DUF6 Conversion Facilities Operations & Maintenance
DOE awarded Mid-America Conversion Services, LLC (MCS) — a joint venture led by Atkins with Westinghouse and Fluor Federal Services — the DUF6 conversion-facility operations & maintenance contract for Paducah, KY and Portsmouth, OH: $318,811,847 over a five-year period of performance, awarded September 29, 2016.
Awarded 2016-09-29 as a five-year, $318,811,847 base contract, this operates DUF6 conversion facilities at Paducah, Kentucky and Portsmouth (Piketon), Ohio, converting DOE's roughly 700,000-metric-ton depleted-uranium-hexafluoride inventory into depleted uranium oxide (reuse/disposal) and aqueous hydrofluoric acid (sold for industrial use), plus maintaining specialized cylinder-storage yards at both sites. Modifications and options have since raised the potential ceiling to $1,076,238,217.60 and extended the period of performance to September 30, 2025 (per USASpending.gov); DOE ultimately re-competed the work as part of a larger Portsmouth Paducah Project Office Operations and Site Mission Support contract, awarded November 8, 2024 to a different joint venture (Atkins, Westinghouse, and Jacobs — not including Fluor).
