The U.S. Department of Energy (DOE) announced on Friday the award of a contract to Portsmouth Mission Alliance, LLC of Idaho Falls, Idaho, for the performance of infrastructure support services at the Portsmouth Gaseous Diffusion Plant near Piketon.

The value of the contract is $122.8 million, with a full potential value of $139.7 million including the total maximum value of services under the indefinite delivery/indefinite quantity contract line items.

The base period of performance is three years with an additional 22-month option period. Seven proposals were received in response to the solicitation.

In an effort to align contractor and taxpayer interests, The DOE says the contract includes firm-fixed-price, labor hour, cost reimbursement, and indefinite delivery/indefinite quantity contract line items.

The primarily firm-fixed-price nature of the contract will allow DOE to hold the contractor accountable for meeting the contract requirements.

Infrastructure support services to be provided under the contract include surveillance, maintenance and repair of facilities; janitorial services; grounds maintenance, snow removal, and pest control; roadway/parking lot maintenance; computing, telecommunication, and cyber security; fleet management; real and personal property management; records management and document control; safeguards and security; environment, safety, health and quality program; and training services.

The Portsmouth Gaseous Diffusion Plant (GDP) was constructed by the Atomic Energy Commission in the early 1950s for the purpose of enriching the fissile isotope of uranium from natural uranium to various product concentrations.

The facility, located in Piketon, was originally constructed and operated as a uranium enrichment plant to supply both highly enriched uranium (HEU) and low enriched uranium (LEU) for defense purposes and commercial nuclear fuel sales.
