Amentum-led Central Plateau Cleanup Company won 96% of its potential overall fee, $18.6 million out of a potential $19.3 million, for its remediation at the Department of Energy’s Hanford Site in Washington state.
All five Hanford contractors that had fee scorecards released Tuesday have cost-plus contracts that allows them to make a profit on top of their fixed costs. The contractors received scorecards mostly for work during fiscal 2025 took home at least 90% of their potential fee.
Central Plateau Cleanup claimed 93% or roughly $8.9 million out of $9.6 million of its subjectively-rated fee, the DOE Office of Environmental Management said in a fee scorecard publicly released Dec. 23. The fiscal 2025 review period ran from Oct. 1, 2024, through Sept. 30 of this year.
The fee scorecards are based on two main criteria, the contractor’s record on achieving objective, recorded goals and secondly on subjective ratings determined by the DOE nuclear cleanup office.
Fluor and Atkins are also part of Central Plateau Cleanup. The $10-billion Central Plateau contract started in December 2019 and runs until December 2029.
Radiological controls at the Central Waste Complex as well as software program requirements are areas that Central Plateau Cleanup should improve upon, according to the fee scorecard.
Key achievements by Central Plateau Cleanup include getting the Integrated Disposal Facility ready to receive containers of low-activity tank waste solidified in glass from the Waste Treatment and Immobilization Plant (WTP). The cleanup contractor also prepared the Capsule Storage Area to receive dry storage casks containing radioactive capsules from the Waste Encapsulation Storage Facility, according to the review.
BWXT-led Hanford Tank Waste Operations & Closure (H2C) the new tank waste contractor at the former plutonium production site took home 94% or $26.3 million out of a potential $28.1 million for its first seven months on the job.
The fee scorecard is for the period extending from Feb. 24 through Sept. 30, 2025. The review period ended just before Hanford started converting some of the less-radioactive tank waste into glass form at the WTP’s Direct-Feed-Low-Activity Waste Facilities.
In addition to finishing waste retrieval of single-shell tank A-101, H2C also completed the shipment of 2,000 gallons of radioactive sludge out of state for grouting and disposal as part of the test bed initiative offsite, according to the scorecard.
H2C consists of partners BWXT, Amentum and Fluor. The H2C contract, which started in February 2024 and runs through February 2034, has a contract ceiling of up to $45-billion. H2C started work at the site in early 2025 following a lengthy contract challenge. The H2C scorecard runs from late February 2025 through Sept. 30, 2025.
H2C succeeded Amentum-led Washington River Protection Solutions (WRPS). WRPS garnered 90% of its potential fee award for its last final five months on the job.
The WRPS scorecard showed the joint venture winning 90% of its potential fee or $17.2 million out of a potential $19.2 million. That is for the time period running from Oct. 1, 2024 through Feb. 23, 2025.
By contrast, WRPS took home only 69% of its fiscal 2024 fee, according to the fee scorecard for fiscal 2024. The 2024 fee scorecard showed WRPS earning $32.8 million out of a potential $47.5 million.
Leidos-led Hanford Mission Integration Solutions (HMIS), the landlord contractor in charge of roads, grounds and infrastructure, did well. It won $21.9 million out of a potential $23 million, or 91% in fiscal 2025, according to the scorecard.
HMIS completed construction of the 200 West Area potable water tank and the Central Plateau Water Treatment Plant but still needs more effective oversight of subcontractors, DOE said.
The HMIS contract, currently valued at $5.3 billion, began in August 2020 and is currently scheduled to run through August 2028.
Finally, Navarro-ATL (formerly known as Hanford Laboratory Management and Integration), which manages the 222-S Laboratory, won 95% of its potential fee. That amounts to more than $5 million out of a potential $5.3 million, according to the scorecard for fiscal 2025.
The 222-S lab analyzes highly-radioactive samples of waste from Hanford’s underground tanks. DOE lauded the Navarro-ATL team for coming up with a new method resulting in less hazard to the laboratory workers. The contractor does need to work on Implementation of analytical services quality assurance requirements, DOE said.
The Navarro-ATL contract, valued at more than $636 million, began in January 2021 and was scheduled to expire in January 2026. However, the contractor team recently received a one-year extension from DOE.
As of early Dec. 24, DOE had not issued a fiscal 2025 scorecard on its website for Bechtel National at Hanford.
