SIMULATION OF THE DISCHARGE SCENARIO IN A TOKAMAK WITH AN IRON CORE

New effective models for the calculation of the discharge scenario are proposed, and numerical algorithms for their realization are develope d. It is shown that for the standard regimes of the operation of a dev ice, when the currents and voltages are under the limiting conditions, these models make it possible to calculate the new discharge scenario during the short time interval between shots. The proposed models are compared with those now in use, and the limits of their applicability are found. Close agreement is shown between the calculation results a nd experiments in the TEXTOR device.
