About the company
Consolidated Nuclear Security, LLC operates as a management-and-operations (M&O) contractor for Department of Energy National Nuclear Security Administration (NNSA) nuclear weapons production and security facilities, serving primarily in a subcontractor role under Department of Energy and Department of the Air Force prime awards. The vendor is structured as a for-profit limited liability company based in Oak Ridge, Tennessee, with a heavy concentration in facilities support services (5 of 6 awards) spanning nuclear weapons production, tritium operations, and national security complex management.
The vendor's award footprint is dominated by two massive NNSA M&O contracts. The largest is an indefinite-delivery/indefinite-quantity contract for integrated management and operation of the Y-12 National Security Complex in Oak Ridge, Pantex Plant in Amarillo, and Savannah River Tritium Operations, with a combined potential value of $53.51 billion and $34.35 billion obligated to date (64% of potential value). The second is an analytical services sub-award under Contract 89233224CNA000004 for Pantex Plant operations, placed by Pantexas Deterrence, LLC as prime. Recent sub-awards span analytical services at Pantex (October 2025, November 2024) and participation in the integrated Y-12/Pantex/Savannah River M&O contract as of May 2026.
Customer concentration is acute. The Department of Energy National Nuclear Security Administration accounts for the full $53.51 billion in potential value across two awards, representing 100% of meaningful financial exposure. The Department of the Air Force holds three awards with no disclosed dollar value, and the General Services Administration holds one award at $6 thousand. Recompete exposure is singular and massive: the $53.51 billion integrated NNSA M&O contract reaches ultimate completion within the next twenty-four months, creating a one-time, high-stakes recompete for the entire vendor footprint. The vendor's operating posture is non-competitive set-aside work; all identified awards are direct awards or sub-awards on management-and-operations contracts rather than open competition.
