Shipping container-sized nuclear reactor enters build phase to power US military bases
AI Article Summary

BWX Technologies has commenced work on the Pele microreactor, a 1.5-megawatt system designed to power U.S. military bases and remote locations. The reactor, small enough to fit in shipping containers, is expected to produce energy by 2028 and can operate for three years without refueling. Rolls-Royce and Northrop Grumman are key partners in the project, which also has potential applications for disaster response and research stations. The microreactor technology reflects advancements initially intended for space exploration but is now being adapted for terrestrial use.
