Portsmouth Project

The Portsmouth Gaseous Diffusion Plant, located in Piketon, Ohio (approximately 22 miles north of Portsmouth and 75 miles south of Columbus), is owned by the U.S. Department of Energy (DOE). The Environmental Management mission includes environmental cleanup and waste management; the Enrichment Facilities mission includes management of depleted uranium hexafluoride generated prior to the highly-enriched uranium (HEU) shutdown and removal program, and maintenance of non-leased buildings and grounds.
