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 potential of a catalyzed fusion-driven fast hybrid blanket to regenerate Canada deuterium uranium (CANDU) spent fuel is investigated. The investigations are done to achieve enrichment grades of fissile isotopes (EGFIs) in four applications: 1. recycling in a conventional commercial CANDU reactor (EGFI = 0.71 to 0.9%) 2. recycling in an advanced conceptual CANDU reactor with a high burnup rate (EGFI = 1%) 3. recycling in an advanced breeder with thorium fuel (EGFI > 1.5%) 4. recycling in a conventional light water reactor (LWR)(EGFI>3%). The regeneration periods of 5 to 7, 6 to 9, 12 to 15, and >30 months, respectively, are evaluated for the four reactor types under a first-wall fusion neutron current load of 1014(2.45-MeV n)/cm2-s and 1014(14.1-MeV n)/cm2-s, corresponding to 2.64 MW/m2 and a plant factor of 75%. During the regeneration process, the burnup rates vary from 2000 MWd/t (for conventional CANDU) to 10000 MWd/t (forLWRs), so that multiple recycling becomes possible.
