Portsmouth Gaseous Diffusion Plant Decontamination & Decommissioning
DOE selected Southern Ohio Cleanup Company, LLC for the Portsmouth GDP D&D contract — a joint venture led by Amentum with Fluor and Cavendish Nuclear USA — with an estimated value of $5.87B over a 10-year ordering period and task orders up to an additional five years. Fluor is a partner, not the lead, on this team.
Decontamination and decommissioning of the Portsmouth Gaseous Diffusion Plant near Piketon, Ohio — built in the early 1950s to produce enriched uranium for the U.S. nuclear weapons complex and, later, commercial reactors, until it ceased enrichment operations in 2001 — requires demolition and disposal of process buildings, equipment, and ancillary facilities, along with remediation of contaminated soils and groundwater and disposition of remaining uranium material. It replaces the prior PORTS D&D contract held by Fluor-BWXT Portsmouth, LLC, with site-operations functions (utilities, security, uranium transfers, nuclear-material control/accountability) split off into a separate DOE support contract so SOCCo could focus solely on decommissioning.
