U.S. DOE Environmental Remediation – Paducah Gaseous Diffusion Plant (GDP)

In 2014, the U.S. Department of Energy (DOE) selected Fluor to manage the cleanup at the Paducah Gaseous Diffusion Plant (GDP) in Paducah, Kentucky. Fluor is the prime contractor for the management, integration, and execution of the deactivation and post-GDP shutdown remediation activities of the Paducah Site. This contract is reducing environmental risks and creating local job opportunities. The estimated contract value is $420 million over three years.

Fluor is leveraging its gaseous diffusion plant experience at Portsmouth and its more than 20 years of experience managing and operating nuclear decommissioning sites to deliver the site's program safely and cost effectively.

Client's Challenge

Built in the 1950s as part of the United States' nuclear weapons production complex, the Western Kentucky plant enriched uranium for more than 50 years.

Limited cleanup activities have been underway since 2010, but are now expected to begin in earnest. In addition to mitigating the site's environmental impacts, the contract is also expected to create job opportunities in the area.

Fluor's Solution

In addition to the management of the site, Fluor was responsible for integrating and executing the deactivation and post-GDP shutdown remediation, including soil and groundwater activities at the plant. In 2015, the environmental remediation contractor was successfully transitioned under the Fluor contract, with the support of teaming partners LATA and Chicago Bridge & Iron (CB&I). LATA's experience as the previous environmental remediation contractor, and CB&I's past performance on 21 nuclear decontamination and decommissioning projects complemented Fluor's expertise to meet this deadline.

Key accomplishments to date under this contract include:

  • Consolidated four switchyards into one to reduce surveillance and maintenance costs. Additionally, taking the six main transformers from the switchyards out of service will save the government $642,000 annually.
  • Removed approximately 400,000 gallons of lubrication oil and oil that contains PCBs from electrical equipment, including transformers. Workers used lube oil, already on the site, rather than purchasing a new solvent, to rinse the electrical equipment, which saved a half-million dollars.
  • Demolished 11 inactive facilities with about 270,000 pounds of the resulting scrap metal that is being recycled to offset the cost of the project. Removing hazardous material and demolishing facilities will reduce surveillance and maintenance costs in the long-term.
  • Focused on the accelerated deactivation of the C-400 facility, the historical source of groundwater contamination at the site. Isolation of electrical equipment and removal of asbestos and other material and piping prepared the facility for additional remedial activities.
  • Completed modernization of the on-site groundwater treatment system. Nine new monitoring wells were installed in the northeast section of the site to evaluate optimization of the site's second groundwater treatment system.



Fluor has a long and successful history of performing challenging projects within the DOE Complex. In addition to its current role as the managing partner on the management and operating contract at the Savannah River Site, Fluor serves as the prime contractor for the decontamination and decommissioning of the Portsmouth Gaseous Diffusion Plant in Piketon, Ohio. Fluor also manages and operates the Strategic Petroleum Reserve (SPR) for DOE's Office of Fossil Energy.

Fluor has worked at the Hanford Site in Washington State since 1996, including the role of the site's prime contractor for 12 years. From 1992 to 2006, Fluor executed the Department's first closure contract at the Fernald Site near Cincinnati, Ohio, and completed the project ahead of schedule and under budget.
