Abstract: The work is directed to description of nonlinear three-dimensional numerical MHD code NFTC for investigation of thermonuclear plasma in Tokamak devices. The statement of problem is suggested on the base of neoclassical equations of nonlinear model. The excitation of instabilities are discussed. The approaches for resolving of the instabilities problems solution is presented. Numerical methods for resolving of plasma instabilities and the accuracy of solutions are determined. The examples of instability calculations are presented for international thermonuclear device ITER. The work is directed to description of nonlinear three-dimensional numerical MHD code NFTC for investigation of thermonuclear plasma in Tokamak devices. The statement of problem is suggested on the base of neoclassical equations of nonlinear magnetohy - drodynamics model.

Keywords: mathematical modeling, nonlinear MHD equations, plasma instability, thermonuclear devices.
