Engineering design of the ARIES-RS power plant

ARIES-RS is a fusion power plant design study which has examined the ability of an advanced tokamak-based power plant to compete with future energy sources and play a significant role in the future energy market. A steady-state reversed shear tokamak currently appears to offer the best combination of good economic performance and physics credibility for a tokamak-based power plant. In this article, the engineering design features of the ARIES-RS power core are described, with an emphasis on features adopted to meet the top-level requirements, on design integration advances, and on the key issues for further research and development.
