Abstract: The article presents the results of testing the discharge scenarios developed using the DINA code on the KTM tokamak during the autumn–winter campaign of 2021. The qualitative difference of the developed scenarios is the increase in the plasma current and discharge duration with the unchanged breakdown stage at the bypass voltage of 6 V as well as the presence of a program stage of plasma current reduction before the end of the discharge. In addition, technological limitations in the form of the absence of current reversal in the inductor winding during the discharge and minimization of current reversal in the control windings in the zone of near-zero currents are taken into account. The works conducted in 2021 are the next significant step toward bringing the KTM unit to its design parameters.
