A general stellarator version of the systems code PROCESS

We present modifications of the fusion reactor systems code Process that allow for a description of a general class of stellarator power plants, based on a stellarator coil-set and the respective MHD plasma equilibrium. For this, we modify Process such that each stellarator configuration enters the systems code via a set of effective parameters which can be calculated in advance before using them in new scaling models in Process. Further, we show two applications of the new Process version: firstly, we apply the code to three reactor-size stellarator devices with different aspect ratios, and secondly, to three coil-sets optimized for the same equilibrium with varying coil numbers.

Automated summary

By modifying the fusion reactor system code Process, we are able to describe a general class of stellarator power plants based on stellarator coil-sets and MHD plasma equilibrium. The new version of Process allows for each stellarator configuration to enter the system code via a set of effective parameters, which can be calculated in advance for use in new scaling models. Two applications of the new Process version are demonstrated, including applying the code to three different reactor-size stellarator devices with varying aspect ratios and optimizing three coil-sets for the same equilibrium with different numbers of coils.
