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…]

The Oak Ridge environmental management program and a small business specializing in environmental consulting, remediation, and deactivation and decommissioning are scheduled to complete field work and cleanup at the East Tennessee Technology Park’s K-732 Switchyard this month.

Workers removed extensive electrical infrastructure and equipment, transported three massive 110-ton condensers, and characterized, excavated, and backfilled three condenser basements and 20 underground vaults. They also remediated the soil and removed and transported nearly 56,000 gallons of oil. A condenser adjusts conditions and voltage on the electric power transmission grid. [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…]

Cleanup funding could be up for the U.S. Department of Energy under the budget request from the Trump administration for fiscal year 2018, and there could be benefits for Oak Ridge, according to budget documents.

President Donald Trump submitted his budget request to Congress on Tuesday, May 23. In that request, the DOE Office of Environmental Management, or EM, asked for $6.5 billion, the largest request in a decade. That would be $290 million above fiscal year 2016.

The funding request for Oak Ridge includes $390 million, or $78 million below fiscal year 2016, to continue deactivation and demolition of remaining facilities at East Tennessee Technology Park, continue preparing Building 2026 to support the processing of the remaining U-233 material at Oak Ridge National Laboratory, and to support activities for the Mercury Treatment Facility at Y-12 National Security Complex.

It’s not clear whether that $390 million in the funding request includes part of the $225 million in funding requested for high-risk excess contaminated facilities at Y-12 and Lawrence Livermore National Laboratory in California. It’s also not clear whether the total funding for Oak Ridge cleanup programs would be up or down, compared to previous years. The DOE public affairs office in Washington, D.C., has not responded to about a dozen budget-related inquiries from Oak Ridge Today since May 23.

Among the highlights of the EM request for Oak Ridge, according to budget documents posted online by DOE and an EM press release: [Read more…]

Funding for the Y-12 National Security Complex in Oak Ridge would be up about 25 percent under the budget request submitted to Congress in May, according to the National Nuclear Security Administration.

The total funding for Y-12 would be $1.64 billion, the NNSA said. That’s an increase of 25.4 percent over fiscal year 2016.

The budget request for fiscal year 2018, which starts October 1, was submitted by President Donald Trump to Congress on Tuesday, May 23. The NNSA request of $13.9 billion would increase funding by 7.8 percent compared to fiscal year 2017, Administrator Frank G. Klotz said during a teleconference with reporters on May 23.

Trump’s budget request has not yet been approved by Congress, where there has been bipartisan opposition, particularly to the proposed cuts. In Oak Ridge, sites and programs that could be cut include Oak Ridge National Laboratory, which would have a funding reduction of $206 million over two years, and the U.S. Department of Energy’s Energy Efficiency and Renewable Energy, or EERE.

But Y-12, a National Nuclear Security Administration site, could benefit if the president’s budget request were approved by Congress. A House spending bill introduced last week for federal energy and water departments appears to include proposed spending levels for the NNSA, a semi-autonomous agency within DOE, that are similar to what the Trump administration has proposed.

The U.S. Department of Energy and its cleanup contractor finished characterizing the Biology Complex at the Y-12 National Security Complex this month, identifying contaminants before demolishing and disposing of the buildings.

The characterization work was done by DOE’s Oak Ridge Office of Environmental Management and its contractor, URS | CH2M, or UCOR.

DOE said it was crucial to get crews into the complex before the working environment became too hazardous.

“Already, team members could not enter a building due to a failed roof,” the Department of Energy said in a story published online on Thursday. “Elsewhere, exterior tiles have fallen from the façade, and asbestos and other material present risks to workers due to roof leaks.”

Jay Mullis, acting manager for the Oak Ridge Office of Environmental Management, said the completion of the characterization work sets up the cleanup program to demolish Y-12’s Biology Complex when funds become available. [Read more…]

A new initiative by the Oak Ridge Office of Environmental Management is improving safety and preparing two of the federal sites—Oak Ridge National Laboratory and Y-12 National Security Complex—for cleanup and modernization, officials said. The initiative is an excess contaminated facilities initiative.

The congressionally funded cleanup initiative was stimulated by a report to Congress by the Governmental Accountability Office. The report noted that the U.S. Department of Energy designated more than 2,300 of its facilities as “excess,” meaning they’re not operating and no longer serve the department’s missions.

“Many of these facilities pose high risk from contamination and deteriorating structural integrities due to their age and the limited resources to maintain them,” the U.S. Department of Energy Office of Environmental Management, or EM, said in a story published January 31.

The Office of Environmental Management said more than a quarter of all DOE’s high-risk excess facilities are in Oak Ridge at either ORNL or Y-12. Y-12 has 90 excess facilities to address while ORNL has more than 200, DOE EM reported. [Read more…]
