Stellarator fusion power plants

In the stellarator community, a broad variety and diversity of three-dimensional magnetic configurations exist. In this chapter, the respective power plant studies of the major helical magnetic confinement concepts are presented, namely for the heliotron, the advanced stellarator and the compact stellarator concept. Since the diversity of the magnetic configurations is also reflected in the proposed technological solutions, the individual engineering concepts (in particular for blanket and divertor) are presented and brought in context by their advantages and drawbacks. Further, an outlook is given regarding the current developments and future prospects of stellarator fusion power plants.
