The field work is complete on 27 cleanup projects at three federal sites in Oak Ridge that used $751 million in Recovery Act funds.

The U.S. Department of Energy’s Oak Ridge Office of Environmental Management, or EM, announced the end of the field work on Thursday.

“We’re done knocking down buildings and with all the work in the field,” said Mike Koentop, executive officer in Oak Ridge Office of Environmental Management. “We have paperwork left to do to close out projects.”

The American Recovery and Reinvestment Act of 2009, also known as the Recovery Act or stimulus bill, was passed by Congress and signed by President Barack Obama in February 2009. It was meant to help stimulate an economic recovery during the depths of the Great Recession, and it was intended to address long-neglected infrastructure projects and programs.

In Oak Ridge, the Recovery Act funding paid for several demolition projects such as the demolition of the 1.4-million-square-foot K-33 Building at the East Tennessee Technology Park and other projects ranging from mercury reduction at the Y-12 National Security Complex to transuranic waste processing at Oak Ridge National Laboratory.

Preparing the building for demolition, workers on Tuesday began removing transite paneling from the outside of the K-31 Building at East Tennessee Technology Park.

The former gaseous diffusion building, which is about 1.5 million square feet, was once used to produce enriched uranium for defense and commercial purposes. It was permanently shut down in 1987.

UCOR, a partnership between URS and CH2M Oak Ridge, is preparing the building for demolition, which is scheduled for later this year. Approximately 10,000 transite panels are expected to be removed during the next several months, a press release said. These panels are removed ahead of demolition because they contain asbestos and must be handled and treated with separate hazard abatement crews. [Read more…]

Demolition of the last standing section of the K-25 Building at the East Tennessee Technology Park is more than 75 percent complete.

UCOR workers began tearing down the last six units in the east wing of the mile-long Manhattan Project-era gaseous diffusion building in September. The majority of those six units—4.5 of them—are already on the ground, and work is continuing at a steady pace, the U.S. Department of Energy Oak Ridge Office reported in the December issue of Public Involvement News.

The entire project, including waste removal, should be completed next year, the Oak Ridge Office said.

The historic, U-shaped K-25 Building was erected to enrich uranium for atomic bombs during World War II, and it was once the world’s largest building under one roof. It once had 54 units. [Read more…]

K-25 East Wing Demolition

Demolition work began Tuesday on the last section of the historic K-25 Building, which was erected to enrich uranium for atomic bombs during World War II and was once the world’s largest building under one roof.

Most of the building, which is in west Oak Ridge, has already been demolished. Only a small section of the east wing remains at the former mile-long, U-shaped building.

K-25 was built during the top-secret Manhattan Project in World War II to enrich uranium for nuclear weapons through a process known as gaseous diffusion. Those operations ended in 1964. [Read more…]

The U.S. Department of Energy’s 2013 Oak Ridge facilities public bus tour begins June 3 and continues through Aug. 30. The tour offers visitors a first-hand look at the DOE’s Oak Ridge facilities and provides historical commentary on the transformation of the Oak Ridge Reservation during the past 70 years.

The reservation-wide tour is a popular destination for tourists visiting the area. Since its inception in 1996, the DOE public tour program has attracted more than 29,000 visitors from all 50 states. The three-hour tour allows visitors to see the reservation and learn historical facts and updates on the world-class missions under way in Oak Ridge. [Read more…]

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.

UCOR has shipped 15,000 loads of demolition debris from the K-25 Building at the East Tennessee Technology Park, the company announced last week.

The 15,000 loads represent approximately two million square feet of the deteriorated former gaseous diffusion building, built during World War II as part of the top-secret Manhattan Project. That square footage is the equivalent of 40 NFL football fields combined.

The material has been sent to the Environmental Management Waste Management Facility in Oak Ridge for permanent disposition.
