Organization: National Reactor Innovation Center (NRIC)

The U.S. Department of Energy today made conditional selections for Westinghouse and Radiant to perform the first tests in the Demonstration of Microreactor Experiments (DOME) facility at Idaho National Laboratory. The DOME experiments will be the first of their kind in the world and will fast-track the deployment of American microreactor technologies to help keep pace with the nation’s demand for more abundant, affordable, and reliable power. The first fueled reactor experiment will start as early as spring 2026.

NFASE is hosted by the Department of Energy’s National Nuclear Security Administration (DOE/NNSA) with support from the Canadian Nuclear Safety Commission (CNSC). The 4-day experience is designed to help A/SMR developers meet the highest standards of nonproliferation required to compete in the global nuclear market.

U.S. DOE Now Accepting Applications to Schedule Fueled Microreactor Experiments in DOME – the World’s First Microreactor Test Bed

The U.S. Department of Energy (DOE) released a final environmental assessment and proposed finding of no significant impact (FONSI) for the operation of the Demonstration of Microreactor Experiments (DOME) test bed at Idaho National Laboratory (INL). DOME would provide private industry with a safe, reliable, and affordable location to test their microreactor technologies to generate data needed to obtain reactor licensing and commercialization.
