NAC International Inc.

NAC International Inc., a foreign-owned nuclear fuel cycle consulting and specialized transportation services company headquartered in Peachtree Corners, Georgia, operates as a prime contractor (98% of recent awards) delivering radioactive materials handling, nuclear fuel transportation, and site remediation services to the Department of Energy and related federal agencies on a full-and-open basis with no set-aside designations. The vendor is a subsidiary of Hitz Holdings USA Inc. and operates alongside sibling subsidiaries NAC Philotechnics LTD., NAC LPT LLC, and Niagara Energy Products.

NAC International's capability portfolio centers on specialized nuclear materials transportation, packaging system design and certification, radioactive fuel handling, and hazardous operations support — services grounded in deep expertise with Department of Transportation, Nuclear Regulatory Commission, and Department of Energy compliance requirements. Representative prime work includes a $20.9 million firm fixed-price definitive contract from the National Nuclear Security Administration (awarded June 2023, performing through June 2028) for transportation services, escort services, and technical support related to shipments of irradiated Tritium Producing Burnable Absorber Rods to the Savannah River Site Tritium Extraction Facility; a $1.84 million purchase order from the Office of the Secretary of Defense (March 2022, extending through November 2025) for tristructural isotropic fuel transportation support and fuel package design and fabrication under Project PELE; and a $945,600 firm fixed-price definitive contract from the Department of Agriculture (September 2023, completing June 2027) for removal and site preparation of an irradiator at the Eastern Regional Research Center. NAC International also holds two cooperative agreements under the Department of Energy's Nuclear Energy Research, Development and Demonstration program (CFDA 81.121): a $3.34 million award (June 2026 through May 2029) to design, test, and obtain NRC certification of a High-Assay Low-Enriched Uranium transportation packaging system for Small Modular Reactor operators, and a $1.99 million award (June 2026 through May 2028) to design and obtain revised NRC certification for a modified OPTIMUS-L transportation packaging system for HALEU in multiple forms.

Customer concentration is heavily anchored to the Department of Energy ecosystem. The top five customer organizations account for 64% of awards by count, with the Department of Energy Savannah River National Laboratory leading by both count (13 awards) and potential value ($134.2 million combined), followed by the National Nuclear Security Administration (11 awards, $31.9 million), the Department of Energy Office of Environmental Management ($24.8 million across two awards), the broader Department of Energy portfolio (29 awards, $12.2 million), and the National Institute of Standards and Technology (6 awards, $2.2 million). The Savannah River and NNSA rankings diverge sharply between volume and dollars — Savannah River dominates on both dimensions — underscoring that NAC International's largest-dollar relationships are concentrated in a narrow customer set tied to tritium extraction, nuclear fuel supply chain, and advanced reactor development missions.

NAC International places task orders under four named Indefinite Delivery Contracts: DEAM0903SR22214 (19 task orders, $11.6 million combined value), DEAM0997SR18563 (15 task orders, $14.9 million combined value), DENE0000072 (6 task orders, $2.7 million combined value), and 89303320DEM000030 (1 task order). These vehicles support Department of Energy operations and remediation activities. Award volume has been sparse in recent years — one award in 2020, two in 2022, two in 2023, two in 2025, and two in 2026 — with a combined recompete exposure of $21.8 million across three awards completing within the next twenty-four months. NAC International operates as a sub on a limited basis: two sub-contract awards appear in the source, including a sub to Triad National Security LLC on the Los Alamos National Laboratory management and operations competition (September 2025) and a sub to Central Plateau Cleanup Company LLC on the Hanford Central Plateau Cleanup Contract (January 2025 modification valued at $61.6 million incremental funding). The Service Contract Inventory dataset, which captures federal service contracts above $150,000, shows minimal activity — 5 SCI records spanning FY2022–FY2024 with zero invoiced SCI revenue and 0.8 FTEs reported in FY2024 — indicating that NAC International's federal footprint is dominated by goods and specialized transportation services rather than labor-hour-based service contracts subject to SCI reporting.

NAC International's principal NAICS categories are Other Scientific and Technical Consulting Services (22 awards), Remediation Services (9 awards), and Specialized Freight Trucking Long-Distance (5 awards), with PSC coding reflecting Transportation/Travel/Relocation services (41 awards) and Specialized Test and Handling Equipment for Nuclear Ordnance (11 awards). The vendor's long award history — first recorded award in 1987 — and technical depth position it as a specialized incumbent in the nuclear fuel supply chain and Savannah River operations ecosystem, with limited subcontracting footprint and minimal exposure to competitive set-asides or small-business vehicles.
