X-Energy Reactor Company and the U.S. Department of Energy (DOE) have signed a cooperative agreement to advance the development of a mobile microreactor design. The agreement supports X-energy's work on the preliminary design of its transportable nuclear power plant. The DOE has awarded approximately $2.5 million to X-energy for this project. The Department of Defense (DOD) has also expanded its agreement with X-energy to develop a cost-effective design for a transportable advanced nuclear microreactor prototype for use in remote military locations.
