Half test-bed, half nuclear engineering school, Fort Belvoir’s SM-1 was decommissioned in 1973 and its nuclear core dismantled, after having served longer than any of the Army power plants that came after it. It was briefly opened to the public as a museum in 1975, and continued to serve as a training facility before being closed permanently in 1977. The cooling tower and containment dome are still visible from the Potomac River. Stationary Medium Power Plant 1, the birthplace of peacetime Army nuclear power generation, will likely be demolished around 2030, 50 years after it split its last atom.
