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.

The U.S. Department of Energy is requesting more time to complete projects to commemorate the historic contributions of the former K-25 site in west Oak Ridge.

Built during World War II, the K-25 site helped enrich uranium for the first atomic bomb used in wartime as part of the top-secret Manhattan Project. The plant continued to enrich uranium for nuclear weapons and commercial nuclear power plants after the war, and those who have worked at the site have said it helped win the Cold War.

The history of the site will be honored by preserving the concrete slab of the former K-25 Building, building a Viewing Tower and replica Equipment Building on the south side of the building site, and opening a K-25 History Center on the second floor of the adjacent Oak Ridge Fire Station Number 4.

A historical interpretation agreement was signed in August 2012. But it expires this August. And the roughly $20 million worth of projects won’t be complete by then.

DOE is making “good progress,” but “the reality is we need a little more time,” said Dave Adler, acting deputy manager for DOE’s Oak Ridge Office of Environmental Management. Adler and Steve Cooke, K-25 preservation coordinator for DOE, briefly discussed the proposed amendment to the agreement during a Tuesday evening work session with the Oak Ridge City Council.

Council, DOE to discuss proposed amendment to historical interpretation agreement

Posted at 2:33 pm February 17, 2019

The Oak Ridge City Council and U.S. Department of Energy will discuss a proposed amendment to a historical interpretation agreement on Tuesday evening.

The agenda for the non-voting Council work session does not give the purpose of the proposed amendment or say what it might do.

But it appears that the proposed amendment could be related to historical interpretation at the former K-25 site in west Oak Ridge because one of the DOE representatives scheduled to talk to Council is Steve Cooke, K-25 preservation coordinator for the U.S. Department of Energy. Also scheduled to talk to Council is Dave Adler, acting deputy manager for DOE’s Oak Ridge Office of Environmental Management. [Read more…]

K-25 Equipment Building & Viewing Tower: Design complete, construction funding available

The design is complete and funding is available for the construction of an Equipment Building and Viewing Tower that will help commemorate the history of the K-25 Building, once the world’s largest building under one roof.

K-25 was built in Oak Ridge during World War II to help enrich uranium for the Manhattan Project. That was a top-secret federal program to build the world’s first atomic weapons. During the war, Oak Ridge enriched the uranium for “Little Boy,” the first atomic bomb used in wartime. “Little Boy” was detonated over Hiroshima, Japan, on August 6, 1945, shortly before the end of World War II.

After the war, the four-story, 44-acre K-25 Building and four other large buildings at the K-25 site continued to use a process known as gaseous diffusion to enrich uranium for atomic weapons and commercial nuclear power plants. Officials say the K-25 site, which is in west Oak Ridge, helped win the Cold War.

After decades of use, the K-25 site was shut down in the mid-1980s, and as part of a cleanup effort in recent years, the five large gaseous diffusion buildings have been demolished. But the history of the K-25 building and the site will live on in a History Center on the second floor of Oak Ridge Fire Station Number 4, which is next to K-25’s concrete slab, and at the Equipment Building and Viewing Tower, which will be just west of the History Center.

The History Center, Equipment Building, and Viewing Tower will be on the south side of the former K-25 Building. The site is now known as Heritage Center or East Tennessee Technology Park. [Read more…]

We’ve been thinking recently that maybe we should run an occasional feature called “Did you know?” on Oak Ridge Today that would highlight interesting facts about Oak Ridge that might not be widely known. This could be information that makes the city unique or unusual, but doesn’t normally fit into a news story. Many of these could be history-related facts, but they wouldn’t all have to be.

Here’s an example from the K-25 History Center unveiling celebration last week:

Did you know that the Wheat community in what is now west Oak Ridge was once famous for its peach orchards? The peaches were sold across the country, according to Mick Wiest, president of the Oak Ridge Heritage and Preservation Association.

Besides its peaches, Wheat was also famous for its schools and education, Wiest said during a Thursday ceremony for the K-25 History Center at the East Tennessee Technology Park, the former K-25 site. [Read more…]

Once like a small city, Happy Valley has been sold

It was once home to a large construction camp that was like a small city and housed workers building K-25 during World War II.

Now the 160-acre parcel known as Happy Valley has been sold.

Happy Valley was in west Oak Ridge, across State Route 58 from the K-25 site. One of three major sites in Oak Ridge, K-25 was built to enrich uranium for atomic weapons as part of the top-secret Manhattan Project during World War II.

Today, Happy Valley appears to be mostly a rolling tree-covered landscape between Oak Ridge and Kingston along SR 58. To the public, there is little or no obvious evidence of what was once there—homes, a grocery store, schools, a post office, recreation halls, a gas station, and a bowling alley.

But those who have walked the property have seen evidence of the small city that was once there. [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…]

The public is invited to walk through the future home of the K-25 History Center on Thursday, October 19.

The K-25 History Center will be built on the second floor of Oak Ridge’s Fire Station Number 4. The fire station is at East Tennessee Technology Park, the former K-25 site in west Oak Ridge.

The public walk-through is scheduled from 2-4 p.m. October 19.

The K-25 History Center is expected to help preserve the history of the World War II-era Manhattan Project. Oak Ridge was built during that top-secret project to help build the world’s first atomic weapons.

K-25 was one of three major federal sites built in the city that is now Oak Ridge as part of the Manhattan Project. [Read more…]

City wants to renovate fire station as DOE, contractors work on K-25 History Center

Oak Ridge wants to renovate the fire station where the federal government and its contractors are building the K-25 History Center, a project that is expected to help preserve the history of the World War II-era Manhattan Project.

The K-25 History Center will be built on the second floor of Oak Ridge’s Fire Station Number 4. The fire station is at East Tennessee Technology Park, the former K-25 site in west Oak Ridge.

K-25 was one of three major federal sites built in Oak Ridge during World War II as part of the top-secret Manhattan Project. That was a federal program to build the world’s first atomic weapons, before Germany could.

K-25’s signature facility, the K-25 Building, has been demolished. But a 2012 agreement that allowed the complete demolition of that building, once the world’s largest building under one roof, called for the history center at the fire station, among other projects.

Work is proceeding on the K-25 History Center, Oak Ridge Fire Chief Darryl Kerley said in a July 21 memo to City Manager Mark Watson. The K-25 History Center is a project of the U.S. Department of Energy and UCOR, DOE’s cleanup contractor in Oak Ridge.

As that project proceeds, several upgrades will be needed to the first floor of the city-owned fire station in order to create the required living space for fire department personnel, Kerley said. [Read more…]
