Uranium Processing Facility marks construction milestone with “topping off”

The Uranium Processing Facility (UPF) at the Y-12 National Security Complex in Oak Ridge, Tennessee, achieved another construction milestone in February - 'topping off' the final piece of structural frame on the Mechanical Electrical Building (MEB).

Crews began erecting structural steel for the 66,000-square-foot MEB in July 2018. About 1,200 tons of steel were used to complete the structure. The building will house most of the mechanical and electrical utility equipment required for UPF.

'This takes us one step closer to our goal of a modern, more efficient, and safer facility for conducting highly enriched uranium processing operations,' said Dale Christenson, UPF Project Office Director.

UPF is being built through a series of seven subprojects. Two have been completed to date and both are on time and under budget.

The MEB is the first of UPF's buildings to go vertical. With the steel framework complete, contractors will next install the roof and walls. Contractors expect that to be completed by early summer.

Using a 'build to budget' strategy, NNSA has committed to Congress to deliver UPF for no more than $6.5 billion by the end of 2025, assuming stable funding through the duration of the project.
