Hanford Tank Waste Operations & Closure (H2C)

What Hanford Tank Waste Operations & Closure (H2C) does

Hanford Tank Waste Operations & Closure (H2C) is a privately held limited liability company formed as a joint venture of BWX Technologies (BWXT), Amentum, and Fluor to serve as the prime contractor for the U.S. Department of Energy's tank waste management at the Hanford Site in Richland, Washington. The company commenced tank operations in February 2025 and manages 177 underground waste storage tanks (149 single-shell tanks and 28 double-shell tanks) holding 56 million gallons of radioactive and chemical waste left over from Cold War-era plutonium production. H2C's mission is to safely remove, treat, and dispose of this waste inventory and ultimately close the legacy tank farms, addressing what the DOE characterizes as the nation's largest and most complex environmental cleanup.

H2C's core service portfolio comprises three operational pillars: Tank Farms Operations (physical management of the 177 underground storage tanks organized into 18 farm groups), the Direct-Feed Low-Activity Waste (DFLAW) program (which separates high-activity from low-activity waste and feeds the latter to the Waste Treatment and Immobilization Plant for vitrification into stable glass), and eventual operations of portions of the WTP. Supporting these are proprietary operational technologies including a cold spray metal coating system for extending tank service life and an innovative tank dome access system enabling waste retrieval from single-shell tanks without full decommissioning. The company is also constructing a seven-mile pipeline connecting the SY Farm in the 200 West Area to the 200 East Area to expand site-wide waste transfer capability.

H2C generates revenue exclusively through a managed-services contract with the U.S. Department of Energy, funded by federal appropriations for environmental remediation. The company operates a direct enterprise/government sales motion with no commercial distribution channels, serves a single customer (the DOE) under a single primary contract, and pursues operational excellence through an ISO 14001 certified Environmental Management System. As a joint venture, H2C benefits from the combined nuclear operations, radioactive waste management, and DOE regulatory expertise of its three parents, supplemented by four teaming subcontractors providing safety systems, simulation and data capabilities, mission assurance, and environmental integration support.

Core offering

H2C safely removes, treats, and disposes of 56 million gallons of radioactive and chemical waste held in 177 underground storage tanks at the U.S. Department of Energy's Hanford Site in Washington State. The company operates the Tank Farms, runs the Direct-Feed Low-Activity Waste (DFLAW) vitrification program feeding the Waste Treatment and Immobilization Plant, and will eventually operate portions of that plant to provide final treatment and disposal of Hanford tank waste.

Product overview

Hanford Tank Waste Operations & Closure (H2C) is a joint venture providing environmental remediation and waste management services, not a traditional product company. The company's service portfolio centers on safely removing, treating, and disposing of radioactive tank waste at the Hanford Site. Core services include Tank Farms Operations (managing 177 underground storage tanks holding 56 million gallons of waste), the Direct-Feed Low-Activity Waste (DFLAW) program for waste treatment, and future Waste Treatment and Immobilization Plant operations. Supporting these are innovative technologies for tank waste retrieval and infrastructure reinforcement. H2C officially began tank operations at Hanford in February 2025 as a contractor for the U.S. Department of Energy.

Expansion highlights5 records

Direct peers

• Savannah River Mission Completion: Liquid waste contractor at the DOE Savannah River Site, performing tank waste retrieval, treatment, and disposition under a similar scope to H2C's Hanford mission. Directly comparable mission, customer (DOE Office of Environmental Management), and risk profile.
• Navarro Research & Engineering: DOE-focused contractor delivering environmental remediation, nuclear operations, and technical services across multiple DOE sites. Comparable federal contracting model and overlapping nuclear/environmental mission set.
• Mission Support Alliance: Hanford Site-wide services contractor providing site infrastructure, utilities, and operational support across the same physical site as H2C. Same customer (DOE Hanford Field Office) and same site footprint with adjacent mission responsibilities.
• Nuclear Waste Partnership: Manages the Waste Isolation Pilot Plant (WIPP), the U.S.'s only operating deep geological repository for transuranic radioactive waste. Same DOE customer (Office of Environmental Management), same high-hazard radioactive waste mission, comparable multi-decade contract structure.
• Bechtel National: Operates portions of the Waste Treatment and Immobilization Plant (WTP) at Hanford — the facility H2C plans to operate for final waste vitrification. Sister-site mission with same customer and overlapping technical scope.

Regional players

• Battelle Memorial Institute: Operates Pacific Northwest National Laboratory (PNNL) on the Hanford Site, managing DOE science and national security missions from the same physical site as H2C. Shares the Hanford regulatory environment and DOE customer but operates a fundamentally different scientific-research mission.

Broad incumbents

• Science Applications International Corporation (SAIC): Large federal services and IT contractor with a meaningful DOE Environmental Management and nuclear security portfolio. Comparable federal contracting scale and customer set, but mission scope is much broader than H2C's focused tank waste operations.
• Tetra Tech: Global consulting and engineering firm with deep federal environmental and water practices, including DOE and DoD cleanup work. Adjacent mission in environmental consulting/remediation but serving a much broader customer base.
• AECOM: Major government services and infrastructure firm with significant DOE, DoD, and environmental remediation work. Competes for adjacent federal environmental management scopes but does not specialize in tank waste operations.
• Parsons Corporation: Large federal services contractor with a substantial DOE Environmental Management and nuclear security portfolio. Overlaps H2C's mission in environmental remediation and federal hazardous-waste work but as part of a much broader portfolio.
