description: This work is devoted to the study of the effect of massive gas injection, as well as central and chordal injection of pellet, on the disruption of tokamak plasma. Tasks that were solved during the study: 1. Classification of experimental results, their comparative analysis. 2. Simulation of transport processes in plasma with allowance for gas puffing, formation of runaway electrons and pellet evaporation. The work was carried out on the basis of the T-10 tokamak located at the Kurchatov Institute. All experimental data were taken from the database of discharges in the T-10 tokamak. Their primary processing was carried out and the corresponding graphs were built. The modeling of transport processes in the plasma of the T-10 tokamak with the ASTRA code has been performed, for which the corresponding programs have been written. Further, a comparative analysis of the plasma parameters for different types of injection is carried out. As a result, the injection methods are ordered according to the rigidity of the current quench: massive gas injection from the far zone, one from the near zone, central pellet injection, and the most severe disruption was caused by chord injection. The simulation data correspond to the experimental ones; therefore, the methods proposed in this work to take into account the massive gas puffing into the tokamak plasma, the evaporation of the pellet, and the formation of runaway electrons during stripping make it possible to qualitatively predict the experimental results. An increase in the radial magnetic field was revealed at a larger angle of deviation of the pellet injection from the central axis.
