Internal kink mode has been considered as an effective factor in disruptions and according to this issue, its stability in IR-T1 tokamak (circular cross-section plasma) has been investigated. Tokamak plasma stabilization against this mode is provided by a suitable profile for the safety factor. By considering a common profile for toroidal current density, corresponding profiles for the safety factor and growth rate of the internal kink instability were obtained for IR-T1 tokamak. The results show the highest stability in the plasma boundary regions for all ν values and the highest instability in the central plasma regions for values of ν > 3. Also, comparing between these results with the findings of data fitting with one of the main codes in the field of this instability, shows a good agreement for the order of growth rate of instability.
