Crews are expected to finish remediating soil, reversing or stopping environmental damage at the former K-25 site in west Oak Ridge this year, and federal cleanup managers are shifting their focus to groundwater. It’s the final phase of cleanup at the former uranium enrichment site.

Now also referred to as Heritage Center and East Tennessee Technology Park (ETTP), the K-25 site produced fuel for nuclear weapons and reactors starting in the top-secret Manhattan Project during World War II and continuing through the Cold War. The site has been shut down for almost four decades, and a massive cleanup project has been under way for many years.

The groundwater work can begin with the recent signing of two records of decision between the U.S. Department of Energy’s Oak Ridge Office of Environmental Management, U.S. Environmental Protection Agency, and Tennessee Department of Environment and Conservation. That’s according to “EM Update,” an electronic newsletter published by DOE’s Office of Environmental Management.

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…]

He was a passionate advocate for preserving Oak Ridge’s history.

He was known for his bow ties and captivating storytelling. He once led the effort to save the former K-25 Building in west Oak Ridge, or at least part of it.

Now the legacy of Bill Wilcox will live on at the K-25 History Center.

Construction on the history center could start early next year on the second floor of Oak Ridge Fire Station Number Four. That fire station, previously transferred to the city, is on the south side of the former K-25 Building at East Tennessee Technology Park in west Oak Ridge.

Officials preparing for the construction of the history center gave tours of its future home at the fire station on Thursday. The tours followed a lunchtime celebration that featured tributes to Wilcox and included speeches and presentations by U.S. Department of Energy and Oak Ridge officials, and federal contractors and historic preservation advocates. Wilcox was hailed as the “father of K-25 historic preservation.”

“He would have been really proud,” said Ray Smith, Wilcox’s friend and Y-12 National Security Complex historian and city historian. “His legacy lives on.” [Read more…]

The last wall of the last of the big five buildings once used to enrich uranium at the former K-25 site will be demolished Tuesday.

Demolition on the last building, the K-27 Building, started in February.

The other four buildings—K-25, K-29, K-31, and K-33—were demolished between 2006 and 2015. All five of the huge buildings once used a process called gaseous diffusion to produce highly enriched uranium for atomic weapons and commercial nuclear power plants, starting during World War II and continuing through the Cold War. The largest was K-25, a mile-long U-shaped building.

When K-27 demolition is complete, it will be the first time that all of a site’s uranium-enriching gaseous diffusion buildings will have been cleaned up anywhere in the world, officials said.

“Demolition eliminates environmental hazards and prepares the land for productive reuse through deindustrialization,” a media advisory said. [Read more…]

Demolition work should be complete this month on K-27, the last of the big five buildings once used to enrich uranium for nuclear weapons and commercial nuclear power plants at the former K-25 site in west Oak Ridge, officials said last week.

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…]

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…]

K-31 Demolition: 200 acres now available for development at ETTP

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…]

URS Corporation has named new leaders at UCOR in Oak Ridge and SRR at the Savannah River Site in South Carolina.

Ken Rueter has been named president and project manager of UCOR, a partnership between URS and CH2M Oak Ridge LLC. The URS-led consortium is responsible for the cleanup of the U.S. Department of Energy’s East Tennessee Technology Park, the former K-25 site, in Oak Ridge.

Rueter will become president and project manager on Aug. 1. He will replace Leo Sain, who will lead the URS Decontamination and Decommissioning and Waste Management Strategic Business Group, which is based in Oak Ridge.

“Ken’s prior leadership in UCOR’s successful deactivation and decommissioning of the K-25 facility will be invaluable as we continue the D&D of the K-27 and K-31 gaseous diffusion facilities,” said Randall A. Wotring, president of federal services for URS. “I am confident he will build on the UCOR team’s recent accomplishments as well as his previous experiences at the East Tennessee Technology Park to ensure we continue to make safe progress for our DOE client.”

In a press release, URS said Rueter has 26 years of experience in the nuclear industry focusing on high-hazard nuclear operations, project management and integration, construction, and risk management. In his new assignment, he will be the senior executive for UCOR responsible for all deactivation and decommissioning (D&D) activities at the East Tennessee Technology Park. He was previously president and project manager of Savannah River Remediation LLC, or SRR, and prior to his role there, he was the chief operating officer for UCOR. [Read more…]

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.
