The work presented us devoted to simulation of a stellarator reactor based on the Helias concept with the help of the 1-D time-dependent predictive transport code ASTRA. The discharges are described by three diffusive equations for the electron density and the electron and ion temperatures. The self-consistent radial electric field is determined from the ambipolarity constraint. A neoclassical transport matrix including non-diagonal elements has been employed. The model of the reactor plasma has been further developed. A start-up scenario driven by electron cyclotron resonance (ECR)-heating has been calculated. The rise of plasma density is provided by injection of deuterium-tritium pellets. The heating power required for ignition and burn coincides with that derived from POPCON calculations. A regime with a hollow density profile is also presented. The main improvement in the plasma model are described.
