The Manhattan Project and Its Legacy
The Manhattan Project was a massive project that spanned several countries and was aimed at creating nuclear weapons. It was run by the US Department of Energy and was primarily located in Oak Ridge, Tennessee and Los Alamos, New Mexico. While the Manhattan Project ended in 1945, the legacy it left behind is still felt today.
Los Alamos National Laboratory
Los Alamos National Laboratory is a federal research laboratory that continues to play an important role in cutting-edge work in nuclear physics and space exploration. This facility, which resides on a former college prep ranch in New Mexico, was the location for the Manhattan Project, a United States initiative to create the world’s first atomic bomb. The research conducted at this facility helped develop several of the world’s most famous bombs, including the atomic bombs dropped on Japan in 1945 and on Nagasaki in 1950. Today, the facilities at Los Alamos are a National Historic Landmark.
During the height of the Manhattan Project, the Los Alamos National Laboratory was a place where the world’s greatest scientists came together to develop the world’s first atomic bomb. Scientists included explosive experts, metallurgists, physicists and computer engineers. They worked to design and test the bombs.
Los Alamos was originally planned as a military research laboratory. General Leslie Groves, who led the Manhattan Project, selected Los Alamos as the site for the top-secret design and production of the atomic bomb. He was inspired by the beauty of the area and wanted to locate a bomb-production facility there. Oppenheimer, who was the director of the Los Alamos Laboratory, convinced Groves to use the ranch. In addition to choosing the site, he recruited a number of scientists to work at the laboratory.
While the main goal of the Los Alamos Laboratory was to conduct research related to the development of atomic weapons, the facility also performed a number of other scientific endeavors. Researches on renewable energy and other areas of science were conducted. Some of the more notable discoveries made at the lab include early flow cytometry technology and the creation of an HIV vaccine.
Thousands of people worked at the laboratory. They were divided into three sections: military, scientists, and administrative personnel. As the project progressed, the need for security increased. Consequently, the Los Alamos Army was formed to provide security for the laboratory. It would maintain a secure post for the scientists and the military. However, it was unclear how the researchers could communicate.
After World War II, the government created a second lab, called Lawrence Livermore, to complement the research at Los Alamos. Livermore became an informal competitor to Los Alamos. The United States spent approximately $9 billion to build a decade of work at both sites.
In the aftermath of the cold war, Los Alamos focused on other areas of science. Scientists at the lab developed bio-detectors, detectors to stop terrorists, and computer code to improve automobile efficiency. Researchers at the lab also created a virus database that may be useful in the development of an AIDS vaccine. Other researchers at the lab studied cancer, breast cancer, and ovarian cancer.
Oak Ridge, Tennessee
Oak Ridge, Tennessee is not well known, but it is one of the key cities involved in the making of the atomic bomb. It was not the first place to be used to create nuclear weapons, but it played a major role in the development of the world’s first bomb.
The Manhattan Project was designed to produce the atomic bomb by introducing the gaseous diffusion method to enrich uranium. It was during this time that the United States began building gigantic plants that would make the bomb possible. In Oak Ridge, Tennessee, workers built the largest uranium enrichment plant in the world, called the K-25 Plant. The name comes from the Kellex Corporation, which was a prime contractor for the project.
The Manhattan Project was a complex undertaking, but the most impressive feat was the invention of the gaseous diffusion method. The United States was also responsible for establishing several other successful methods of uranium enrichment. The X-10 Graphite Reactor in Oak Ridge, Tennessee was one of the few surviving buildings from the project.
As a part of the Manhattan Project, the United States constructed two massive uranium enrichment plants, the K-25 Plant and S-50, which was an experimental plutonium plant. A third site, the Oak Ridge reservation, served as the military headquarters for the project. There were uranium processing, smelting, and enrichment facilities on the reservation. Many of these sites are now under the stewardship of the National Park Service.
When the Manhattan Project began construction, the town of Oak Ridge was built as a planned community. At its beginning, it was a sleepy little town that had about seven hundred inhabitants. By 1945, it was a booming town of nearly 75,000.
The atomic bomb was a significant accomplishment for the United States, but the Manhattan Project was a much bigger undertaking than its creators were ready to admit. Workers were exposed to dangerous levels of radiation, and an abnormal number of former employees developed chronic illnesses after the work was completed. Despite these challenges, the Manhattan Project was able to develop a nuclear weapon that was later tested in August 1945.
Oak Ridge, Tennessee was the site of the world’s first atomic bomb, which was dropped on the Japanese city of Hiroshima. Although the United States won the race against Nazi Germany to develop the atomic bomb, the residents of Oak Ridge didn’t realize their contributions until the bomb was dropped.
Another prominent milestone was the establishment of the Manhattan Project Heritage Park, a new national park that preserves the World War II-era sites and stories of the Manhattan Project. Visitors to the park will be able to see a working atomic bomb and learn about the many women who were integral to the era.
Hanford, Washington
During World War II, the US government established the Hanford Site as a part of the Manhattan Project. This project involved the development of nuclear weapons. The US was competing with Germany in the atomic bomb race, and the Manhattan Project was a secret program. The site was located on the southern shore of the Columbia River.
Originally, the Hanford Site was a farming community. In the mid-1800s, the area began to be settled by pioneers. Its location was advantageous as the Columbia River provided hydroelectric power. A few small towns were established to support the early residents.
Hanford was selected as the site for the Manhattan Project because of its proximity to the Columbia River and its history as a farming town. However, the project posed a serious risk to the local environment. Early waste disposal methods resulted in a significant amount of radioactive materials being released into the air and water. As the project’s production processes became more efficient, these liquid wastes were eventually stored underground.
In 1943, construction at the Hanford Nuclear Reservation began. This included two chemical separations complexes, a construction camp, an employee village, and the construction of three reactor complexes. Total construction took thirty months.
Eventually, the project expanded to include five plutonium-processing complexes. At that time, the Site employed about 51,000 people. Those workers were often required to handle toxic materials with their bare hands. Ultimately, the Site produced two-thirds of the plutonium used in US nuclear weapons stockpile.
The B Reactor at Hanford was the first large-scale nuclear reactor built. It was designed to produce plutonium for the first atomic bomb. While its operation ended in 1990, the reactor is still preserved and is a National Historic Landmark. Since 2009, tours of the reactor have been offered to the public.
Currently, the Site is managed by two Department of Energy offices. The primary focus of this work is the cleanup of radioactive waste from the Manhattan Project. The Department of Energy website provides information on the project and the cleanup process.
When the Department of Energy (DOE) signed a Tri-Party Agreement with the state of Washington and the Environmental Protection Agency (EPA), the cleanup was set in motion. Among other things, the agreement laid the groundwork for the Hanford Thyroid Disease Study and lays the groundwork for the disposal of radioactive waste.
To date, the Site has exposed over 1,700 waste sites and 500 contaminated buildings to radiation. Crews have used several strategies to decontaminate the soil and groundwater. There are also burial sites at the Site.
The Hanford Site has become the largest environmental cleanup in U.S. history. For decades, the area was contaminated with hazardous radioactive materials. Throughout the Site, remnants of Native American activity are visible.
