Cleanup crews have started tearing down the largest remaining collection of buildings at the former K-25 site, which was built during World War II and enriched uranium for nuclear weapons and power plants through the Cold War.

The demolition work is occurring at the Centrifuge Complex at the K-25 site, now known as East Tennessee Technology Park or Heritage Center. The Centrifuge Complex is on the south side of ETTP. It includes the tall, white buildings visible from Highway 58.

Oak Ridge crews began demolishing the K-1200 section of the Centrifuge Complex in February. It’s the second of four sections.

Deactivation and demolition work in the first section of the complex was recently completed. That portion was a Manhattan Project facility built for research and development in 1944.

Oak Ridge National Laboratory has been chosen as the site of an experimental facility to test materials that would withstand the harsh conditions of the plasmas created in fusion devices, which, researchers hope, could eventually provide carbon-free energy to people around the world.

The proposed facility, the Materials Plasma Exposure Experiment facility, or MPEX, has an estimated cost range between $87 million and $175 million. It would be in an existing facility in an area at ORNL known as the Energy Systems Test Complex.

Fusion devices would use the same reactions that power the sun. Temperatures inside a fusion reactor could reach millions of degrees.

Scientists are studying materials that could withstand the conditions inside fusion reactors by exposing them to prototypical plasma conditions. Plasma, the heated matter created in a fusion device, has high-energy neutrons, electrons, and ions. MPEX would study materials that face the plasma. Finding materials capable of withstanding the harsh environment remains a major hurdle to using fusion to produce energy.

A critical decision for the MPEX facility was completed in early February by the U.S. Department of Energy. ORNL is a DOE Office of Science lab. The critical decision, CD-1, is the second step in the five-step process that DOE uses to manage projects. The CD-1 decision included an alternative selection and a cost range.

Oak Ridge National Laboratory is involved in early research and using the Summit supercomputer to better understand components of the new coronavirus, which was first reported in China but is now being reported in a growing number of countries across the world, including the United States.

The early research at ORNL uses computational modeling and data analysis techniques on Summit, the world’s most powerful supercomputer. Results are not published yet, ORNL said Friday afternoon.

Oak Ridge Today has requested more information about the lab’s research, including who the work is for and what parts of the virus are being researched, but that information wasn’t immediately available.

The Centers for Disease Control and Prevention said it is closely monitoring the outbreak of respiratory illnesses caused by the new coronavirus, and there are ongoing investigations to learn more.

The new K-25 History Center will be hosting “Mud, a Photographic Exhibition of Life in the Secret City.” The exhibit will open on Thursday, February 27, and it will be available for viewing through the month of March.

There will be a grand opening and ribbon-cutting ceremony for the K-25 History Center at 10:30 a.m. Thursday, February 27.

During World War II, Oak Ridge was a quickly built as a secret government town of 70,000 workers who lived in a camp-like environment of barbed wire, security checkpoints, and code words, a press release said. Workers were fingerprinted, interviewed, assigned a job, and given a clearance badge. Housing was limited and cramped and often unheated.

Oak Ridgers who ventured into Knoxville were easy to spot. The quickly constructed secret city was blanketed in a thick layer of mud. As a result, its residents’ muddy shoes were a dead giveaway as to their origin. “The muddy conditions of Oak Ridge during the war was a commonality that all residents, regardless of occupation, had to contend with,” the press release said.

The K-25 History Center in west Oak Ridge will feature exhibits with more than 250 original artifacts and interactive galleries developed with help from almost 1,000 oral histories.

There will be a grand opening and ribbon-cutting ceremony for the K-25 History Center at 10:30 a.m. Thursday, February 27.

“The K-25 History Center was created to honor the amazing stories of the men and women who helped construct and operate the uranium enrichment complex that altered the global landscape during the Manhattan Project and Cold War,” the U.S. Department of Energy said.

The History Center is housed in 7,500 square feet of space on the second floor of the city-owned fire station at the former K-25 site, now known as Heritage Center. It was developed as part of a 2012 agreement that allowed DOE to demolish the North Tower of the former mile-long, U-shaped K-25 Building.

The K-25 History Center will have a grand opening ceremony on Thursday, February 27.

The ceremony, which will include a ribbon-cutting, is scheduled for 10:30 a.m. Thursday, February 27, at 652 Enrichment Street in west Oak Ridge.

The K-25 site, now known as Heritage Center, was built during World War II to help enrich uranium for the top-secret Manhattan Project, a federal program to build the world’s first atomic bombs. K-25 helped enrich uranium for “Little Boy,” a nuclear weapon dropped over Hiroshima, Japan, on August 6, 1945, shortly before the end of World War II.

After the war, K-25 enriched uranium for nuclear weapons and commercial nuclear power plants through the Cold War. The site was shut down in the mid-1980s, and it is being cleaned up and converted into a private industrial park. The site’s large uranium enrichment buildings have been demolished and so have many of the support buildings. Most of the cleanup is expected to be completed this year.

The proposed Lithium Processing Facility at the Y-12 National Security Complex could cost between $955 million and $1.65 billion, and it could be completed in 2031, the National Nuclear Security Administration said Thursday.

The Lithium Processing Facility could be built where the former Biology Complex is located on the east side of Y-12. That’s the NNSA’s preferred site. The Biology Complex is being prepared for demolition by the U.S. Department of Energy’s Office of Environmental Management.

On Thursday, the NNSA, which is part of the U.S. Department of Energy, said it had approved the conceptual design and cost range for the proposed 134,000-square-foot Lithium Processing Facility.

The facility will replace Y-12’s current lithium processing operations, which are located in a World War II-era building. That building, Building 9204-2, or Beta 2, has had materials fall from the ceiling, including chunks of concrete that reportedly weighed up to 200 pounds. The falling materials and concerns about worker safety have been cited by federal officials during congressional hearings in Washington, D.C.

The Roane State Foundation has won a $6,000 grant from the CNS Y-12 Community Investment Fund to help adult students in the community college’s programs in computer science, cybersecurity, and mechatronics, a press release said.

CNS operates the Y-12 National Security Complex in Oak Ridge, and the contractor established the fund through the East Tennessee Foundation in 2014 as part of its commitment to Oak Ridge and the surrounding communities.

Officials said the grant will fund scholarships to help students pay for industry-recognized certifications. Those certifications are important tools for graduates to pair with their college degree to demonstrate to employers they have the skills and documentations that often allow graduates to earn higher wages when going to work, the press release said.
