A federal cleanup contractor in Oak Ridge is removing exterior panels known as transite panels from the last part of the K-25 Building that is still standing.

K-25 was built to enrich uranium for atomic bombs during World War II and was once the world’s largest building under one roof. It’s been unused for decades and is being torn down.

Most of the mile-long former gaseous diffusion building, located at East Tennessee Technology Park, has been demolished. About two million square feet of the U-shaped building have been removed, according to a Thursday press release from UCOR, the cleanup contractor for the U.S. Department of Energy in Oak Ridge.

The pre-qualification window for companies to bid on the professional site design for a museum at the East Tennessee Technology Park closed in February. Eight firms that specialize in museum planning and exhibit design responded to the pre-qualification request.

Planning for the museum is one of several activities under way to commemorate ETTP’s history, including a history center located on the second floor of the Oak Ridge Fire Station and an observation tower overlooking the K-25 Building footprint.

The museum will house artifact and historic materials removed from the K-25 Building, which was built during World War II as part of the top-secret Manhattan Project, a federal program to build the world’s first atomic weapons. The building and ETTP, often referred to as the K-25 site, were also used to enrich uranium after the war.

UCOR has removed the highest-risk components remaining in the K-27 building at East Tennessee Technology Park, a press release said.

Six components known as NaF, or sodium fluoride, traps have been removed by crane, the press release said.

The K-27 building is a “sister” to the mile-long K-25 gaseous diffusion process building, which is now nearly demolished, the release said. Both are Manhattan Project buildings built to produce materials for nuclear weapons. As work is completed at K-25, crews are shifting to K-27.

Mark Ferri, who has led the safe, successful deactivation and demolition work at K-25 since UCOR arrived in Oak Ridge in August 2011, has announced that he will retire from the company at the end of February and will accept a CH2M Hill corporate opportunity in the United Kingdom.

Ferri was part of UCOR’s original, handpicked leadership team. His selection proved a wise one, as progress under his leadership has been stellar. Workers have demolished more than two million square feet of the old gaseous diffusion facility, and more than 15,000 loads of waste have been shipped under the “pack as you go” philosophy that he and his counterpart, Waste Management Manager Jeff Bradford, installed as part of the UCOR way of doing business.

McKinney said the employees, who worked for subcontractors, were notified of the layoffs Thursday. He said it’s part of the normal ebb and flow of subcontracting.
