  The stability of the $n=1$ resistive wall modes (RWMs) is investigated using
the AEGIS code for the newly designed China Fusion Engineering Test Reactor
(CFETR) 1GW steady-state operating (SSO) scenario. Here, $n$ is the toroidal
mode number. Due to the large fraction of bootstrap current contribution, the
profile of safety factor q is deeply reversed in magnetic shear in the central
core region and locally flattened within the edge pedestal. Consequently the
pressure-driven infernal components develop in the corresponding q-flattened
regions of both core and edge. However, the edge infernal components dominate
the $n=1$ RWM structure and lead to lower $\beta_N$ limits than the designed
target $\beta_N$ for the CFETR 1GW SSO scenario. The edge rotation is found the
most critical to the stabilization due to the dominant influence of the edge
infernal components, which should be maintained above $1.5\%\Omega_{A0}$ in
magnitude in order for the rotation alone to fully suppress the $n=1$ RWM in
the CFETR 1GW SSO scenario.
