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.

Inductive formation and sustainment of spheromaks are examined. The S-1 device utilizes a flux core to form a spheromak inductively. Plasmas are observed to relax during formation toward a minimum energy state, independent of initial conditions. Inductive sustainment of spheromaks is considered possible by utilizing this relaxation process. One method uses a poloidal flux transformer along the major axis, similar to the ohmic heating transformer in a tokamak. Alternatively, spheromaks can be established with the outermost poloidal field lines linked around the flux core to provide coupling between the plasma and external circuits. The spheromak configuration then can be sustained by oscillating the currents in the poloidal and toroidal field coils within the flux core. These proposed current drive schemes are investigated using the concept of magnetic helicity injection.
