Facility Description: In 1955, the U.S. Department of the Army (Army) transferred 217 acres of what had been the Weldon Springs Ordnance Works to the U.S. Atomic Energy Commission (AEC) for construction of a uranium feed materials plant. The AEC constructed the Weldon Spring Uranium Feed Materials Plant at this location and contracted with the Mallinckrodt Chemical Company to operate the plant starting in June 1957. The plant was used for uranium refining activities in support of the national defense program. The AEC closed the plant in December 1966 after deciding it was obsolete.

After closing the plant, the AEC transferred the plant and the land back to the Army on December 31, 1967.
