The U.S. Department of Energy estimates it could cost at least $7.2 billion to convert and dispose of tens of thousands of cylinders of depleted uranium hexafluoride, a dangerous, corrosive waste byproduct of the uranium enrichment process. Some of the waste came from the former K-25 site in Oak Ridge and is now stored in Ohio, but a portion of the converted depleted uranium could eventually be returned to Oak Ridge for use in nuclear weapons.

Some of the waste came from the former K-25 site in Oak Ridge and is now stored in Ohio, but a portion of the converted depleted uranium could eventually be returned to Oak Ridge for use in nuclear weapons.

DOE’s Office of Environmental Management has had about 67,000 cylinders of the depleted uranium hexafluoride (DUF6) stored at two conversion facilities in Paducah, Kentucky, and Portsmouth, Ohio. The facilities convert the DUF6 into two primary products, depleted uranium oxide (a more stable chemical form) and hydrofluoric acid, according to a report by the U.S. Government Accountability Office.

The UCOR contract to clean up federal sites in Oak Ridge has been extended one year to July 31, 2021, and the consideration of a new cleanup contract won’t be considered until November 2020 at the earliest.

The UCOR contract could be extended one additional year, to July 31, 2022, using two six-month options, depending upon contractor performance and progress.

Before the extension, UCOR’s contract had been scheduled to expire July 31, 2020.

UCOR works on cleanup projects for the U.S. Department of Energy at the East Tennessee Technology Park, Oak Ridge National Laboratory, and Y-12 National Security Complex. The work includes the demolition of old, contaminated buildings that are no longer used. The cleanup work is called environmental management, or EM.

Cleanup crews started a $4.7 million project this month to reduce maintenance and operations costs at the Molten Salt Reactor Experiment, which was shut down 50 years ago at Oak Ridge National Laboratory.

The project is expected to save nearly $25 million in costs, the U.S. Department of Energy Office of Environmental Management said in an “EM Update” published Tuesday.

The cost-reduction project will relocate employees stationed at the decades-old facility. Personnel currently housed in the building will move to other site locations to help with other projects, the “EM Update” said.

The project is expected to enhance the facility’s electrical distribution, sump pump, fire suppression, and monitoring systems.

“Although it was shut down 50 years ago, certain systems within the reactor building have continued to operate to keep the facility safe and stable until it can be demolished,” said the “EM Update,” with the Oak Ridge story contributed by Mike Butler. [Read more…]

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…]

Anne Marie White was sworn in on Thursday in Washington, D.C., as assistant secretary for environmental management at the U.S. Department of Energy.

Environmental management, or EM, is DOE’s cleanup program, and it’s one of the major federal programs in Oak Ridge.

As assistant secretary, White will provide leadership to continue the safe cleanup of the environmental legacy brought about from five decades of nuclear weapons development and government-sponsored nuclear energy research, a press release said. She will work closely with communities that have partnered with DOE and its predecessor agencies for many decades, the press release said. [Read more…]

The federal spending bill approved last week includes $639 million for the federal government’s cleanup program in Oak Ridge, including what could be full funding for a top priority deactivation and demolition project at the Y-12 National Security Complex.

The $639 million for the current fiscal year is an increase of $141 million or more, compared to recent fiscal years, and it’s the most money appropriated in a while.

Besides Y-12, the fiscal year 2018 funding will be used for U.S. Department of Energy cleanup projects at East Tennessee Technology Park (the former K-25 site) and Oak Ridge National Laboratory.

“It’s very positive for us,” said Jay Mullis, manager of the DOE Oak Ridge Office of Environmental Management, or OREM. Mullis gave a brief update at a meeting of the Oak Ridge Reservation Communities Alliance on Monday.

In addition to $125 million to deactivate and demolish the Biology Complex at Y-12, the fiscal year 2018 spending bill includes $17.1 million in funding for the planned Mercury Treatment Facility at Y-12, about $200 million for continued cleanup work at ETTP, and a total of roughly $12 million for the Environmental Management Disposal Facility, or EMDF. That’s a proposed landfill that could be west of Y-12 and accept waste from future cleanup work at Y-12 and ORNL, possibly early in the 2020s. The project plan for EMDF is expected to be open to public comment later this summer. [Read more…]

Former director Alvin Weinberg once called it the greatest technical achievement at Oak Ridge National Laboratory. It was inspired by the campaign to build a nuclear-powered aircraft in the 1950s, and it was the first reactor to ever operate using uranium-233.

Now parts of the Molten Salt Reactor Experiment that are too radioactively “hot” for humans could be entombed in concrete.

For now, the idea is only under study, and there is no guarantee that any part of the Molten Salt Reactor Experiment, a nuclear historic landmark that has been dormant for decades, will be entombed.

But it’s one of the proposals being evaluated by the U.S. Department of Energy’s Oak Ridge Office of Environmental Management. The goal is to finish the evaluation by the end of the year.

Jay Mullis, manager of the Oak Ridge Office of Environmental Management, presented the proposal to the Oak Ridge City Council and Site Specific Advisory Board in two separate meetings earlier this month. The entombment proposal is one of five items being evaluated as part of a 45-day review started by DOE’s Environmental Management, or EM, program in June. [Read more…]

GAO: DOE has more than 80 percent of U.S. government’s environmental liabilities

Note: This story was last updated at 3:20 p.m. September 4.

The U.S. Department of Energy is responsible for more than 80 percent of the U.S. government’s estimated $450 billion in environmental liabilities, a federal agency said in a report published this year.

The agency, the U.S. Government Accountability Office, added the government’s environmental liabilities to a high-risk list of federal programs and operations in a report published in February.

Total environmental liabilities for the federal government are estimated at $447 billion. DOE is responsible for about $372 billion of them, or 83 percent, according to a fiscal year 2016 estimate, the GAO said.

Most of DOE’s environmental liability is related to nuclear waste cleanup, the GAO said. Fifty percent of it is at two cleanup sites: the Hanford Site in Washington state and the Savannah River Site in South Carolina.

The GAO—an independent, nonpartisan agency that works for Congress—said DOE’s total reported environmental liability has generally increased since 2000. It’s roughly doubled from a low of $176 billion in fiscal year 1997 to the higher estimate of $372 billion in fiscal year 2016.

“In the last six years alone, EM (environmental management) has spent $35 billion, primarily to treat and dispose of nuclear and hazardous waste and construct capital projects to treat the waste, while EM’s portion of the environmental liability has grown over this same time period by over $90 billion, from $163 billion to $257 billion,” the GAO said.

In the past few fiscal years, DOE environmental management has spent about $6 billion per year. The budget request submitted to Congress by President Donald Trump in May asked for $6.5 billion for the DOE Office of Environmental Management, the largest request in a decade.

Oak Ridge has a DOE environmental management program. It received more than $400 million in funding per fiscal year between 2013 and 2016. The Oak Ridge Office of Environmental Management has major cleanup projects at the East Tennessee Technology Park (the former K-25 site), Oak Ridge National Laboratory, and Y-12 National Security Complex. Cleanup work depends upon funding, but it could continue into the mid-2040s. Although they might be in various stages, projects that are under way now include finishing demolition work at ETTP by 2020, disposing of uranium-233 at ORNL, addressing high-risk excess facilities at ORNL and Y-12, building a Mercury Treatment Facility at Y-12, and shipping transuranic waste to the Waste Isolation Pilot Plant in New Mexico.

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.

If excess funding is available, the federal cleanup program in Oak Ridge has a top priority: the Biology Complex at the Y-12 National Security Complex.

The budget request submitted to Congress by President Donald Trump on Tuesday, May 23, included $225 million for high-risk excess contaminated facilities at Y-12 and Lawrence Livermore National Laboratory in California.

It’s not clear how much of that money might be used in Oak Ridge, if the president’s budget request were approved. Officials said the allocations would be determined by U.S. Department of Energy headquarters.

But the Oak Ridge cleanup program, known as environmental management, has taken steps to ensure that some projects here, such as the planned demolition of Y-12’s Biology Complex, are “in a good position” if money becomes available.

On Friday, Jay Mullis, acting manager for the DOE Oak Ridge Office of Environmental Management, or EM, said the Biology Complex would be a primary priority if Y-12 gets some portion of the $225 million proposed by the Trump administration.

“Provided there is excess funding, that would be the building we would go after,” the Oak Ridge EM program said. [Read more…]

House bill keeps DOE Office of Science spending flat, increases NNSA funding

A House bill approved Wednesday rejected the Trump administration’s proposed funding cut of about $900 million for the U.S. Department of Energy Office of Science.

Instead of cutting, the House Appropriations Committee bill would keep spending flat for the Office of Science, holding it at $5.39 billion in the next fiscal year, the same as in the current fiscal year.

That could be good news for DOE Office of Science laboratories and offices here, including Oak Ridge National Laboratory and the Office of Scientific and Technical Information, or OSTI.

Separately, the House bill recommends a funding increase for the National Nuclear Security Administration. That’s something that the Trump administration had also proposed. The NNSA is a semi-autonomous agency within DOE, and its activities include nuclear weapons work, nuclear nonproliferation efforts, and naval reactors. The Y-12 National Security Complex in Oak Ridge is an NNSA site.

“Issues of national and economic security are continually on the forefront of the minds of all Americans,” said U.S. Representative Chuck Fleischmann, a Republican whose district includes Oak Ridge. “Last week, the House Appropriations Committee, on which I serve, approved the Fiscal Year 2018 Energy and Water Appropriations Bill. I was proud to help direct additional funding towards the national security programs at Y-12.

“Additionally, funding levels included in this legislation will allow for cleanup of high risk excess facilities at Y-12. This is the first step in a long process, and I want to assure my constituents that I will continue fighting to ensure that Y-12, Oak Ridge National Laboratory, and environmental management activities get the funding needed to continue their critical missions.” [Read more…]
