A decade after military planners began its design, the largest construction project in Tennessee is starting over with a new and different layout.
The Department of Energy’s Uranium Processing Facility in Oak Ridge has been revamped to help reduce its escalating costs by more than a third.
But the head of the federal agency building the proposed $6.5 billion complex said Thursday the project is still needed to upgrade the aging Y-12 weapons plant and the project should still spur business across the Tennessee Valley as it is built in the next decade.
Retired Lt. Gen. Frank Klotz, a Department of Energy undersecretary who heads the National Nuclear Security Administration, said one part of the Oak Ridge facility, Building 9212, is more than 60 years old.
“There are a lot of concerns about the safety and functionality of structures that old,” Klotz said after visiting Y-12 this week.
