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.

The methods of industrial ecology have been applied to the selection of a high-Z material for indirect-drive targets in the HYLIFE-II reactor. We quantify physical, chemical, and radiological impacts, rate the social-welfare impacts, and identify trends in the economic dimensions of the material selection. Early accident dose, the waste disposal rating, life-cycle volume, gamma dose rate, and resource availability are all considered. Four high-Z materials are considered: Ta, W, Hg, and Pb. A new activation module has been developed to accurately account for the complex activation scenarios of target materials. We explore a range of recycling scenarios and the results of these activation calculations are translated into the indices mentioned above. The recycling scenario can be modified to reduce accident hazards, disposal hazards, maintenance hazards, or fiscal expenditures, but different hazards or costs suggest different recycling scenarios are preferable. The IE methodology and examples of results are presented and areas for further study are identified.
