The final drums of old transuranic waste stored at Oak Ridge National Laboratory have been prepared for disposal.

The U.S. Department of Energy’s Oak Ridge Office of Environmental Management reported Tuesday that it had recently completed installing vents and sample ports in the final drums of the legacy transuranic waste stored at ORNL. The decade-long effort ensures that the drums do not contain any hazardous gases that could cause rapid combustion.

The ventilated unit where the drums were vented is closed and explosion-proof, DOE said. It is capable of withstanding a combustion event while keeping workers and ORNL, the nation’s largest multi-program national laboratory, safe, DOE said.

“Venting and sampling these drums is an essential part of the waste disposal process,” ORNL Portfolio Federal Project Director Bill McMillan said. “Now that we can ensure the safety of each drum, they are ready for transport to the Transuranic Waste Processing Center for processing and subsequent shipment to a permanent disposal facility away from Oak Ridge.” [Read more…]

For the first time in 30 years, spent nuclear fuel from the High Flux Isotope Reactor at Oak Ridge National Laboratory has been dissolved at the Savannah River Site in South Carolina.

The work is important because it is expected to allow the reactor, known as HFIR, to continue its mission, according to the U.S. Department of Energy Office of Environmental Management.

HFIR, which uses highly enriched uranium, is one of the world’s most powerful nuclear research reactor facilities. It’s the highest flux reactor-based source of neutrons for research in the United States. Flux refers to the rate of flow of fluids, particles, or energy. In HFIR’s case, the flux is measured in neutrons per square centimeter per second. HFIR is used for neutron scattering and isotope production, among other missions.

ORNL will reach its maximum capacity for storing HFIR fuel in fiscal year 2020, the DOE Office of Environmental Management, or EM, said in an “EM Update” electronic newsletter on Tuesday. [Read more…]

Oak Ridge is home to more higher-risk excess contaminated facilities than any other U.S. Department of Energy site in the nation, but recent demolition projects are helping change that. This month, the Oak Ridge Office of Environmental Management, or OREM, eliminated two buildings from the higher-risk list.

The projects were part of DOE’s Excess Contaminated Facilities Initiative, an effort to stabilize facilities, reduce risks, and in some cases accelerate demolition schedules. Oak Ridge is of particular interest since the site houses 297 “excess” facilities—facilities that are no longer operational or serving DOE’s missions. As of December 2016, Oak Ridge contained 60 of DOE’s inventory of 203 higher-risk excess facilities.

“These projects are highlighting EM’s value as crews are removing risks and clearing land for DOE’s important ongoing missions,” said OREM Federal Project Director Brian Henry. “Tearing down these high-risk facilities is a first step with many more planned in the years ahead.” [Read more…]

Note: This story was published in the November 21 edition of “EM Update” by the U.S. Department of Energy Office of Environmental Management. EM Update recently spoke with Jay Mullis, the new manager of the Oak Ridge Office of Environmental Management (OREM), about his vision and priorities for the EM program in Oak Ridge.

What are your main priorities going forward as the new manager of OREM?

Overall, I want to ensure our program maintains the momentum we’ve achieved during the past several years. First, it is important for us to continue pushing forward to complete cleanup at the East Tennessee Technology Park (ETTP, also known as the former K-25 site) by 2020. This will facilitate the transfer of the site back to the community so it can be transformed into a vibrant industrial park capable of generating jobs and economic growth for the region. It will also allow our program to shift its focus and resources toward cleanup at two important, active DOE sites: the Y-12 National Security Complex and Oak Ridge National Laboratory (ORNL). Before we finish our cleanup mission at ETTP, we must also fulfill our historic preservation commitments to preserve and celebrate the many achievements that occurred there during the Manhattan Project and Cold War. 

Secondly, it is very important that we begin laying the foundation for our next big challenges at Y-12 and ORNL. That began on November 20, when we broke ground on the new Mercury Treatment Facility at Y-12. This critical piece of infrastructure will provide an important control measure for mercury and opens the door for us to clean and remove mercury contaminated facilities and soils. Additionally, it is crucial to construct another onsite disposal facility that will provide the space necessary for the waste generated by completing cleanup at Y-12 and ORNL. 

Finally, we will continue our focus on eliminating Oak Ridge’s waste inventory. We are making progress packaging and disposing transuranic waste from ORNL with the Waste Isolation Pilot Plant again accepting shipments. We are working to eliminate the remaining portion of the uranium-233 inventory from ORNL to improve safety and significantly reduce security costs.

This story, which has been lightly edited here, was originally published in the EM Update on October 17 by the U.S. Department of Energy Office of Environmental Management.

Reindustrialization efforts at the East Tennessee Technology Park have brought new life to an old barge access area out of service for decades.

The U.S. Department of Energy’s Oak Ridge Office of Environmental Management is cleaning and converting the former uranium enrichment complex into a private sector industrial park, and companies are seeing significant signs of progress and potential.

In September, UniTech Services Group, a private business at ETTP, the former K-25 site, needed to transport large industrial equipment from Michigan and noted the site’s neglected barge area. The company worked with DOE and the Community Reuse Organization of East Tennessee to use this area, and successfully shipped the equipment to ETTP using the Mississippi, Ohio, and Tennessee navigable river systems.

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 Friday, July 28.

Workers began demolishing the Poplar Creek facilities this month, bringing Oak Ridge’s environmental management, or EM, program closer to completing major cleanup at the East Tennessee Technology Park by 2020.

“Demolishing the Poplar Creek facilities is significant for our program because it continues the visible transformation of ETTP’s skyline, and it removes the most contaminated facilities remaining at the site,” said Jay Mullis, acting manager of the U.S. Department of Energy’s Oak Ridge Office of Environmental Management, or OREM.

OREM has taken down more than 400 facilities at ETTP, including all five former uranium enrichment facilities. That’s about 10 million square feet of buildings that have been removed.

ETTP, also known as Heritage Center, is the former K-25 site in west Oak Ridge. The site was built to help enrich uranium for atomic bombs during the top-secret Manhattan Project in World War II, and it continued to operate through the Cold War, including to enrich uranium for nuclear power plants.

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…]

This story and photos were published in the May 17 edition of the EM Update newsletter by the U.S. Department of Energy Office of Environmental Management.

Oak Ridge’s environmental management, or EM, program and contractor URS | CH2M Oak Ridge have prevented more than 1,000 pounds of mercury from entering the environment at the Y-12 National Security Complex.

This work, part of the U.S. Department of Energy’s Excess Contaminated Facilities initiative, enables demolition and disposal of massive mercury-contaminated equipment to begin this month.

Workers are inspecting and cleaning the pipes and column exchange (COLEX) equipment on the west side of Alpha-4 at Y-12. They have tapped and drained approximately 2,100 feet of the 5,700 feet of piping so far, retrieving large amounts of mercury, and more is expected as work continues. EM will address and remove the remaining portions on the facility’s east and south sides in the future.

“This project has proven to be a very successful investment for our program,” said Oak Ridge Office of EM Acting Manager Jay Mullis. “We set out to remove risks and enhance safety through the Excess Contaminated Facilities initiative, and our efforts at Alpha-4 will prevent thousands of pounds of mercury from leaking into the environment.” [Read more…]

Sue Cange, who was an Oak Ridge manager, has been named principal deputy assistant secretary of the U.S. Department of Energy Office of Environmental Management, or EM.

EM announced the appointment on Thursday.

Cange had been manager of the Oak Ridge Office of Environmental Management. Oak Ridge Today reported in early October that she was moving to Washington, D.C., to become interim principal deputy assistant secretary for the U.S. Department of Energy Office of Environmental Management. She was temporarily serving in the role formerly filled by Mark Whitney, who has taken a job in the private sector. Whitney is also a former manager of the Environmental Management program in Oak Ridge.

“Sue is a trusted and effective leader with a deep understanding of EM’s cleanup mission and passion for advancing our mission,” EM Assistant Secretary Monica Regalbuto said in a press release Thursday. “With a strong track record of leading organizations to complete cleanup work safely and efficiently, she will be integral to our progress.” [Read more…]
