The US Department of Energy (DOE) has chosen Southern Ohio Cleanup Company, a joint venture led by Amentum in partnership with Fluor Corporation and Cavendish Nuclear USA, for the Portsmouth Gaseous Diffusion Plant Decontamination and Decommissioning Contract.

This $5.87 billion contract covers a 10-year period, with potential extensions for tasks orders up to an additional five years. The joint venture’s responsibilities will encompass the demolition and disposal of facilities, process equipment, process buildings, and other facilities, as well as remediation of contaminated soils and groundwater, and uranium material disposition.

The DOE Portsmouth site, located in southern Ohio, is a 3,700-acre federal reservation established in the early 1950s. This former piece of the nation’s nuclear weapons complex was operational from 1954 until 2001, producing enriched uranium. Fluor-BWXT Portsmouth, LLC has managed the decontamination and decommissioning work at this site since March 2011.

“Fluor and our partners have an unsurpassed performance record of delivering on important decontamination and decommissioning work across the Department of Energy complex,” said Tom D’Agostino, president of Fluor’s Mission Solutions business. “We have worked at the Portsmouth site and have been involved in the community for the past 12 years—we know the importance of staying local. We are proud that this contract includes local small business partners who are committed to building an environmentally and economically sustainable future for southern Ohio. We look forward to maintaining our momentum and working collaboratively with the DOE, regulators, stakeholders, and the community.”
