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…]

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…]

About half of the uranium-233 waste stored in Building 3019 at Oak Ridge National Laboratory has been shipped to a disposal facility in Nevada.

The shipments were completed in August, said Jay Mullis, manager of the U.S. Department of Energy’s Oak Ridge Office of Environmental Management.

But federal officials were only recently able to announce the end of the shipments of the waste from the Consolidated Edison Uranium Solidification Program, or CEUSP. The waste contained radioisotopes of uranium from a 1960s research and development test of thorium and uranium reactor fuel at the Consolidated Edison Indian Point-1 reactor in New York. The test was sponsored by the Atomic Energy Commission, a predecessor to the U.S. Department of Energy.

The shipments were completed 10 months ahead of schedule, Mullis told the Oak Ridge Site Specific Advisory Board on Wednesday, November 8. The CEUSP waste had been treated and turned into a ceramic matrix. It was shipped from Building 3019 at ORNL, where it had been stored, to the Nevada National Security Site, a former nuclear weapons proving ground about 65 miles northwest of Las Vegas. DOE started shipping the waste materials to the Nevada National Security Site in May 2015. [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…]

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, 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.

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…]

DOE: Pavement collapse at ORNL a significant distance from U-233 storage area

A pavement collapse at Oak Ridge National Laboratory in early June was a significant distance from an area where uranium-233 is stored at Building 3019, the U.S. Department of Energy said Monday.

The collapse of about 36 square feet of pavement was near Building 3019B, which is an inactive facility, the DOE Oak Ridge Office of Environmental Management said.

The hot cells in the facility were not affected, and they do not contain radioactive material, DOE said.

“There were no immediate safety hazards to personnel, but as a precaution, the area was barricaded until crews made repairs,” DOE said.

Uranium-233, or U-233, is a fissionable material, and Building 3019 area is a secure and controlled area. The pavement collapse was reported by the Defense Nuclear Facilities Safety Board on June 19. [Read more…]

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.

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…]

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…]

Construction could start this year on the K-25 History Center at the East Tennessee Technology Park in west Oak Ridge, federal officials said. Plans also call for an Equipment Building and Viewing Tower at the site. Although the projects depend upon funding, the goal is to finish the work by 2019.

The K-25 site was one of three large sites built by the federal government in Oak Ridge during World War II to help make the world’s first atomic weapons as part of the top-secret Manhattan Project. The other two sites were X-10, which is now known as Oak Ridge National Laboratory, and Y-12, now the Y-12 National Security Complex.

At K-25, the three history-related facilities will have three missions. The History Center will tell the story of the workers. The Equipment Building will focus on the technology. And the Viewing Tower will show visitors the size of the site. All three facilities will be on the south side of the former mile-long, U-shaped K-25 Building.

K-25 used a process called gaseous diffusion to enrich uranium for atomic weapons and, later, for commercial nuclear power plants. Officials and contractors have said that K-25 helped win the Cold War. The site is now known as Heritage Center or East Tennessee Technology Park.

Preserving its history is part of a Memorandum of Agreement that was signed in August 2012 and allowed for the complete demolition of K-25, once the world’s largest building under one roof. The historic preservation work is expected to cost about $20 million total. [Read more…]
