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.

Workers are making significant progress removing asbestos and other hazardous waste from the Biology Complex at the Y-12 National Security Complex in a deactivation project that’s more than 60 percent complete, the U.S. Department of Energy said this week.

The work prepares the Biology Complex for demolition, possibly next year. The Biology Complex was originally built to recover uranium from process streams. It was later used for DOE’s research on the genetic effects of radiation from the late 1940s. When they operated, the facilities once had more people with doctorates than anywhere in the world, according to DOE.

Asbestos abatement teams from UCOR are working inside the six-story 9207 Facility and the three-story 9210 Facility. The first building is 256,600 square feet, and the second is 64,700 square feet.

“This project paves the way for EM (Environmental Management) to begin demolishing remaining buildings that comprise the Biology Complex next year,” the U.S. Department of Energy Office of Environmental Management said in an “EM Update” newsletter on Tuesday.

The largest and most visible buildings remaining at the East Tennessee Technology Park are being removed.

Demolition is under way on the Centrifuge Complex, according to the “EM Update” newsletter published last week by the U.S. Department of Energy Office of Environmental Management.

The demolition work is part of the project to finish cleanup at ETTP, the former K-25 site in west Oak Ridge, by the end of 2020. One of the three main sites in Oak Ridge, K-25 was built as part of the Manhattan Project, the top-secret federal program to build atomic weapons during World War II. The site continued to enrich uranium for nuclear weapons and commercial nuclear power plants through the Cold War. Its operations ended in the mid-1980s, and the site is now being converted into a private industrial park.

The Centrifuge Complex has more than 235,000 square feet, and sections of it reach heights of 180 feet. It was built in stages to develop and test centrifuge uranium enrichment technology, the “EM Update” said. The last of these facilities ceased operation in the mid-1980s.

The U.S. Department of Energy said its Office of Environmental Management and its contractors know the importance of training to ensure safety.

Recently, that training helped save a life in an unlikely place, DOE said in a story published Tuesday.

While eating lunch at a local restaurant, Eric Glenn, a radiological control technician at Isotek, noticed a man choking on his sandwich.

“I just heard a man coughing and he did the choking sign, so I ran over and gave him the Heimlich maneuver six or seven times,” Glenn said.

Work began in June to build the Mercury Treatment Facility at the Y-12 National Security Complex.

The Mercury Treatment Facility will allow the U.S. Department of Energy to clean up and demolish several large Y-12 buildings that used mercury to separate lithium for nuclear weapons during the Cold War in the 1950s and 1960s. The facility is expected to help reduce the amount of mercury in East Fork Poplar Creek, which flows through Oak Ridge.

DOE announced in December that it had awarded a $91 million contract to build the Mercury Treatment Facility. The contract, which could be in place for up to four years, was awarded to APTIM-North Wind Construction JV LLC.

A groundbreaking was held at the site in November 2017, and site preparations were completed by December 2018.

Federal site cleanup workers reported in August that they had begun removing contaminated sludge and debris from tanks, sumps, and valve boxes at Oak Ridge National Laboratory’s liquid and gaseous waste operations using a powerful, new trailer-mounted vacuum.

The equipment has already enhanced safety and operational efficiency, according to the U.S. Department of Energy Office of Environmental Management.

“Without the vacuum, personnel would be required to fully dress in personal protective equipment and remove the sludge and debris with shovels and buckets,” DOE said. “In addition to being closer to contaminated materials in confined spaces, workers would face an increased chance of slips and falls while climbing in and out of slippery areas in the protective suits.”

Using the vacuum technology has eliminated the risk of heat stress for employees, who would otherwise perform manual labor in protective suits during the hot Tennessee summer, DOE said. [Read more…]

One of the most contaminated buildings left at the East Tennessee Technology Park, the former K-25 site, has been demolished, federal officials said.

Demolition crews began tearing down Building K-633, which was once used to evaluate uranium enrichment equipment, in May and completed the project in June, according to the U.S. Department of Energy Office of Environmental Management.

The work was done by the Oak Ridge environmental management, or EM, program and its cleanup contractor URS|CH2M Oak Ridge, or UCOR.

“This project eliminates one of the most contaminated remaining buildings at the East Tennessee Technology Park,” DOE said.

Building K-633—the K-633 Test Loop Facility—is the fourth building Oak Ridge’s EM program has removed from ETTP’s Poplar Creek area since last year, DOE said. [Read more…]

Note: This is an edited version of a story that was first published by the U.S. Department of Energy Office of Environmental Management in an EM Update on Tuesday, Oct. 24.

Workers recently passed the halfway mark removing asbestos from a former research reactor at Oak Ridge National Laboratory as part of an effort to remove risks and prepare excess facilities in Oak Ridge for eventual demolition.

The asbestos abatement could continue until early 2018 inside Building 7500, also known as the Homogenous Reactor Experiment facility at ORNL, according to the U.S. Department of Energy’s Oak Ridge Office of Environmental Management. Crews are pulling out ceiling and floor tile, pipe and vessel insulation, and wall board.

The project further reduces risks after OREM and cleanup contractor URS | CH2M Oak Ridge, or UCOR, cleared all combustible materials and deactivated the heat detection system inside the building earlier this year.

Deactivating the system eliminated the need for personnel to enter the building for periodic inspections, and it allowed for removal of all hazardous energy sources as required before asbestos abatement. [Read more…]

This story was updated at 5 p.m. Aug. 30.

They haven’t agreed on a final budget number, but the Trump administration and the U.S. House and Senate have proposed spending between about $33 million and $52 million in the next fiscal year to continue disposing of uranium-233 waste materials that are stored at Oak Ridge National Laboratory in a building that is the oldest continuously operating nuclear facility in the U.S. Department of Energy complex.

The uranium-233, or U-233, waste is now stored in secure vaults in Building 3019, which was built in the 1940s at ORNL. Removing the waste could allow ORNL to relax its overall security posture, which will reduce costs, eliminate nuclear safety issues, and make the campus more conducive to collaborative science, according to a U.S. Senate Appropriations Committee report published in July.

Some of the waste is from a 1960s research and development test in New York, and it is being shipped to the Nevada National Security Site, a former nuclear weapons proving ground about 65 miles northwest of Las Vegas. In interviews this summer, DOE officials in Oak Ridge declined to discuss the amount of that waste that has been shipped to Nevada or to say how long the shipments might continue. But they are making progress, said Jay Mullis, acting manager of DOE’s Oak Ridge Office of Environmental Management.

Once all of those materials are shipped, the remaining U-233 at ORNL will be treated in “hot cell” facilities across the street from Building 3019, at Building 2026. The DOE’s Oak Ridge Office of Environmental Management owns both buildings.

Mullis said there is other U-233 waste stored in Building 3019, including from glovebox research at ORNL, from reactor plates, and from conglomerate materials. [Read more…]

The federal cleanup contractor in Oak Ridge was among 11 international winners of the Environmental Health and Safety Innovation Awards.

URS | CH2M Oak Ridge LLC, or UCOR, is the cleanup contractor for the U.S. Department of Energy’s Oak Ridge Office of Environmental Management.

UCOR was the public sector category winner, DOE said in a story published by the Office of Environmental Management on June 28. The award highlights the company’s use of sensors, drones, information technology, wearables, and occupational health and safety software in cleanup projects at the East Tennessee Technology Park, Y-12 National Security Complex, and Oak Ridge National Laboratory.

“They’ve done a tremendous job fostering a culture where employees are encouraged to approach and perform sensitive and complex projects in new and creative ways,” said Jay Mullis, OREM acting manager. “Our mission is reaping the benefits as we continue making progress while helping keep the workforce safe.” [Read more…]

Note: This story was updated at 12 p.m.

Sue Cange, former head of the federal government’s cleanup program in Oak Ridge, has been appointed as a visiting scholar at Vanderbilt University in Nashville, a spokesperson said Wednesday.

It’s a two-year appointment as a visiting scholar in civil and environmental engineering that started July 5, Vanderbilt University spokesperson Jim Patterson said. Cange has bachelor’s and master’s degrees in environmental engineering from Vanderbilt University.

Cange remains a paid U.S. Department of Energy employee, Patterson said. At Vanderbilt, she will help to establish a nuclear environmental engineering curriculum and internship program.

Cange is a former manager of the Oak Ridge Office of Environmental Management. She had most recently worked at U.S. Department of Energy headquarters in Washington, D.C. In December, she was named principal deputy assistant secretary of the U.S. Department of Energy Office of Environmental Management, or EM. She had previously been interim principal deputy assistant secretary, temporarily serving in the role formerly filled by Mark Whitney, who took a job in the private sector. Whitney is also a former manager of the Environmental Management program in Oak Ridge.

In January, Cange became acting assistant secretary for environmental management, the Exchange Monitor reported. She replaced Monica Regalbuto on a temporary basis, at about the time that President Donald Trump was inaugurated. Regalbuto was the Obama administration’s final appointee to the position that oversees DOE’s $6-billion-a-year legacy nuclear cleanup program.

But last week, the U.S. Department of Energy announced that James M. Owendoff had been promoted to principal deputy assistant secretary of the Office of Environmental Management, or EM, replacing Cange. Owendoff had served as a senior adviser to the assistant EM secretary since January 2010, DOE said. [Read more…]
