Westinghouse says eVinci microreactor is designed to power U.S. military installations continuously for eight years without refueling

The U.S. Army selected Westinghouse's eVinci heat-pipe microreactor for the next phase of the Janus Program, an effort supported by the Defense Innovation Unit to provide resilient power at military installations. Westinghouse says the transportable design is intended to supply continuous electricity for up to eight years without refueling, reducing dependence on vulnerable fuel deliveries and external grids. Selection advances the company into site-specific development with one of nine candidate installations and milestone-based work toward commercial hardware, but it is not an operational deployment and the Army did not identify the site, output rating, cost, or fielding date.
