From Idea to Virtual Design: Systems Studies of Stellarator Fusion Power Plants — •Jorrit Lion, Felix Warmer, and Robert C. Wolf — Max Planck Institute for Plasma Physics, D-17491, Greifswald, Germany

Stellarators are attractive candidates for fusion power plants: They operate inherently in steady-state, lack current driven instabilities and do not rely on current drive and or poloidal field coils. To design and model such a power plant, so called systems codes can be applied, which aspire to model all relevant features and constraints of the power plant within a single framework by imposing simplified 0D or 1D models. We report on a new version of the fusion reactor power plant systems code PROCESS, applicable to general stellarator configurations, based on its coil set and the 3D plasma shape [1]. This is achieved by introducing a pre-calculation step to determine effective parameters, which are then being passed to new stellarator specific models in PROCESS. This way, 3D coil-forces, 2D thermal wall loads or stellarator specific operational boundaries can now be modelled within PROCESS. 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. This opens up a new paths to speed up the design cycle and potentially accelerate the deployment of fusion.
