The selection follows a record-setting performance by the company earlier this year. On June 30, 2026, the Unity reactor achieved criticality just 150 days after its project kickoff, fulfilling a federal mandate under Executive Order 14301. By utilizing the DOME testbed—housed within the former Experimental Breeder Reactor-II structure—Deployable Energy intends to bypass the need for bespoke infrastructure, instead validating its reactor's ability to be factory-fueled, transported, and redeployed.
Deployable Energy to Conduct Full-Power Reactor Test at Idaho Lab
Deployable Energy has secured a pivotal testing slot at the Idaho National Laboratory’s DOME facility, marking the next phase in the development of its Unity Nuclear Battery. The 2027 campaign aims to demonstrate full-power operation for the modular system, pushing the technology toward commercial readiness and mass production.

CEO Bobby Gallagher emphasized that the company’s approach centers on rapid development cycles that do not sacrifice safety or quality. During the upcoming campaign, the team will execute a series of operational firsts, including the transport and installation of a fueled reactor, followed by a transition to a new location within the laboratory. This lifecycle demonstration will provide the Nuclear Regulatory Commission with the necessary data to support future licensing efforts. John Wagner, Director of Idaho National Laboratory, noted that the DOME facility was specifically designed to host a succession of developers, validating Deployable Energy's progress as a model for effective public-private collaboration.
