The SRS contract, valued at up to $21 billion over the contract period, was won by a joint venture led by a BWXT subsidiary and Fluor Corp. The team includes small businesses, DBD and Wesworks. Both Fluor and Amentum have existing waste management contracts at the site, but DOE did not indicate how the new contract would affect those.

DOE said it received four proposals, but did not identify submitters. Bechtel was believed to have been leading one competing team, according to industry publication Weapons Complex Monitor.

According to DOE, the contract includes high level waste vitrification, glass storage facility expansion, defense waste processing facility operations and potential management and stabilization of nuclear materials. Work will involve construction of the Savannah River Plutonium Processing Facility, set to come on line in 2030 and be built from the partially completed Mixed Oxide Fuel (MOX) plant.

At the agency's 35,000-acre Oak Ridge site near Knoxville, the estimated $8.3-billion new contract was awarded to a team that also includes Jacobs and Honeywell, with subcontractors RSI EnTec, Strata-G, Longenecker & Associates and Environmental Alternatives.

It replaces one awarded in 2011 to Jacobs as part of a joint venture of URS, now part of AECOM, and CH2M, which Jacobs acquired in 2018. That contract expires Jan. 31, 2022; but DOE has an option to extend it by six months.

DOE said it received four other proposals from bidders it did not identify.

The contract covers work at the Y-12 industrial area, Oak Ridge National Laboratory and East Tennessee Technology Park—all part of the Oak Ridge complex formerly the site of uranium processing for nuclear weapons. Activities are set to include cleanup of excess facilities at the laboratory and at Y-12; design, construction and operation of a new onsite disposal facility; and related site services for operating and closed facilities.

Teams at both sites will perform services through both fixed price and cost-plus task orders under their overarching IDIQ contracts.
