Crews are expected to finish remediating soil, reversing or stopping environmental damage at the former K-25 site in west Oak Ridge this year, and federal cleanup managers are shifting their focus to groundwater. It’s the final phase of cleanup at the former uranium enrichment site.

Now also referred to as Heritage Center and East Tennessee Technology Park (ETTP), the K-25 site produced fuel for nuclear weapons and reactors starting in the top-secret Manhattan Project during World War II and continuing through the Cold War. The site has been shut down for almost four decades, and a massive cleanup project has been under way for many years.

The groundwater work can begin with the recent signing of two records of decision between the U.S. Department of Energy’s Oak Ridge Office of Environmental Management, U.S. Environmental Protection Agency, and Tennessee Department of Environment and Conservation. That’s according to “EM Update,” an electronic newsletter published by DOE’s Office of Environmental Management.

The U.S. Army Corps of Engineers has awarded Geiger Brothers a $9.9 million contract to build the K-25 Viewing Platform at the East Tennessee Technology Park in Oak Ridge. The Viewing Platform will help commemorate what was once the world’s largest building and part of the Manhattan Project, a top-secret federal program to build the world’s first atomic weapons during World War II. The site enriched uranium for nuclear weapons and nuclear power plants through the Cold War.

The K-25 Viewing Platform will be next to the K-25 History Center, which opened about three years ago. It will give visitors a complete view of the former building’s massive 44-acre footprint.

While the K-25 History Center focuses on the men and women who built and operated the Oak Ridge Diffusion Plant during the Manhattan Project and Cold War, this facility will help visitors understand the scope and magnitude of the former K-25 Building, a press release said.

The U-shaped K-25 Building was a mile long. It was demolished in 2013.

Construction on the Viewing Platform is scheduled to begin in May 2023, and it is expected to be complete in late 2024, the press release said.

A company that Microsoft co-founder Bill Gates helped launch in 2006 is working with a federal cleanup contractor in Oak Ridge to extract rare isotopes from nuclear materials for cancer treatment research.

The project will significantly increase the number of cancer treatment doses available each year, federal officials and company executives said Friday. It will help remove highly enriched fissile nuclear material from Oak Ridge National Laboratory and save taxpayers an estimated $90 million, the officials and executives said. And it will recycle an isotope that would otherwise be “irretrievably lost” as the nuclear material, uranium-233, is converted into a disposal-ready form.

The U.S. Department of Energy, Isotek Systems LLC, and TerraPower celebrated with an announcement of the project in Oak Ridge on Friday morning.

TerraPower, which is based in Bellevue, Washington, where Gates is chairman, is particularly interested in actinium-225. That isotope can be extracted from thorium-229. The thorium will be removed from the fissile material, the uranium-233 stored at ORNL, by the federal cleanup contractor, Isotek.

The unique agreement, a public-private partnership, is expected to allow TerraPower the ability to make 100 times more actinium-225-based cancer treatment doses per year than the 4,000 doses that are currently available worldwide. TerraPower could first offer actinium-225 in late 2020, company executives said.

The largest and most visible buildings remaining at the East Tennessee Technology Park are being removed.

Demolition is under way on the Centrifuge Complex, according to the “EM Update” newsletter published last week by the U.S. Department of Energy Office of Environmental Management.

The demolition work is part of the project to finish cleanup at ETTP, the former K-25 site in west Oak Ridge, by the end of 2020. One of the three main sites in Oak Ridge, K-25 was built as part of the Manhattan Project, the top-secret federal program to build atomic weapons during World War II. The site continued to enrich uranium for nuclear weapons and commercial nuclear power plants through the Cold War. Its operations ended in the mid-1980s, and the site is now being converted into a private industrial park.

The Centrifuge Complex has more than 235,000 square feet, and sections of it reach heights of 180 feet. It was built in stages to develop and test centrifuge uranium enrichment technology, the “EM Update” said. The last of these facilities ceased operation in the mid-1980s.

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…]

Tennessee officials have approved the demolition of two large buildings at the Biology Complex at the Y-12 National Security Complex.

The Biology Complex once housed more people with doctorates than anywhere in the world, according to the U.S. Department of Energy. DOE has said the men and women who worked there radically enhanced the world’s knowledge in biology, including the discovery of the Y chromosome.

Y-12 announced in December that the Tennessee Historical Commission had approved the demolition of the two buildings: Buildings 9207 and 9210. The buildings date back to the Manhattan Project, a top-secret federal program to build the world’s first atomic weapons during World War II. Oak Ridge was part of that project.

The demolition work at the Biology Complex is being overseen by the U.S. Department of Energy’s Oak Ridge Office of Environmental Management. [Read more…]

Federal officials have already approved the need for a new Lithium Production Facility at the Y-12 National Security Complex, and this month, they said it could be built on the east side of the 811-acre plant, possibly where the Biology Complex is now.

Current plans call for demolishing the Biology Complex. Officials had recently been saying that removing buildings from that complex would allow the area to be used for “modern national defense missions.” But it hadn’t been clear what those missions might be.

On May 12, Steven Wyatt, public affairs manager for the National Nuclear Security Administration Production Office, confirmed that the Lithium Production Facility could be built there. Y-12 is a NNSA site.

“We are in the early stages of planning for the Lithium Production Capability that is needed to replace the aging and obsolete 9204-2 building,” Wyatt said. “We are reviewing options for constructing a facility in the eastern portion of the Y-12 site, including the area of the Biology Complex.” [Read more…]
