Oak Ridge may no longer be a secret city, but if you're looking for a place important in American history, it's worth exploring. Oak Ridge was built during World War II as a complete city for workers at the Clinton Engineer Works (CEW) and was the site of the Manhattan project that led to the construction of one of America's largest nuclear power plants. The technology developed at Oak First formed the foundation on which the huge plutonium production plant at Hanford is based. It is the birthplace of nuclear energy, the world's first nuclear reactor and an important contribution to the development of modern nuclear weapons.

Some parts of the Oak Ridge complex are still in use and you can still see the people who originally brought everything to its current state. Four plants used to make material for the atomic bomb survived and have been fully used since the Cold War. One of them, Oak First, provides the facility that enriches uranium for use in nuclear power plants in the United States and around the world.

It is reported that 90 percent of the building is still in use in the city and is within 30 minutes of the city centre, as it is today. Along this route, a Tennessee Valley Authority substation from the 1940s can be seen, which helped generate the enormous amount of electricity the plant needs.

The East Tennessee Technology Park, Gov. Bill Lee said, hopes to serve as a catalyst for the next phase of development in Oak Ridge, including the construction of a new downtown and expansion of downtown. Some of the area has an airport, and Oak Ridge is the largest city in Tennessee that does not have an airport.

Visitors can drop by to learn more about the history of Oak Ridge and the Manhattan Project and its impact on the US government. A complete list of scientists who have worked there can be obtained by purchasing a copy of "A Guide to the Hehattan Project in Tennessee," available from the National Archives and Records Administration in Washington, D.C.

Visitors to Oak Ridge should start their journey at the American Museum of Science and Energy, which offers a wonderful overview of the city's wartime past. The walk is set in a beautiful garden and is a memorial to the people who came to Oak Ridge during the war. The memorial features 10 bronze plaques explaining the history of Oak Oak Grove and the Manhattan Project and its impact on the United States.

In 1948, the Oak Ridge National Laboratory established a facility codenamed X-10, which extracted plutonium from irradiated uranium screws and contained the original graphite reactor. The guide shows you what it looked like in the 2 million square meter facility used for uranium enrichment by gaseous diffusion.

In addition, the X-10 uranium enrichment facility at Oak Ridge National Laboratory was guarded by the US Army Corps of Engineers and the United States Atomic Energy Commission for about 75 years.

In 1944, the two-year-old city had about 2,000 residents, about half of them residents, but by 1947, when the Atomic Energy Commission took direct control of the project, the population had fallen to 40,000. The 1950 census showed that Oak Ridge was still the fifth largest city in the state, and there were also more than 1,500 residents in Knoxville, Knox County, Tennessee. That is equivalent to a population of about 1.5 million people today, which is a remarkable achievement. I've visited contaminated departments of the Department of Energy across the country and I've been told that here in Oak First, we're doing things differently, "said Dr. Robert E. Smith, a nuclear engineering professor at the University of Tennessee at Chattanooga.

To ensure that our clean-up efforts meet Tennessee and federal environmental standards, we play a key role in protecting the health and safety of people in Oak Ridge, Knoxville and Knox County. It monitors and reaches the local community as well as federal, state and local authorities. Chapel on the Hill is a beautiful wooden chapel in Oak Hill, Tennessee that served as Tennessee's primary church during the Manhattan Project.

Back then, it wasn't called Oak Ridge, but Site X, or Clinton Engineering Works.

Although the K-25 was located just 11 miles from the headquarters in Oak Ridge, it was designed as a satellite city. The residents of the town called Happy Valley "Happy Valley" and had similar living conditions to those in Oak But Ridge also experienced chronic shortages at the headquarters. Those who did not live in or near the oak ridge had to be trapped from a distance of more than 50 miles.

When President Roosevelt approved the Manhattan Project on December 28, 1942, work was already underway on the East Tennessee site where the first production facility was to be built. Tennessee Eastman raced to complete the trial so that training and testing could be conducted at Oak Ridge. A quick analysis showed that the thermal diffusion plant was actually built at Oak Ridge and commissioned in early 1945. To get the project on track, Tennessee Eastman had to race against the clock to complete the plant by the end of the year.
