The US Department of Energy’s National Nuclear Security Administration (NNSA) has begun construction of a new nuclear monitoring facility at Oak Ridge National Laboratory in Tennessee.
The project is designed to strengthen the country’s ability to monitor nuclear activities and respond to emerging security threats.
Officials marked the beginning of construction during a ceremony attended by NNSA Administrator Brandon Williams, Representative Chuck Fleischmann, and Oak Ridge National Laboratory Director Stephen Streiffer.
The new facility is called the Advanced Testbed and Operations Learning Laboratory(ATOLL). It will cover about 21,000 square feet and serve as a center for nuclear monitoring, research, and workforce training. Construction is expected to be completed in 2028.
ATOLL to Support Nuclear Monitoring
ATOLL will bring together scientists, engineers, and security experts working on nuclear nonproliferation programs. One of its main roles will be monitoring foreign activities related to weapons-grade uranium enrichment.
Uranium enrichment is a process that increases the concentration of uranium isotopes and can be used for both civilian nuclear energy and nuclear weapons development.

The facility will also help train specialists in nuclear detection and analysis. These experts study nuclear materials, identify potential threats, and support efforts to prevent the spread of nuclear weapons. ATOLL will provide space for testing and evaluating advanced technologies used in these missions.
US Nuclear Security Strategy
The new center will operate under the NNSA’s Nonproliferation Stewardship Program. This program supports the development of the technical infrastructure and skilled personnel needed to address nuclear security challenges worldwide. It also helps maintain expertise in nuclear science and monitoring technologies.
Officials say understanding how nuclear programs operate is essential for detecting and preventing potential threats.
During the groundbreaking ceremony, Williams said that deep knowledge of atomic science and weapons production helps the US deter adversaries and strengthen national security. He added that the investment in ATOLL will expand the agency’s ability to understand nuclear weapons programs and related technologies.

Why the Project Matters
Global concerns about nuclear proliferation have increased as several nations continue expanding nuclear capabilities and enrichment programs. Reliable monitoring systems and trained experts play a key role in verifying activities and identifying potential risks. Facilities such as ATOLL help provide the technical foundation needed for these efforts.
Oak Ridge National Laboratory has long been a major center for nuclear research in the US. The addition of ATOLL will expand its role in national security and nuclear monitoring.
Once completed, the facility is expected to strengthen America’s ability to detect nuclear threats, support international nonproliferation efforts, and prepare the next generation of nuclear security specialists.
