The paper describes the calculation data on the physical parameters of a reactor-stellarator, where the nonuniformities of the helical field are smaller than the toroidal magnetic field nonuniformities: εh < εt. Unlike the previous studies, where the ion-component transport coefficients had the collision frequency dependence proportional to ν1/2, this being equivalent to the εh > εt case, in the present calculations, these coefficients were assumed to be in proportion to the first power of the collision frequency, Di ∝ ν for νeff < 2ωE, and to Di ∝ ν−1 for the inverse inequality. Here, ωE is the rotation frequency of plasma in the radial electric field. As before, the plasma electrons corresponded to the mode of De ∝ ν−1. As initial parameters for numerical calculations, a reactor with R = 8 m, rp = 2 m, and B0 = 5 Т was taken. A numerical code was used to solve the set of equations that describes the plasma space−time behavior in the reactor-stellarator under the conditions of equal diffusion fluxes. The start of reactor operation in the mode of thermonuclear burning was provided by heating sources with a power of several tens of megawatts. Steady-state operating conditions of a self-sustained thermonuclear reaction were attained by maintaining the plasma density through DT fuel pellet injection into the plasma.
