Ensuring the future of America's nuclear security mission

The Uranium Processing Facility (UPF) is being built at the Y-12 National Security Complex by Consolidated Nuclear Security, a limited liability company of which Bechtel is a majority partner.  The facility will be a multi-building, state of the art complex for enriched uranium operations related to nuclear security.  It will not only ensure the long-term viability, safety, and security of the enriched uranium capability in the U.S. but also support the nation’s nuclear weapons stockpile, the downblending of uranium to prevent the spread of nuclear weapons, and provide uranium for fuel for U.S. Navy submarines and aircraft carriers.  Currently, these unique capabilities reside in aging World War II and Cold War-era buildings that are inefficient and costly to operate and maintain. 

At an estimated $6.5 billion, UPF is one of the Department of Energy’s largest investments in Tennessee since the Manhattan Project and one of the National Nuclear Security Administration’s largest construction projects. Modern safety standards, security and flexibility are key design attributes.  Once UPF is in full operations, the U.S. will reap the benefits of a new uranium processing facility and significantly lower operating and maintenance costs.

UPF achieves seven million safe working hours

UPF achieved another significant safety milestone recently: seven million working hours without a lost time incident. The Project’s last lost time injury was more than three years ago in January 2014.  

“Achieving seven million hours without a lost time incident is a safety accomplishment, but it’s really about people,” said UPF Project Director Brian Reilly. “It’s about people making safety a core value, people being vigilant for themselves and their colleagues, and people working together to build and maintain a strong safety culture.”


UPF begins placing mass fill concrete

The construction of the Uranium Processing Facility (UPF) reached another major milestone in May of 2017 when concrete placement began for the fill upon which the facility’s foundation will be built. 

This part of the project, called mass fill, is expected to last 11 months. About 132,000 cubic yards of concrete and 42,000 cubic yards of engineered backfill will be placed as part of mass fill. This work requires 210 concrete placements in nine lifts, and each lift is three feet deep. 

“Placing the concrete for the mass fill is a significant achievement,” said UPF Project Director Brian Reilly. “We have a strong team that has been able to keep the work on schedule while ensuring worker safety.” 

Mass fill was preceded by mass excavation, which removed more than 300,000 cubic yards of soil from the site.

All of the concrete for mass fill is being provided by UPF’s onsite concrete batch plant, which was installed in 2016.
