BLUF: Savannah River Nuclear Solutions LLC holds a $27,583,176,865 Department of Energy (DOE) contract to manage and operate the Savannah River Site in Aiken, South Carolina, with performance running through September 30, 2027.

The contract, numbered DE-AC09-08SR22470, was signed January 10, 2008, and is administered by DOE's National Nuclear Security Administration MO Contracting office. Savannah River Nuclear Solutions LLC is a subsidiary of Fluor Corporation, according to USAspending.gov recipient records. The award is classified as a definitive contract.

Why it matters: Management-and-operating (M&O) contracts for DOE's national laboratory and nuclear site network are among the largest single obligations in the federal contracting universe, and the Savannah River Site award ranks among the highest-value M&O contracts government-wide. These long-duration awards give the prime contractor — and its parent — sustained visibility into DOE site operations budgets and subcontracting opportunities across the site's mission areas for years at a time. Contractors tracking DOE nuclear security and environmental management spending should treat M&O primes like Savannah River Nuclear Solutions as long-term teaming and subcontracting targets rather than one-time award opportunities.

• Total obligated value: $27,583,176,865
• Contract number: DE-AC09-08SR22470
• Period of performance: January 10, 2008 – September 30, 2027
