Paducah is the western Kentucky site of a uranium enrichment plant that was built for the Atomic Energy Commission and began operation in 1952. Union Carbide originally operated the plant for the AEC.
The plant eventually was operated by the United States Enrichment Corporation, though the U.S. Department of Energy (DOE), eventual successor to the AEC, owns it.
The Paducah plant was the last operating gaseous diffusion enrichment plant.
USEC says it will wind down enrichment operations over the next month.
Although some activities will continue into 2014, Paducah's run is coming to an end.
