SNS-Second-Target-Station
More than 200 scientists from around the world met from Oct. 27 to 29, 2015, at the U.S. Department of Energy’s Oak Ridge National Laboratory to provide input on the scientific instruments that would be installed at a proposed Second Target Station, or STS, pictured above at center right at the Spallation Neutron Source.

The next decision about the second target station at the Spallation Neutron Source could be made later this year or in the first quarter of next year, U.S. Energy Secretary Dan Brouillette told a House subcommittee on Thursday. The next decision would include an alternative selection and a cost range.

The $1.4 billion SNS is located on Chestnut Ridge at Oak Ridge National Laboratory. It provides neutrons for research.

The second target station has been part of SNS plans for many years. It’s one of two upgrades being pursued at SNS. The other is a proton power upgrade, which is expected to double the power of SNS’s proton beam from 1.4 megawatts to 2.8 megawatts.

The second target station has a current estimated cost range of $800 million to $1.5 billion. The U.S. Department of Energy said the second target was needed more than a decade ago, in January 2009. The second target station would use a narrow proton beam and a compact, rotating, water-cooled tungsten target. It is expected to fill gaps in materials research that require the combined use of intense, cold (longer wavelength) neutrons and instruments that can help analyze complex materials. It could have up to 22 experimental beamlines.

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 Mayor Pro Tem Rick Chinn and his brother Ryan are minority partners in the project to build apartments at the former American Museum of Science and Energy site.

Rick Chinn, a developer, said this month that the project will bring much-needed apartments to the city, allowing more people who work in Oak Ridge to live here. The apartments are being built as RealtyLink, a South Carolina developer, plans to build more new stores across South Tulane Avenue at Main Street Oak Ridge, the redevelopment of the former Oak Ridge Mall.

Now called Main Street Lofts, the apartment project has included an agreement to reduce property taxes and the transfer of what had been federal property from the U.S. Department of Energy to the city and then to a developer. It will include the demolition of the former AMSE building. It is expected to include seven three-story buildings with 226 apartment units on 10 acres.

Rick Chinn and his father, Richard Chinn, a member of the Oak Ridge Industrial Development Board, have been abstaining from votes related to the apartment project for at least a year.

They have not been required to explain their abstentions, but Oak Ridge Today has asked Rick and Richard Chinn why they have been abstaining.

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 Oak Ridge City Council is interested in a proposed test track and research facility or motorsports park at Horizon Center.

The seven City Council members unanimously expressed interest in the proposed project, which could cost more than $50 million and cover more than 300 acres, during a Monday night meeting. The proposal is still in the early conceptual stage, and Council doesn’t have a specific plan to consider or endorse yet.

There are significant questions about the unusual project, which would be in west Oak Ridge, a few miles northeast of the former K-25 site. They include the questions of whether some potential uses such as a hotel would be allowed by the deed restrictions at the site, whether motorsports would be allowed under the industrial zoning, and whether a recreational vehicle park and outdoor music would be appropriate there.

Oak Ridge City Council member Ellen Smith said there are legal constraints on the property. Certain kinds of uses are allowed, and some, such as homes and hotels, are not, Smith said. She said the U.S. Department of Energy was hoping to foster industrial development on the former federal property.

It’s not clear what position DOE might take on the proposed use, and it’s not clear whether the site would be a test track and research facility for non-spectators, a motorsports park for spectators, or a combination of the two.

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.

Federal officials have approved the need for a new Lithium Production Facility at the Y-12 National Security Complex, and in May 2018, they said it could be built on the east side of the 811-acre plant, possibly where the Biology Complex, the brick building at center, is now.

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.

A recent Roane State Community College graduate is researching climate change and the microorganisms that contribute to it.

Rachel Andrews, a Morgan County resident who graduated from the community college in May 2019, is an intern at Oak Ridge National Laboratory. She’s doing research with Christopher Schadt in the Biosciences Division at the lab.

They are investigating methane production in peat, which is formed by the partial decomposition of plants in wet, acidic conditions of bogs. Scientists say methane gas is one of the major contributors to a warming planet.

“We study the methanogens that live in peatland soil,” Andrews said in an emailed response to questions about her research. She said these microorganisms produce quite a bit of methane and carbon dioxide, also identified as a culprit in climate change.
