TL;DRAbstract
The Helias stellarator reactor is an upgrade version of the Wendelstein 7-X device taking into account the design criteria of a power reactor.The dimensions of a Helias reactor are: Major radius 22 m, average plasma radius 1.8 m, magnetic field on axis 4.75 T, fusion power about 3000 MW.Neoclassical transport sets a lower limit on plasma confinement, and extensive numerical calculations have been done to clarify this issue.Extrapolating empirical scaling laws to a Helias reactor shows that anomalous confinement determines the ignition conditions.The effect of parameter variations on ignition is studied.The result of these zero dimensional calculations is also compared with start-up scenarios obtained with the ASTRA code.
