Fusion energy: Progress, partnerships, and the path to deployment
Over the past decade, fusion energy has moved decisively from scientific aspiration toward a credible pathway to a new energy technology. Thanks to long-term federal support, we have significantly advanced our fundamental understanding of plasma physics—the behavior of the superheated gases at the heart of fusion devices. This knowledge will enable the creation and control of fusion fuel under conditions required for future power plants. Our progress is exemplified by breakthroughs at the National Ignition Facility and the Joint European Torus.

A simple, yet comprehensive, model of the divertor region is presented. The model is based on the two-point approach described by Galambos and Peng but has been enhanced to include the key processes of remote radiative cooling, neutral recycling, particle convection, ash effects, and the effects of divertor geometry and plate material. Neutral particle effects are represented using a wedge-shaped section of plasma overlying the divertor plate and a slab attenuation model. The results of benchmarking against four other divertor models demonstrate the applicability of the proposed model. System sensitivities to key parameters are discussed and several general observations regarding divertor design are presented.
