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.

DOE asks for public comment about ETTP groundwater decision

Posted at
By Leave a Comment

The U.S. Department of Energy has asked for public comment about a proposed plan to reduce groundwater contamination in the main plant area of East Tennessee Technology Park, the former K-25 site in west Oak Ridge.

Comments are for an interim record of decision. There will be a public meeting Tuesday evening in Oak Ridge.

“The proposed plan identifies enhanced in situ bioremediation (EISB) as DOE’s preferred alternative to remediate six specific areas of groundwater in the main plant area of the East Tennessee Technology Park,” DOE said in a public notice distributed by the Tennessee Department of Environment and Conservation. “EISB is a method that involves using microorganisms to reduce contamination levels in these specific areas of groundwater. For these six areas, workers have excavated, or will excavate, the primary sources of contamination, as specified in the Record of Decision for Soil, Buried Waste, and Subsurface Structure Actions in Zone 2, East Tennessee Technology Park, Oak Ridge, Tennessee (DOE/OR/01-2161&D2).

The U.S. Army Corps of Engineers has awarded Geiger Brothers a $9.9 million contract to build the K-25 Viewing Platform at the East Tennessee Technology Park in Oak Ridge. The Viewing Platform will help commemorate what was once the world’s largest building and part of the Manhattan Project, a top-secret federal program to build the world’s first atomic weapons during World War II. The site enriched uranium for nuclear weapons and nuclear power plants through the Cold War.

The K-25 Viewing Platform will be next to the K-25 History Center, which opened about three years ago. It will give visitors a complete view of the former building’s massive 44-acre footprint.

While the K-25 History Center focuses on the men and women who built and operated the Oak Ridge Diffusion Plant during the Manhattan Project and Cold War, this facility will help visitors understand the scope and magnitude of the former K-25 Building, a press release said.

The U-shaped K-25 Building was a mile long. It was demolished in 2013.

Construction on the Viewing Platform is scheduled to begin in May 2023, and it is expected to be complete in late 2024, the press release said.

Much of the nation experienced an extreme cold snap over the recent holidays, and Tennessee was no exception with temperatures dipping to nearly zero degrees in Oak Ridge. Despite the bitter weather, preparations and recent upgrades helped prevent infrastructure failures during that time.

Many employees with EM cleanup contractor UCOR reported to work over the holidays to ensure issues were resolved at several essential facilities. (EM stands for environmental management.)

At the Environmental Management Waste Management Facility, advanced planning and preparation protected critical water management systems during the deep freeze over the nearly weeklong cold snap, including a 6.5-hour unplanned power outage.

The U.S. Department of Energy estimates it could cost at least $7.2 billion to convert and dispose of tens of thousands of cylinders of depleted uranium hexafluoride, a dangerous, corrosive waste byproduct of the uranium enrichment process. Some of the waste came from the former K-25 site in Oak Ridge and is now stored in Ohio, but a portion of the converted depleted uranium could eventually be returned to Oak Ridge for use in nuclear weapons.

Some of the waste came from the former K-25 site in Oak Ridge and is now stored in Ohio, but a portion of the converted depleted uranium could eventually be returned to Oak Ridge for use in nuclear weapons.

DOE’s Office of Environmental Management has had about 67,000 cylinders of the depleted uranium hexafluoride (DUF6) stored at two conversion facilities in Paducah, Kentucky, and Portsmouth, Ohio. The facilities convert the DUF6 into two primary products, depleted uranium oxide (a more stable chemical form) and hydrofluoric acid, according to a report by the U.S. Government Accountability Office.

Teresa Frady

Teresa Frady, president of the Community Reuse Organization of East Tennessee, is the Spotlight Interview guest on this week’s episode of the Gone Fission Nuclear Report podcast, which covers U.S. Department of Energy environmental management activities around the nation.

Hosted by Michael Butler, the episode is available on all podcast platforms and can be accessed at www.gonefissionpodcast.com, a press release said.

Frady shared with Butler’s listeners CROET’s mission to help DOE transition underused assets such as land, buildingsm and equipment to private sector companies at the East Tennessee Technology Park, also known as the Heritage Center. She recently replaced Lawrence Young, who had served as CROET’s president and chief executive officer since its founding in 1995.

“Our partnership with DOE in transferring federal land helps the region with creation of quality jobs but also adds the property to Roane County and City of Oak Ridge tax rolls,” she said in the press release. “This helps the communities and saves the federal government money since DOE no longer has to maintain those assets.”

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.”

Cleanup crews have started tearing down the largest remaining collection of buildings at the former K-25 site, which was built during World War II and enriched uranium for nuclear weapons and power plants through the Cold War.

The demolition work is occurring at the Centrifuge Complex at the K-25 site, now known as East Tennessee Technology Park or Heritage Center. The Centrifuge Complex is on the south side of ETTP. It includes the tall, white buildings visible from Highway 58.

Oak Ridge crews began demolishing the K-1200 section of the Centrifuge Complex in February. It’s the second of four sections.

Deactivation and demolition work in the first section of the complex was recently completed. That portion was a Manhattan Project facility built for research and development in 1944.
