Army Nuclear Power Program

Because of its remote location, Fort Greely was chosen as one of the first US military posts to have a compact, nuclear power reactor to generate heat and electricity, under the auspices of the Army Nuclear Power Program. A nuclear power plant, designated the SM-1A was flown-in and installed between 1960–62, and was based on the Army's first prototype reactor, the SM-1 at Fort Belvoir, Virginia. SM-1A pressurized-water reactor reached initial criticality on 13 March 1962, and was shut down in 1972: the reactor core was removed and sent to the Savannah River nuclear site.
