes are trapped by the α-induced potential wells along the magnetic field line. Here α =-q2Rdβ/dr with q being the safety factor, β the ratio between plasma and magnetic pressures, and R the major radius, and r the minor radius. Due to negligible continuum damping via wave energy tunneling, these Alfvn eigenmodes could be readily destabilized by energetic particles.
