“…It is now being considered as the lead concept for the US ITER blanket test module [6]. A modular concept was adapted for the ARIES-CS compact stellarator geometry with a particular focus on developing a more efficient coolant routing configuration and on optimizing the design performance of the blanket coupled to a Brayton power cycle through a heat exchanger system [7]. The cycle working fluid (He) is routed through the blanket He heat exchanger first and then in an optimized parallel arrangement through the blanket Pb-17Li heat exchanger and the divertor He heat exchanger.…”

Optimization of the stellarator configuration requires tradeoffs among a large number of physics parameters and engineering constraints. An integrated study of compact stellarator power plants, ARIES-CS, aims at examining these tradeoffs and defining key R&D areas. Configurations with a plasma aspect ratio of A ഛ 6 and excellent quasiaxisymmetry ͑QA͒ in both two and three field period versions were developed while reducing ␣-particle losses to Ͻ10%. Stability to linear ideal MHD modes was attained, but at the expense of reduced QA ͑and increased ␣-particle losses͒ and increased complexity of the plasma shape. Recent experimental results indicate, however, that linear MHD stability limits may not be applicable to stellarators. By utilizing a highly efficient shield-only region in strategic areas, the minimum standoff was reduced by ϳ30%. This allows a comparable reduction in the machine size. The device configuration, assembly, and maintenance procedures appear to impose severe constraints: three distinct approaches were developed, each applicable to a certain blanket concept and/or stellarator configuration. Modular coils are designed to examine the geometric complexity and to understand the constraints imposed by the maximum allowable field, desirable coil-plasma separation, coil-coil spacing, and other coil parameters. A cost-optimization system code has also been developed and will be utilized to assess the tradeoff among physics and engineering constraints in a self-consistent manner in the final phase of the ARIES-CS study.
