[en] A program complex designed for analysis of transport processs in a tokamak is described. The given system differs from the programs which are currently used by the fact that the user can do without programming languages. Transport phenomena are written in the form maximally closed to the form of equation writting in articles. To record transport coefficients, various elementary and other processes one can use library formulas describing a wide set of physical processes. Creation of a program of numeric solution on the base of assigned equations of analysis or calculation of transport processes is realized in TRANSITOR system automatically

[en] Review of modern state of neoclassical theory, concerning plasma rotation in a tokamak at minor rates (as compared to the thermal one) is given. The prevailing style of the work is the hydrodynamic one, which allows one to trace the conservation laws and the relationship between toroidal pulse relaxation and plasma diffusion processes. Kinetic coefficients are calculated using simple gaseous-kinetic estimations and their values, obtained from kinetic equation solution, are given as references. Results of neoclassical theory for plasma rotation at high rates are briefly presented. The role of anomalous processes is also considered

[en] A general system of equations is obtained for determining diffusion rates and heat flows in a multicomponent plasma with arbitrary mass ions, being in arbitrary charge states. Heat and particle flows across a magnetic field in a multicomponent magnetized plasma are calculated, which permits, in particular, to fully analyze the temperature shielding effect as well as the transverse heat transfer in a plasma with several types of ions. While determining transfer longitudinal properties the possibility of summing up ions of one type by their charge states is grounded. The expression obtained together with the calculated coefficients for a plasma with two types of ions can be used at the analysis of radial transfer of impurities (in particular, carbon, oxygen, tungsten and iron impurities) in toroidal systems in the Pfirsh-Schluter regime

[en] Even when the hydrodynamic approximation is satisfied on average, i.e., when the mean free path is much less than the characteristic longitudinal gradients, the expressions for the classical heat conductivity and viscosity coefficients turn out to be overestimated. This is due to the fact that the hydrodynamic heat and momentum fluxes are determined by the tail of the distribution function and become essentially nonlocal by nature. In the paper the Grad method is used to determine the transport structure. The integral expressions for the longitudinal heat and momentum fluxes are obtained

[en] The nonlinear problem of the anomalous diffusion of electrons in a tokamak at interaction with electromagnetic fluctations is considered consessively for the first time. Self-consistent theory of space diffusion of electrons in electromagnetic fluctations of arbitrary amplitude in a tokamak is constructed with account of toroidal drift. It is shown that diffusion is determined by banana electrons with a certain characteristic time of stochasticity, and a characteristic scale of diffusion in a nonlinear case in wave amplitude is saturated

[en] A form-factor in the expression for a absorbed power of resonance particles in a tokamak during cyclotron heating at ωΩsub(Ca) is calculated. Evaluations for possible mechanisms of radiative transfer, arising due to cyclotron wave-particle interaction, are obtained. It is pointed to possible concentration of particles near a resonance zone, that is the reason for plasma polarization and occurrence of a poloidal electric field. The ''neoclassical'' ion flow evaluations obtained in the presence of this field can apparently explain the observed difference in particle confinement while icr and ecr plasma heating in the tokamak

[en] Transfer of impurities of an arbitrary charge and a mass in toroidal systems is considered. Expressions for the diffusion and heat fluxes of impurity ions are obtained on the basis of hydrodynamic equations with kinetic coefficients calculated for an arbitrary ion mass ratio. The condition of temperature screening of the impurity is derived, which may hold true in the regions of abrupt drop in temperature along the filament radius at z(<=)4 (Z is the ion charge). The effect of heat exchange between plasma components of the ion diffusion is analyzed. It is shown that a decrease in heat exchange between the ions and heat exchange with electrons reduce the screening effect
