Paducah Remediation Services, Paducah Gaseous Diffusion Plant, Kevil, KY

Portage, as the majority partner in Paducah Remediation Services, LLC (PRS), has performed a variety of environmental remediation and waste management activities at the Paducah Gaseous Diffusion Plant near Kevil, KY. Under this prime U.S. Department of Energy (DOE) contract, we have been responsible for groundwater and soil environmental remedial actions, field investigations, removing legacy waste, decontamination and decommissioning certain inactive facilities, operating site waste storage facilities, surveillance and maintenance, and other activities.


Paducah Gaseous Diffusion Plant

Process Buildings D&D – In a joint venture with Shaw E&I, Portage completed $190 million of decontamination and decommissioning work on the Gaseous Diffusion Process Building and other inactive facilities. Activities included:

  • Verified D&D scope of work in the buildings by reviewing the requirements of the work plan, examining drawings, performing walkdowns, and evaluating characterization data, including survey data for radiological and chemical hazards.
  • Removed facility equipment, utility service components, tanks, sumps, asbestos, low‐level waste, and PCB-contaminated items.
  • Removed, decontaminated, packaged, shipped, and transferred 13 breached fluorine cells stored in Building C‐0752‐A.
  • Characterized, removed, sorted and segregated, packaged, transported, and disposed of the building contents and structures of inactive facilities (C‐402 Limehouse, C‐405 Incinerator, C‐746A West End Smelter).
  • Characterized the concentrations and distribution of uranium compounds, Pu‐239, Cs‐137, and other radionuclides, PCBs, lead, mercury, and other metals.

Groundwater Site Assessment – Portage completed Site Investigation and code analysis activities for the landfills, the Southwest Plume, and the burial grounds. The Site Investigation and associated regulatory documentation were being completed for the landfills to determine if upgradient sources of groundwater contamination are influencing the contamination observed in the landfill monitoring wells.


Plume Containment – Portage’s involvement in the plume containment project included two basic components: 1) operation and management of the existing systems in accordance with the interim Northeast and Northwest Plume Records of Decision, and 2) support to DOE in obtaining regulatory approval for an environmental remedy, thereby allowing the shutdown of the pump-and-treat system in a timely manner. Portage sampled and monitored plumes, analyzed data, and evaluated the effectiveness of the remediation approach. Value engineering analysis and detailed cost estimates were developed in support of the remedy.
