Modifications of the fusion reactor systems code PROCESS to general stellarators — •Jorrit Lion, Felix Warmer, and Robert C. Wolf — 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 plasma-current driven instabilities. 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 by using simplified 0D or 1D models to capture relevant reactor constraints. In this work, we report on modifications of the fusion reactor power plant systems code PROCESS to a general class of stellarator configurations. This is achieved by introducing a set of new models in PROCESS, which reflect the stellarator specific constraints of a fusion reactor, like inhomogeneous neutron wall loads, coil-force magnitudes, wall loads by fusion born alpha particle wall loads or stellarator specifics operational boundaries by an electron cyclotron resonance heating scheme. Previous models, as introduced in [1], were adapted and generalized to generic stellarators. Using these modifications, PROCESS now allows for a combined technological, physical and economical assessment of a very general class of stellarator power plants within a systems code framework.
