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.

UNITY-2 (UNique Integrated Testing facilitY) is a facility designed to replicate the architecture of the deuterium-tritium fuel cycle of a fusion pilot plant (FFP) on a smaller scale. The facility will operate continuously at a steady-state flow rate of 2.3 Pa m3 s−1 using gas puffing, and will allow for the injection of fuel pellets for shorter periods with up to 27.5 Pa m3 s−1. UNITY-2 will demonstrate a fully integrated deuterium-tritium fuel cycle using a license for up to 30 g of tritium at Chalk River Laboratories, therefore reducing the risk of producing a FFP on a decadal timeframe. Its novelty, relative to past and planned fuel cycle experimental demonstrations, lies in the continuous and fully integrated operation, an inner fuel cycle that includes a direct internal recycling loop, an inner and outer loop, and a breeder cycle based on lithium lead coolant. UNITY-2 has a full suite of detritiation systems to demonstrate as low as reasonably achievable releases. Following the successful integrated operation, the technology readiness will reach a maturity to be applied to FFPs.
