Overview of European efforts and advances in Stellarator power plant studies.

The stellarator concept is a promising candidate for a steady-state fusion power plant, but currently lacking behind the tokamak developments. In order to bring the stellarator concept to maturity, a new EUROfusion Task has been established within the Work Package Prospective Research & Development (WP-PRD) called Stellarator Power Plant Studies (SPPS). This task addresses the stellarator-specific engineering aspects relevant on the way to a fusion reactor. This paper reports on the strategy of this task and provides an overview over ongoing activities as well as initial achievements. [ABSTRACT FROM AUTHOR]
