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 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…]

Traffic on Highway 58 and Highway 95 could be affected for two weeks starting Thursday by large, slow-moving equipment removing parts from a former electrical switchyard at the East Tennessee Technology Park in west Oak Ridge.

The work is being done by the U.S. Department of Energy’s Oak Ridge Office of Environmental Management. It’s part of the ongoing cleanup work at ETTP, the former K-25 site.

Workers are removing, disposing, and recycling components from a former ETTP electrical switchyard, known as K-732 Switchyard.

“For the next two weeks, this project requires the use of a specialized trailer on public highways to transport three large condensers that each weighs approximately 110 tons,” a press release said. “Motorists transiting the area during this time should be alert for slow-moving vehicles and expect occasional delays.” [Read more…]

An environmental assessment has been completed for the transfer of 170 acres at Heritage Center for a general aviation airport in west Oak Ridge, and the assessment found no significant impact, officials said Tuesday.

The assessment was completed by the U.S. Department of Energy Oak Ridge Office of Environmental Management. The land would be transferred to the Metropolitan Knoxville Airport Authority.

In August, officials said conditions are subject to change, but plans then called for starting construction on the airport at the former K-25 site in 2018. An estimate at that time said the airport could cost between $30 million and $40 million.

The airport would have a 5,000-foot runway that would accommodate general aviation aircraft including corporate jets, private airplanes, and emergency medical services aircraft. A development plan shows the airport at the south side of Heritage Center along Oak Ridge Turnpike, or State Route 58. [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…]

A new virtual museum helps preserve the history of the former K-25 site, which was built in west Oak Ridge to enrich uranium for atomic bombs during World War II and once had the world’s largest building under one roof.

The K-25 Virtual Museum was launched in November by the U.S. Department of Energy Oak Ridge Office of Environmental Management (OREM) as part of a memorandum of agreement for the interpretation of the historic site now known as East Tennessee Technology Park, or ETTP.

The debut of the online museum coincided with the November 10 signing of an agreement between the Department of Energy and the Department of Interior establishing the Manhattan Project National Historical Park. The Manhattan Project was a top-secret federal effort to build the world’s first atomic weapons during World War II.

The K-25 Virtual Museum can be viewed at http://www.k-25virtualmuseum.org/.

Note: This story was updated at 4:36 p.m.

Conditions are subject to change, but current plans call for starting construction on a general aviation airport at Heritage Center, the former K-25 site, in 2018. The current estimate range says the airport could cost between $30 million and $40 million, officials said Wednesday.

Work on an airport master plan is just starting, and it could take 12 months to complete, said Bill Marrison, president of the Metropolitan Knoxville Airport Authority. He said that plan will provide more details on subjects like cost and schedule.

The Oak Ridge airport would the third for the MKAA, which would own the site. The other two are McGhee Tyson in Blount County and Downtown Island in Knoxville.

Marrison said the Oak Ridge airport would be a reliever airport and help relieve congestion at the other two airports. He said McGhee Tyson is at capacity and there is no hangar space available, and Downtown Island has 100 people on its waiting list. [Read more…]

About 170 acres of land at a federal site in west Oak Ridge could be transferred to a nonprofit organization for a new general aviation airport that would feature a 5,000-foot runway and accommodate airplanes and helicopters.

The airport would be built on the south side of Heritage Center, which is also known as East Tennessee Technology Park and the former K-25 site. The runway would be close to and run roughly parallel to Oak Ridge Turnpike/State Route 58.

A draft environmental assessment, or EA, has been prepared for the property transfer. It evaluates the potential impacts of transferring the ETTP land from the U.S. Department of Energy to the nonprofit Metropolitan Knoxville Airport Authority. DOE and MKAA representatives will be available to discuss the proposed action during a public information session from 5-6:30 p.m. Wednesday, August 19, at the DOE Information Center. The Information Center is on the west end of the building that houses the Office of Scientific and Technical Information in east Oak Ridge.

No formal presentation is planned, and the public may stop by at any time during the session. [Read more…]

The driver of this Chevrolet Cavalier was flown by a medical helicopter to a hospital after apparently crashing through a guardrail and into a rock embankment, right, below a DOE haul road on Highway 95 in west Oak Ridge on Wednesday afternoon.

A car driver was flown by medical helicopter to a hospital after crashing through a guardrail and into a rock embankment below a U.S. Department of Energy haul road that crosses over Highway 95 in west Oak Ridge on Wednesday afternoon.

The name and condition of the driver weren’t immediately available after the one-vehicle, one-person crash. The collision occurred in a curvy section of Highway 95 near the western entrance to the Y-12 National Security Complex on Bear Creek Road.

The haul road is used to move debris from the East Tennessee Technology Park, the former K-25 site, to the Environmental Management Waste Management Facility west of Y-12. [Read more…]
