Two federal agencies have agreed to build a K-25 Viewing Platform at the historic site in west Oak Ridge that was used to enrich uranium for nuclear weapons and nuclear power plants during World War II and the Cold War. The design is expected to be complete in March and the building completed by the end of 2023.

The construction agreement for the viewing building at the former K-25 site was signed by the U.S. Department of Energy’s Oak Ridge Office of Environmental Management and U.S. Army Corps of Engineers.

The viewing platform will give visitors a view of the large 44-acre footprint of the former K-25 Building. K-25, which was the world’s largest building, was erected during World War II as part of the Manhattan Project to help enrich uranium for the world’s first atomic bombs during World War II. The K-25 Building was demolished in 2013, and many other structures at the site have been removed as the federal government turns over property for private development.

The K-25 Building site itself is now part of the Manhattan Project National Historical Park. That project commemorates the workers, equipment, and processes used during the Manhattan Project in Oak Ridge, Tennessee; Hanford, Washington; and Los Alamos, New Mexico.

The K-25 Viewing Platform and associated exhibits are the final components of a multi-project agreement that the Oak Ridge Office of Environmental Management signed in 2012, clearing the way for demolition of the North Tower of the mile-long, U-shaped K-25 Building. The projects commemorate the history of the K-25 site, which has also been known as the Oak Ridge Gaseous Diffusion Plant.

The executive order issued by President Joe Biden in September requires federal employees to be fully vaccinated by November 22, the U.S. Department of Energy said. DOE said 84 percent of the department’s federal workforce was, at the time, fully vaccinated.

To comply with the November 22 deadline, DOE’s employees must complete their vaccinations by November 8. This would apply to the first Johnson & Johnson shot, a one-shot vaccine, or the second Moderna or Pfizer-BioNTech shots, both two-shot vaccines. People aren’t considered fully vaccinated until two weeks after the final dose of a vaccine.

The U.S. Department of Energy notified its staff of the vaccine requirement on Tuesday last week.

“Protecting your health and safety is our top priority,” DOE told its staff. “To help ensure this, President Biden issued an executive order requiring all federal employees to be fully vaccinated by November 22, 2021. This applies to all federal employees regardless of remote, telework, or onsite reporting status, except in limited circumstances in which an employee may be exempt due to a legally required accommodation.”

Five contracts worth up to $24.9 million total have been awarded to small businesses to help support the cleanup of federal sites in Oak Ridge.

The awardees include one company based in Oak Ridge and two based in Knoxville.

The awards were announced last week by the U.S. Department of Energy’s Oak Ridge Office of Environmental Management as part of its Characterization, Deactivation/Demolition, and Remediation Services contract.

The Oak Ridge Office of Environmental Management, or OREM, said it will use the awards to advance cleanup progress across the Oak Ridge Reservation by issuing task orders to conduct characterization, demolish lower hazard buildings, dispose waste, and provide technical support.

The U.S. Department of Energy is considering whether to lease space to store elemental mercury from sites across the country.

The facility could store about 1,200 metric tons (1,300 tons) of elemental mercury. The waste has been generated at sites in the United States, mostly at gold mining operations, according to the DOE Office of Environmental Management.

The mercury that could be stored at the leased facility is separate from the 1,200 metric tons of mercury stored at the Y-12 National Security Complex in Oak Ridge. The Y-12 mercury, about 2.6 million pounds stored in seamless steel flasks, was acquired for lithium-6 isotope separation operations for thermonuclear weapons.

The partial shutdown of the federal government is not affecting the U.S. Department of Energy’s cleanup program in Oak Ridge, a spokesperson said Friday.

The U.S. Environmental Protection Agency provides federal oversight of the work, and EPA is one of the federal departments and agencies affected by the partial government shutdown.

But on Friday, Ben Williams, spokesperson for the DOE Oak Ridge Office of Environmental Management, said the shutdown is not affecting the office’s cleanup work at this time. [Read more…]

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.

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…]

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, 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…]
