Towards systems code studies for a general class of stellarators — •Jorrit Lion and Felix Warmer — Max Planck Institute for Plasma Physics, D-17491, Greifswald, Germany

Stellarators are attractive candidates for a fusion power plant owing to their inherent steady-state capability and absence of disruptions. A convenient way to study different power plant designs is by applying systems codes, which aspire to model an entire fusion power plant within a single framework. Here, we present general modules for the systems code PROCESS to enlarge the possible configuration space compared to earlier works, focusing on a modular coil model, a support structure model and a bootstrap current model for quasi-axisymmetric stellarators. These models reflect the full 3D geometry of the stellarator coils and are incorporated in PROCESS via scaling laws and fits for specific devices. We further present first results from a modified version of PROCESS using these models, applied on certain stellarator designs with different aspect ratios.
