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.

Nuclear materials and operations have been removed from an old building at the Y-12 National Security Complex, and that improves safety and reduces the risk to workers and the public, a federal safety board said.

The building, 9204-2, or Beta 2, is on the west side of Y-12. It’s one of nine buildings at the 811-acre site that once used machines known as calutrons to enrich uranium for atomic bombs as part of the top-secret Manhattan Project during World War II. It’s now used to produce lithium for nuclear weapons.

In an early September report, the Defense Nuclear Facilities Safety Board said Consolidated Nuclear Security and the National Nuclear Security Administration Production Office had officially downgraded Building 9204-2. It had been a category two hazard, but it is now less than category three. It’s considered non-nuclear.

Centrus Energy Corporation has a $15 million project to prepare K-1600, a building in the middle of the historic K-25 “footprint,” for demolition.

On Tuesday, Centrus announced that it had received a work authorization from the U.S. Department of Energy for decontamination and decommissioning (D&D) work at the building. The work will include removing and disposing of equipment and materials to make K-1600 non-radiologically contaminated and non-possessing (i.e. unclassified), a press release said. The work will occur between October 1, 2018, and September 30, 2019.

After the work is completed, DOE will be able to turn over K-1600 to a contractor to demolish it, the press release said. It’s one of the last remaining “legacy structures” on the 2,200-acre site of the World War II-era K-25 uranium enrichment plant, now known as the East Tennessee Technology Park, the press release said.

Many other buildings have been demolished there, including the five large gaseous diffusion buildings once used to enrich uranium for atomic weapons and commercial nuclear power plants. ETTP is now being converted into a large industrial park in west Oak Ridge. [Read more…]

Twenty tons of uranium could be used to produce tritium for nuclear weapons

About 20 metric tons of highly enriched uranium could be “down-blended” to low-enriched uranium and transferred to the Tennessee Valley Authority for use as a fuel to produce tritium for nuclear weapons, according to a public notice published in the Federal Register this week.

The project involves the Y-12 National Security Complex in Oak Ridge and Watts Bar Nuclear Plant near Spring City in Rhea County, among other sites.

The National Nuclear Security Administration and TVA announced in August that they intend to enter into an agreement to “down-blend” highly enriched uranium to low-enriched uranium in order to help produce tritium, a key “boosting” component in nuclear weapons.

The highly enriched uranium used for the “down-blending” will be processed, packaged, and shipped from Y-12, according to the NNSA. Y-12 is an NNSA site, and it is the main storage facility for certain categories of highly enriched uranium. [Read more…]

The U.S. Department of Energy’s cleanup contractor URS|CH2M Oak Ridge LLC, or UCOR, has awarded three subcontracts totaling more than $5.3 million to construct, conduct site improvements, and fabricate and install exhibits for the K-25 History Center at the East Tennessee Technology Park.

The history center will occupy 7,500 square feet in the second floor of the existing, city-owned Oak Ridge Fire Station Number 4. The building is adjacent to the K-25 Building’s 44-acre footprint, which is now part of the Manhattan Project National Historical Park. The history center will include a theater and interactive galleries that display equipment, artifacts, and other media to highlight the site’s workers and numerous Manhattan Project and Cold War-era accomplishments, a press release said.

UCOR awarded two subcontracts for construction and site improvements to North Wind Construction Services LLC of Knoxville, and it awarded a third subcontract for exhibit fabrication and installation to Formations Inc. of Portland, Oregon, the press release said. [Read more…]

Atomic Heritage Foundation launches new audio, visual program on Oak Ridge

“There was construction going on everywhere you looked,” Bill Wilcox remembered, describing his first impressions of Oak Ridge, Tennessee. “Trucks and people just crawling all over the place, hammers and banging. Wooden structures going up everywhere. Nothing was paved, and there weren’t any sidewalks.”

Wilcox was one of the thousands of people who moved to the new “Secret City” of Oak Ridge to work on the Manhattan Project, the top-secret World War II effort to develop an atomic bomb.

The Atomic Heritage Foundation has launched a new online interpretive program on Oak Ridge with 16 audio/visual vignettes. This beta program is part of AHF’s “Ranger in Your Pocket” series on the Manhattan Project, which focuses on former Manhattan Project sites and features vignettes with eyewitness accounts and expert commentary. AHF welcomes feedback and will improve and expand upon the program over the next year, a press release said.

In September 1942, Manhattan Project director General Leslie Groves designated “Site X,” approximately 59,000 acres of land on the Clinch River in rural eastern Tennessee, as the site for the project’s uranium production facilities. Approximately 3,000 people living in the area in five small farming communities were forced to leave their homes and land with minimal compensation. Construction of a new city began at breakneck speed. By the end of World War II, some 75,000 people would call Oak Ridge home, making it the fifth-largest city in Tennessee. [Read more…]

D. Ray Smith, Y-12 National Security Complex historian, received a U.S. Department of Energy Gold Medal Award on Monday for his role in helping to create the Manhattan Project National Historical Park, which includes Oak Ridge.

The award was presented to Smith by retired Lieutenant General Frank G. Klotz, DOE under secretary for nuclear security and administrator of the National Nuclear Security Administration.

Smith is retiring this month. He previously told Oak Ridge Today that he would retire November 22.

Established in November 2015, the Manhattan Project National Historical Park is a unique three-site park that includes Oak Ridge; Hanford, Washington; and Los Alamos, New Mexico. The Manhattan Project was a top-secret federal program to build the world’s first atomic weapons during World War II. Among other activities, Oak Ridge built uranium enrichment facilities for the Manhattan Project at Y-12 and the former K-25 site, and the city had the pilot facility for plutonium production at the Graphite Reactor at Oak Ridge National Laboratory, which was then known as X-10.

A $16 million contract signed by Centrus Energy Corporation and and UT-Battelle LLC will continue work on gas centrifuge uranium enrichment technology at Centrus facilities in Oak Ridge, the company announced Monday.

The work is on the AC100, a U.S. gas centrifuge uranium enrichment technology.

UT-Battelle LLC operates Oak Ridge National Laboratory for the U.S. Department of Energy.

Enriched uranium can be used in nuclear power plants and in nuclear weapons, as fuel for nuclear naval vessels, and to ensure a tritium supply, which is needed to maintain the effectiveness of America’s nuclear deterrent, officials have said previously.

The new Centrus-ORNL contract is valued at $16 million, with payments made when certain defined milestones are completed, Centrus said in a press release on Monday. The contract runs through September 30, 2018.

“Under the contract, Centrus’ scientists, engineers, and operators will test improvements developed by the company for the AC100 centrifuge machine in specialized facilities in Oak Ridge,” the press release said. “Centrus has worked under contract with ORNL since 2014 to improve the AC100 gas centrifuge technology to support national security and energy security needs.” [Read more…]

He was a passionate advocate for preserving Oak Ridge’s history.

He was known for his bow ties and captivating storytelling. He once led the effort to save the former K-25 Building in west Oak Ridge, or at least part of it.

Now the legacy of Bill Wilcox will live on at the K-25 History Center.

Construction on the history center could start early next year on the second floor of Oak Ridge Fire Station Number Four. That fire station, previously transferred to the city, is on the south side of the former K-25 Building at East Tennessee Technology Park in west Oak Ridge.

Officials preparing for the construction of the history center gave tours of its future home at the fire station on Thursday. The tours followed a lunchtime celebration that featured tributes to Wilcox and included speeches and presentations by U.S. Department of Energy and Oak Ridge officials, and federal contractors and historic preservation advocates. Wilcox was hailed as the “father of K-25 historic preservation.”

“He would have been really proud,” said Ray Smith, Wilcox’s friend and Y-12 National Security Complex historian and city historian. “His legacy lives on.” [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 Friday, July 28.

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.
