NANO Nuclear Energy's novel heat exchanger concept, intended for use in the Zeus microreactor, a technical audit of the Antares R1 thermosiphon-cooled microreactor, a study to develop purity tests for molten salts, and a screening process to identify potential sites for nuclear-powered data centres have been chosen to receive funding from the US Department of Energy Office of Nuclear Energy's Gateway for Accelerated Innovation in Nuclear (GAIN) programme.
