History
Early in the 2010s, the Department of Energy issued a tender for the combined management of the Y-12 and Pantex facilities on a ten-year contract. CNS won this contract and began management of the two facilities in 2014. The contract was worth approximately $2 billion a year.

In 2020, the Department of Energy announced that they would not be exercising the additional options in Consolidated Nuclear Security's contract, which was set to expire on Sept. 30, 2021, three years before the end of the ten-year contract. The Department of Energy terminated the contract for failing to meet performance standards. The situation was made trickier because Bechtel is building the Uranium Processing Facility at Y-12 as a subcontractor to CNS. The primary issues that led to the contract cancellation were repeated failures to meet safety and security standards, with criticality safety and cyber security, being particular concerns.
