Two federal agencies have agreed to build a K-25 Viewing Platform at the historic site in west Oak Ridge that was used to enrich uranium for nuclear weapons and nuclear power plants during World War II and the Cold War. The design is expected to be complete in March and the building completed by the end of 2023.

The construction agreement for the viewing building at the former K-25 site was signed by the U.S. Department of Energy’s Oak Ridge Office of Environmental Management and U.S. Army Corps of Engineers.

The viewing platform will give visitors a view of the large 44-acre footprint of the former K-25 Building. K-25, which was the world’s largest building, was erected during World War II as part of the Manhattan Project to help enrich uranium for the world’s first atomic bombs during World War II. The K-25 Building was demolished in 2013, and many other structures at the site have been removed as the federal government turns over property for private development.

The K-25 Building site itself is now part of the Manhattan Project National Historical Park. That project commemorates the workers, equipment, and processes used during the Manhattan Project in Oak Ridge, Tennessee; Hanford, Washington; and Los Alamos, New Mexico.

The K-25 Viewing Platform and associated exhibits are the final components of a multi-project agreement that the Oak Ridge Office of Environmental Management signed in 2012, clearing the way for demolition of the North Tower of the mile-long, U-shaped K-25 Building. The projects commemorate the history of the K-25 site, which has also been known as the Oak Ridge Gaseous Diffusion Plant.

The Oak Ridge team that mostly cleaned up the former K-25 site, demolishing five large gaseous diffusion buildings and more than 500 structures, has received a Secretary’s Achievement Award from U.S. Energy Secretary Jennifer Granholm. The work was done ahead of schedule and under budget, the U.S. Department of Energy said.

Granholm honored the DOE Office of Environmental Management team from Oak Ridge in a virtual ceremony Wednesday, a press release said.

K-25 was used to enrich uranium for nuclear weapons and commercial nuclear power plants from World War II to the 1980s.

It was the first removal of a uranium enrichment complex, and it cleared 13 million square feet of deteriorated, contaminated structures from the site, the press release said.

“The Secretary’s Achievement Award honors a group or team of DOE employees and contractors who accomplish significant achievements on behalf of the department, demonstrating cooperation and teamwork in attaining their goals,” the press release said. “The award was given to the Oak Ridge Vision 2020 Project Team based on its achievements from 2020.”

The image above showing reindustrialization progress at East Tennessee Technology Park comes from a presentation on Oct. 11, 2017, by Dave Adler by the U.S. Department of Energy’s Oak Ridge Office of Environmental Management. The K-31/K-33 area is the blue area at the top right side of the ETTP site, and Duct Island is the purple/pink area just below it and slightly to the left. The former K-25 Building was in the yellow area at center. The proposed airport is at the bottom right in the blue and purple/pink area on the north side of State Route 58.

About 185 acres in the northwest corner of Heritage Center, the former K-25 site, have been transferred to the Community Reuse Organization of East Tennessee.

CROET is a nonprofit organization that helps find new uses for former U.S. Department of Energy property.

The 185 acres transferred to CROET at Heritage Center are where the K-31 and K-33 buildings used to be. The property transfer was recorded at the Roane County courthouse on October 10, said Lawrence Young, CROET president.

“We hope to be able to attract, over time, larger industrial clients,” Young said Monday.

The parcels are currently vacant, and they have been cleaned up by the U.S. Department of Energy and UCOR, DOE’s cleanup contractor in Oak Ridge. There should not be any impediments to using the parcels as industrial property from an environmental standpoint, Young said. [Read more…]

A celebratory event on Thursday will formally launch a project to commemorate the history of the former Oak Ridge Gaseous Diffusion Plant, a uranium-enrichment site that was once known as K-25 and built to help make the world’s first atomic weapons during World War II.

Thursday’s celebration will be followed by a public tour from 2 to 4 p.m.

Co-sponsored by the City of Oak Ridge, the event is part of the city’s 75th Anniversary celebration. It will feature a walk-through of the future home of the K-25 History Center, which will be located in the city’s Fire Station Number 4 at the East Tennessee Technology Park. The U.S. Department of Energy and URS|CH2M Oak Ridge LLC, or UCOR, DOE’s lead cleanup contractor, will unveil plans and the layout for the History Center before construction starts, a press release said.

Large graphics placed throughout the building will provide the visitor a preview of the finished center, the press release said. [Read more…]

Demolition work on K-27, last of big 5 uranium-enrichment buildings, to be complete this month

Demolition work started on K-27 in February.

Like the other four buildings that have already been demolished, the four-story, 383,000-square-foot K-27 building once used a process known as gaseous diffusion to enrich uranium.

The demolition is part of Vision 2016. That’s the plan by the U.S. Department of Energy Office of Environmental Management, or EM, to remove all five gaseous diffusion buildings from the site by the end of the year.

Federal officials said it’s the first time in the world that a uranium enrichment complex has been cleaned and removed. [Read more…]

DOE: Oak Ridge’s Building K-27 being torn down quickly

In February 2016, demolition crews started tearing down the K-27 gaseous diffusion building.

Now, only months later, the Oak Ridge Office of Environmental Management and its contractor UCOR have already completed demolition on more than 65 percent of the four-story, 383,000-square-foot facility, the U.S. Department of Energy said.

K-27 is the last of five large gaseous diffusion facilities to be torn down at the East Tennessee Technology Park, or ETTP, which was formerly known as the Oak Ridge Gaseous Diffusion Plant and often referred to as the former K-25 site.

“Due to the heavy contamination and state of the 1940s facility, K-27 was one of the environmental management’s highest cleanup priorities,” the DOE Office of Environmental Management, or EM, said in a May 31 newsletter. “The progress taking down the facility moves EM closer to fulfilling its Vision 2016—the removal of all five gaseous diffusion buildings from the site by year’s end. It is not only a significant goal for EM and Oak Ridge, but it will also mark the first time in the world that a uranium enrichment complex has been cleaned and removed.” [Read more…]

Demolition started Monday on K-27, the last of the big five uranium-enriching buildings at the former K-25 site, and officials expect the work to be complete by the end of the year.

The five buildings—K-25, K-27, K-29, K-31, and K-33—once used a process called gaseous diffusion to enrich uranium for atomic weapons and commercial nuclear power plants. Officials credit them for helping to win World War II and end the Cold War, and for playing significant roles in technological developments and the nuclear industry.

The K-25 site, which is now known as East Tennessee Technology Park or Heritage Center, was built during World War II as part of the Manhattan Project, a top-secret federal program to build the world’s first nuclear weapons. The site is now slowly being converted into a large industrial park.

“The majority of the property will be reused,” said Ken Rueter, president and project manager for UCOR, or URS |CH2M Oak Ridge LLC, the U.S. Department of Energy’s cleanup contractor in Oak Ridge. [Read more…]

Demolition work could start early this year on the K-27 Building, the last of five gaseous diffusion buildings at the former K-25 site, now known as East Tennessee Technology Park or Heritage Center. The giant buildings were once used to enrich uranium for nuclear weapons and nuclear power plants, starting during World War II and continuing through the Cold War.

Deactivation work continues at the K-27 Building, preparing it for demolition. At the beginning of December, deactivation of the building was more than 96 percent complete. Workers continue to remove transite paneling on the building, but that job is 80 percent complete.

Sue Cange, manager of the U.S. Department of Energy’s Oak Ridge Office of Environmental Management, has previously said that demolition work could start on the building in early 2016 and be complete by the end of the year.

Demolition work on the former K-31 Building, the fourth of the five buildings to be demolished, was completed in June. [Read more…]

Demolition now complete on four of five gaseous diffusion buildings

Demolition of the large K-31 Building in west Oak Ridge means that 200 acres of flat land are now available for industrial development at East Tennessee Technology Park, officials said.

“It’s the largest parcel of land available at ETTP,” said Sue Cange, manager of the U.S. Department of Energy’s Oak Ridge Office of Environmental Management.

Infrastructure is already in place, including water, sewer, roads, and electricity, Cange said. Also, ETTP is close to Interstate 40, a short rail line, and possibly an airport. (There are plans to build an airport at the site, which is also known as Heritage Center.)

K-31 is the fourth of five gaseous diffusion buildings demolished at ETTP. The site, which has also been known as K-25 and Oak Ridge Gaseous Diffusion Plant, was built during the Manhattan Project in World War II as part of a top-secret federal program to build the world’s first atomic bombs. Officials say it helped to win the Cold War, enriching uranium for commercial nuclear power plants and nuclear weapons.

But operations ended in 1985, and the site was permanently shut down in 1987. DOE then began cleanup operations and—with the help of contractors, a nonprofit organization, and others–is converting it into a large private industrial park. [Read more…]

DOE, UCOR demolish last piece of K-25, once the world’s largest building

The last section of the former K-25 Building in west Oak Ridge was demolished on Thursday.

It was once the world’s largest building under one roof, built by the U.S. government in less than two years as part of a top-secret race to build the world’s first atomic bombs during World War II.

Officials say it also helped win the Cold War.

But five years after demolition started, the K-25 Building is gone. Officials, workers, and invited guests watched the last section of the giant building crash to the ground on Thursday.

The mile-long, U-shaped K-25 Building enriched uranium through a process called gaseous diffusion. It was the largest facility in the U.S. Department of Energy complex. Debris shipments are expected to be completed in the spring of 2014.

The $1.1 billion project is under budget and ahead of schedule. [Read more…]
