U.S. Nuclear Security Enterprise

A Bechtel-led partnership began managing and operating Pantex and Y-12 for the U.S. Department of Energy's National Nuclear Security Administration in July 2014.

The role of the Bechtel-led Consolidated Nuclear Services (CNS) is to improve performance at both facilities while ensuring an uncompromising focus on safety, security, quality, and cost-effectiveness. CNS will do that with shared business systems and other efficiencies, with innovation, and by applying lessons learned.

Bechtel's partners in Consolidated Nuclear Security, LLC are Lockheed Martin Services, Inc., ATK Launch Systems Inc., and SOC LLC. Booz Allen Hamilton, Inc. is a teaming subcontractor.

Pantex and Y-12 play key roles maintaining the safety, security, and effectiveness of the U.S. nuclear weapons stockpile, missions vital to national and global security.

Y‑12 was the first site in the world to electromagnetically separate uranium on an industrial scale, but that was only the beginning. Since then, the complex has amassed a wealth of uranium know-how:

  • Machining, recycling, and reprocessing
  • Securing and storing
  • Handling and transporting
  • Analyzing and detecting
  • Training others to safeguard uranium


For decades, Pantex has provided technology for the manufacturing, evaluation, and testing of nuclear explosives, joint test beds, and other special nuclear materials. This experience uniquely qualifies Pantex scientists and engineers to provide technology solutions for a variety of problems. Pantex has organizations dedicated to computerized special tooling, test equipment (including critical nuclear explosive testers), packaging, and system engineering. Pantex is also responsible for:

  • Carrying out nuclear weapons life-extension programs
  • Dismantling and disposing of retired weapons systems
  • Surveilling active weapons systems
  • Developing, testing, and fabricating high-explosives components
  • Storing and surveilling plutonium pits, the cores at the heart of thermonuclear weapons


Since 1994, the site has been involved in 16 international missions to recover nuclear materials, most recent in France, Italy, and Canada in 2013 and Belgium and South Korea in 2014. The team at Y-12 are responsible for:

  • Safely and securely storing uranium
  • Processing and manufacturing special materials vital to national security
  • Supplying highly enriched uranium for U.S. Navy nuclear-powered aircraft carriers and submarines (the very vessels whose power plants derive from the Bettis and Knolls atomic laboratories that Bechtel manages for NNSA and the U.S. Navy) 
  • Conducting tests and training as well as decommissions weapons to help prevent the spread of weapons of mass destruction

A period of transition

During the contractor transition, between March and June 2014, our team—on schedule and under budget: 

  • Established the structure and processes to manage the two sites as one enterprise
  • Completed more than 3,000 schedule actions
  • Onboarded 7,800 employees
  • Inspected more than 400 facilities
  • Reviewed and approved more than 5,000 procedures
  • Consulted with dozens of community leaders and elected officials

The contract unites the two sites—more than 1,100 miles (nearly 1,800 kilometers) apart—under a new, consolidated company.

A new structure planned for Y-12

The new Uranium Processing Facility (UPF) is in its preliminary design phase. When complete, the $6.5 billion facility—the largest construction project in Tennessee history—will house enriched uranium operations, including assembly, disassembly, quality evaluation, metalworking, and product certification.

UPF will replace several aging facilities at the Y-12 complex—using less space and benefiting from improved security and technologies.

We are ready to build on the proud traditions of Pantex and Y-12 and improve the performance and sustainability of these sites with our customer, NNSA, as well as our employees.—Jim Haynes, CNS president and senior Bechtel executive
