A 1-MWe gas-cooled microreactor. Designed to fit into a standard 20-foot shipping container, it uses 4.95% enriched uranium dioxide (UO₂) fuel and actively circulating helium gas for cooling. The transportable system is designed to run for over five years before requiring refueling. Deployable Energy's Unity Nuclear Battery is a 1-MWe gas-cooled microreactor.
