Two federal agencies have agreed to build a K-25 Viewing Platform at the historic site in west Oak Ridge that was used to enrich uranium for nuclear weapons and nuclear power plants during World War II and the Cold War. The design is expected to be complete in March and the building completed by the end of 2023.

The construction agreement for the viewing building at the former K-25 site was signed by the U.S. Department of Energy’s Oak Ridge Office of Environmental Management and U.S. Army Corps of Engineers.

The viewing platform will give visitors a view of the large 44-acre footprint of the former K-25 Building. K-25, which was the world’s largest building, was erected during World War II as part of the Manhattan Project to help enrich uranium for the world’s first atomic bombs during World War II. The K-25 Building was demolished in 2013, and many other structures at the site have been removed as the federal government turns over property for private development.

The K-25 Building site itself is now part of the Manhattan Project National Historical Park. That project commemorates the workers, equipment, and processes used during the Manhattan Project in Oak Ridge, Tennessee; Hanford, Washington; and Los Alamos, New Mexico.

The K-25 Viewing Platform and associated exhibits are the final components of a multi-project agreement that the Oak Ridge Office of Environmental Management signed in 2012, clearing the way for demolition of the North Tower of the mile-long, U-shaped K-25 Building. The projects commemorate the history of the K-25 site, which has also been known as the Oak Ridge Gaseous Diffusion Plant.

The Manhattan Project National Historical Park will ring the International Friendship Bell 76 times on Friday morning, August 6, to commemorate the effects of the atomic bombing of Hiroshima 76 years ago.

The bomb was dropped on Hiroshima, Japan, at 8:15 a.m. on August 6, 1945. It was the first atomic bomb used in war and the first of two dropped on Japan near the end of World War II. Uranium for the first bomb, which was code-named “Little Boy,” was enriched in Oak Ridge. The bomb had about 140 pounds of uranium fuel and had an explosive force equivalent to 15,000 tons of TNT, according to Atomic Heritage. Between 90,000 and 166,000 people are believed to have died from the 10-foot, 9,700-pound bomb in the four-month period following the explosion, Atomic Heritage said.

The National Park Service is calling the August 6 ceremony “Days of Peace and Remembrance.”

“During this silent event, we will be requesting visitors to come up and ring the bell,” a press release said. “Visitors will be able to write down their own hopes and messages of peace.”

The United States dropped a second atomic bomb, a plutonium-fueled weapon, on Nagasaki, Japan, on August 9, 1945, three days after the Hiroshima bombing. It had about 13.6 pounds of plutonium fuel and an explosive force equivalent to 21,000 tons of TNT. About 80,000 Japanese died by the end of 1945 because of that bomb, which was called “Fat Man,” Atomic Heritage said.

You can paddle back in time to visit the historic Freels Bend Cabin and enjoy the beauty of the Clinch River this evening (Thursday, July 8) in Oak Ridge, a press release said.

Participants will learn more about the Manhattan Project as well as its impact on Oak Ridge and the surrounding areas, the press release said. The Manhattan Project was a top-secret federal program to build the world’s first atomic weapons during World War II. Oak Ridge was part of the project. Only a few pre-war structures remain in the city, including Freels Bend Cabin.

“Together, we will visit the cabin, which was built and then remodeled during the 1800s by the Freels family of Anderson County,” said the press release from the National Park Service. “It has maintained its historical significance all these years and now resides on Department of Energy property.”

You can learn about Wheat, a community before World War II, during a walk in west Oak Ridge on Saturday.

The walk will be led by a National Park Service ranger starting at 10 a.m. Saturday, June 5. The program will begin at Blair Road and the North Boundary Greenway.

Wheat was a community that existed in what is now west Oak Ridge before the city was built as part of the top-secret Manhattan Project during World War II. That was a federal program to build the world’s first atomic weapons, before Germany could.

Oak Ridge is one of three sites that are part of the Manhattan Project National Historical Park. The other two are Hanford, Washington, and Los Alamos, New Mexico.

The visitor center for the Manhattan Project National Historical Park in Oak Ridge re-opened on Tuesday.

The visitor center had been shut down for many months because of the COVID-19 pandemic.

The visitor center is at the Children’s Museum of Oak Ridge on West Outer Drive. It is open Tuesday through Saturday from 10 a.m. to 4 p.m., and from 1 p.m. to 4 p.m. on Sundays.

Oak Ridge is one of three sites that are part of the Manhattan Project National Historical Park. The other two are Hanford, Washington, and Los Alamos, New Mexico. All three were part of the top-secret Manhattan Project during World War II. That was a federal program to build the world’s first atomic bombs, before Germany could. The park tells the story of the workers and their missions during and after the war.

After a long shutdown during the COVID-19 pandemic, the K-25 History Center re-opened Monday morning.

The K-25 History Center is located on the south side of the site where the K-25 Building used to be at what is now Heritage Center in west Oak Ridge. The K-25 Building was once the world’s largest. The K-25 History Center is on the second floor of the City of Oak Ridge fire station at Heritage Center.

The K-25 site was built during World War II, and it enriched uranium for nuclear weapons and commercial nuclear power plants. The site was shut down in the 1980s. The site was built as part of the top-secret Manhattan Project, and it was to help enrich uranium for the world’s first atomic bombs during World War II.

Demolition work at a former radioisotope laboratory in Oak Ridge could be complete this spring.

The U.S. Department of Energy Oak Ridge Office of Environmental Management and UCOR announced earlier this year that UCOR, a contractor, had begun removing the two remaining structures at the former Radioisotope Development Lab at Oak Ridge National Laboratory.

“This project launches our next phase of major demolition and cleanup at ORNL,” said Nathan Felosi, OREM’s portfolio federal project director for ORNL. “Our work is eliminating contaminated structures, like this one, that are on DOE’s list of high-risk facilities and clearing space for future research missions.”

Known as “hot cells,” the structures being demolished are heavily shielded concrete rooms that provided researchers protection from highly radioactive material during the years the laboratory was operational, a press release said.

An undated aerial photo posted online by the U.S. Department of Energy Oak Ridge Office of Environmental Management shows the former K-25 Building, once the world’s largest building, in west Oak Ridge. The building has been demolished, but its history is being preserved, including at the new K-25 History Center.

The National Park Service is asking for public comments about the Manhattan Project National Historical Park. The comments are being sought as the Park Service prepares an interpretive plan for park programming, exhibits, and media, a press release said. The goal is to capture many different experiences and perspectives.

Discussions with the public are being organized by theme and region. The discussions focused on regions concentrate on the areas around the three Manhattan Project park locations: Hanford, Washington; Los Alamos, New Mexico, and Oak Ridge, Tennessee. Because of COVID-19, all events will be held virtually (online), the press release said.

The public meetings are Tuesday to Thursday this week. Here is the schedule:

More than 1,000 protest for equality, police reforms, end of racism

More than 1,000 people marched and protested in Oak Ridge last week, asking for equal treatment for black people.

They said the nation is obligated to fight systemic racism, racial inequality, and police brutality. They want to live without fear. They advocated for police reforms, accountability, and the use of de-escalation tactics.

Protesters hope to end 400 years of oppression that started with slavery in America in 1619 and continued after the Civil War with attacks on black people, lynchings, the Ku Klux Klan, segregation, discrimination, and racism. That oppression has been felt in Oak Ridge, and some young adults and teenagers said they have experienced or witnessed racism.

Protesters said they were angry, upset, and frustrated. They called the death of George Floyd while he was detained by police in Minneapolis last month a murder. They recalled the deaths of other black men and boys, some killed by police and others by citizens. They acknowledged that there are many good police officers, but they condemned police officers who they said hide behind their badges to do wicked deeds.

“Enough is enough,” protesters said. “We are done dying.”

Protesters met at Oak Ridge High School Tuesday afternoon, June 2, and marched to the Oak Ridge Civic Center. They carried signs and wore T-shirts that said “Black Lives Matter” and “I can’t breathe.” They chanted “No justice, no peace” and, led by organizer Trevor King, “Make racism illegal.” Silence is compliance, the protesters said, and silence in the face of evil is itself evil.

Built before the war, this home is for sale

A home in east Oak Ridge that was built before World War II is for sale. It’s one of the few structures that was built before the war and remains in the city today.

The Luther Brannon House is at 151 Oak Ridge Turnpike, just west of Melton Lake Drive and next to the U.S. Department of Energy’s Office of Scientific and Technical Information. It’s listed on the National Register of Historic Places, and it was the first home in Oak Ridge to be privately owned.

The single-story stone bungalow was built by Owen Hackworth in 1941 and soon acquired by the federal government as part of the top-secret Manhattan Project during World War II. Hackworth was a longtime resident of the Clinch River Valley.

Don Raby provided Oak Ridge Today with early photographs of the home after a fire damaged the house in 2014. It’s not clear how extensive the damage was or if repairs have been made.

Raby has collected photographs of the original structures that were here before the Manhattan Project, when the “secret city” that is now Oak Ridge helped build the world’s first atomic bombs. The 59,000-acre military reservation, which replaced several rural communities, was known first as Kingston Demolition Range and then as Clinton Engineer Works.
