UWFDM-1336 Overview of ARIES-CS In-Vessel Components: Integration of Nuclear, Economics, and Safety Constraints in Compact Stellarator

The recent development of the compact stellarator concept delivered ARIES-CS – a compact stellarator with 7.75 m average major radius, approaching that of tokamaks. In stellarators, the most influential engineering parameter that determines the machine size and cost is the minimum distance between the plasma boundary and mid-coil (∆min). Accommodating the breeding blanket and necessary shield within this distance to protect the superconducting magnet represents a challenging task. Selecting the nuclear and engineering parameters to produce an economic optimum, modeling the complex geometry for 3-D nuclear analysis to confirm the key engineering parameters, and minimizing the radwaste stream received considerable attention during the ARIES-CS design process. This paper provides a perspective on the successful integration of the nuclear activity, economics, and safety constraints into the final ARIES-CS configuration.
