The code package PROCESS is a tool widely used for Tokamak systems studies. In this study, however, the application of PROCESS to Stellarators is addressed. In order to incorporate a Stellarator module in the systems code PROCESS, Stellarator-specific models are considered which reflect the differences due to the confinement concept. These include: a geometry model based on Fourier coefficients which can represent the complex 3-D plasma shape, a divertor model which assumes diffusive cross-field transport and high radiation at the X-point, a coil model which is a scaling based on the Helias 5-B design and a transport model which employs a confinement time scaling derived from empirical scalings and by sophisticated 1-D neoclassical and anomalous calculations. This approach is investigated to ultimately allow one to facilitate a direct comparison between Tokamak and Stellarator power plant designs.
