Sue Cange will be moving at least temporarily to Washington, D.C., to become interim principal deputy assistant secretary for the U.S. Department of Energy Office of Environmental Management. She will be temporarily serving in the role formerly filled by Mark Whitney, who has taken a job in the private sector.

Whitney is a former manager of the Environmental Management program in Oak Ridge. He has been appointed chief operating officer of AECOM’s nuclear and environment strategic business unit. He worked for DOE for 11 years and served in both the Environmental Management office and the National Nuclear Security Administration, AECOM said in a press release.

Cange is expected to move in the next few weeks, sometime in October, said Ben Williams, DOE spokesperson for the Oak Ridge Office of Environmental Management. [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…]

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

K-27 Demolition

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…]

Demolition starts on last of big five uranium-enriching buildings at K-25

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 could start this year on K-27, last of five gaseous diffusion buildings

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…]

The U.S. Department of Energy has awarded a $2.1 million fixed-price contract to a small business based in Michigan, CTI and Associates, to perform asset recovery and demolition work at the old electrical switchyard at East Tennessee Technology Park.

The scope of the work includes removal and recycling of electrical equipment. The switchyard is adjacent to the K-27 Building in west Oak Ridge.

Copper, aluminum, and steel from the yard can be recovered for recycling. CTI has engaged an Alabama subcontractor, TCI, that specializes in electrical recycling. [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…]

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.
