Internal kink mode, as an effective factor in disruptions, and it's stability in IR-T1 tokamak (with circular cross-section plasma) is studied. Due to the rapid change of this mode with the safety factor, considering a common profile for toroidal current density leads to the safety factor and growth rate of the internal kink instability profiles. With increasing of the υ values, the safety factor at inner parts of the plasma drops below one and we have the instability growth in these areas. For the smaller υ values, the mode is stable everywhere in this tokamak.
