Amentum Team Awarded $21B Savannah River Site Integrated Mission Completion Contract; CEO John Vollmer Quoted

Amentum, a leading contractor of the Department of Energy (DOE), announced on Thursday that Savannah River Mission Completion (SRMC), a joint venture team comprised of Amentum, BWXT Technical Services Group, Fluor Federal Services, DBD and Wesworks, has been awarded a potential ten-year, $21 billion single-award Master Indefinite Delivery Indefinite Quantity (IDIQ) contract.

“We are pleased to have been awarded this contract. Amentum and our heritage companies have a long history of supporting the DOE’s environmental management programs and have managed numerous projects at the Savannah River Site,” said John Vollmer, CEO of Amentum and a six-time Wash100 Award recipient.

SRMC will be responsible for liquid waste operations, the closure of waste tanks, the operation of the Savannah River Site’s Defense Waste Processing Facility, the Salt Waste Processing Facility and associated production and disposal facilities.

“We look forward to working with our DOE client, partners, regulators, and community stakeholders to further advance the Department of Energy’s mission of safe cleanup of legacy liquid waste at the Savannah River Site,” Vollmer added.

The Savannah River Site is 310 square miles located near Aiken, S.C. on the Savannah River bordering South Carolina and Georgia.

“Amentum and our partners have a tremendous track record treating waste and managing nuclear operations around the DOE complex,” said Mark Whitney, president of Amentum’s Nuclear & Environment Business Unit. “We are honored to be a part of this team and begin operations under this new contract”.

This announcement comes only a day after the company announced that United Cleanup Oak Ridge (UCOR), a joint venture among Amentum, Jacobs and Honeywell, was awarded a ten-year, $8.3 billion IDIQ Oak Ridge Reservation Cleanup contract.
