GAIN makes diverse selections for its third round of awards this year
The Department of Energy’s Gateway for Accelerated Innovation in Nuclear has recently awarded four third-round fiscal year 2026 vouchers to support the development of innovative nuclear technologies. Each company will get access to specific capabilities and expertise in the DOE’s national laboratory complex—in this round of awards Idaho National Laboratory, Oak Ridge National Laboratory, and Sandia National Laboratories are named—and will be responsible for a minimum 20 percent cost share, which can be an in-kind contribution.

Experimental and theoretical work on the stellarator concept has established its position as the best alternate concept for fusion power. Its plasma properties are comparable to, or better than, those obtained in comparable tokamak devices. Confinement and transport should be adequate for reactor operation, with high-β operation possible. Although the coil configurations in present experiments are complicated, stellarator reactors could be simpler than tokamaks. The possibilities of steady-state operation, little recirculating power, good start-up and control properties, no disruptions, modular construction, and a built-in divertor make it an obvious direction for tokamak evolution as well as a viable alternate concept in its own right.
