Radioactive waste is a type of hazardous waste that contains radioactive material. Radioactive waste is a result of many activities, including nuclear medicine, nuclear research, nuclear power generation, nuclear decommissioning, rare-earth mining, and nuclear weapons reprocessing. The storage and disposal of radioactive waste is regulated by government agencies in order to protect human health and the environment.
The Hanford Site is a decommissioned nuclear production complex operated by the United States federal government on the Columbia River in Benton County in the U.S. state of Washington. It has also been known as Site W and the Hanford Nuclear Reservation. Established in 1943 as part of the Manhattan Project, the site was home to the Hanford Engineer Works and B Reactor, the first full-scale plutonium production reactor in the world. Plutonium manufactured at the site was used in the first atomic bomb, which was tested in the Trinity nuclear test, and in the Fat Man bomb used in the bombing of Nagasaki.
Richland is a city in Benton County, Washington, United States. It is located in southeastern Washington at the confluence of the Yakima and the Columbia Rivers. As of the 2020 census, the city's population was 60,560. Along with the nearby cities of Pasco and Kennewick, Richland is one of the Tri-Cities, and is home to the Hanford nuclear site.
Columbia Generating Station is a nuclear commercial energy facility located on the Hanford Site, 10 miles (16 km) north of Richland, Washington. It is owned and operated by Energy Northwest, a Washington state, not-for-profit joint operating agency. Licensed by the Nuclear Regulatory Commission in 1983, Columbia first produced electricity in May 1984, and entered commercial operation in December 1984.
The B Reactor at the Hanford Site, near Richland, Washington, was the first large-scale nuclear reactor ever built. The project was a key part of the Manhattan Project, the United States nuclear weapons development program during World War II. Its purpose was to convert natural uranium metal into plutonium-239 by neutron activation, as plutonium is simpler to chemically separate from spent fuel assemblies, for use in nuclear weapons, than it is to isotopically enrich uranium into weapon-grade material. The B reactor was fueled with metallic natural uranium, graphite moderated, and water-cooled. It has been designated a U.S. National Historic Landmark since August 19, 2008 and in July 2011 the National Park Service recommended that the B Reactor be included in the Manhattan Project National Historical Park commemorating the Manhattan Project. Visitors can take a tour of the reactor by advance reservation.
PUREX is a chemical method used to purify fuel for nuclear reactors or nuclear weapons. PUREX is the de facto standard aqueous nuclear reprocessing method for the recovery of uranium and plutonium from used nuclear fuel. It is based on liquid–liquid extraction ion-exchange.
The Metallurgical Laboratory was a scientific laboratory at the University of Chicago that was established in February 1942 to study and use the newly discovered chemical element plutonium. It researched plutonium's chemistry and metallurgy, designed the world's first nuclear reactors to produce it, and developed chemical processes to separate it from other elements. In August 1942 the lab's chemical section was the first to chemically separate a weighable sample of plutonium, and on 2 December 1942, the Met Lab produced the first controlled nuclear chain reaction, in the reactor Chicago Pile-1, which was constructed under the stands of the university's old football stadium, Stagg Field.
Uranium-233 is a fissile isotope of uranium that is bred from thorium-232 as part of the thorium fuel cycle. Uranium-233 was investigated for use in nuclear weapons and as a reactor fuel. It has been used successfully in experimental nuclear reactors and has been proposed for much wider use as a nuclear fuel. It has a half-life of 160,000 years.
Downwinders were individuals and communities in the intermountain between the Cascade and Rocky Mountain ranges primarily in Arizona, Nevada, New Mexico and Utah but also in Oregon, Washington, and Idaho who were exposed to radioactive contamination or nuclear fallout from atmospheric or underground nuclear weapons testing, and nuclear accidents.
Since the mid-20th century, plutonium in the environment has been primarily produced by human activity. The first plants to produce plutonium for use in cold war atomic bombs were at the Hanford nuclear site, in Washington, and Mayak nuclear plant, in Chelyabinsk Oblast, Russia. Over a period of four decades, "both released more than 200 million curies of radioactive isotopes into the surrounding environment – twice the amount expelled in the Chernobyl disaster in each instance".
Atomic tourism or nuclear tourism is a recent form of tourism in which visitors learn about the Atomic Age by traveling to significant sites in atomic history such as nuclear test reactors, museums with nuclear weapon artifacts, delivery vehicles, sites where atomic weapons were detonated, and nuclear power plants.
Plutonium is a radioactive chemical element with the symbol Pu and atomic number 94. It is an actinide metal of silvery-gray appearance that tarnishes when exposed to air, and forms a dull coating when oxidized. The element normally exhibits six allotropes and four oxidation states. It reacts with carbon, halogens, nitrogen, silicon, and hydrogen. When exposed to moist air, it forms oxides and hydrides that can expand the sample up to 70% in volume, which in turn flake off as a powder that is pyrophoric. It is radioactive and can accumulate in bones, which makes the handling of plutonium dangerous.
The Atomic Heritage Foundation (AHF) is a nonprofit organization originally based in Washington, DC, dedicated to the preservation and interpretation of the Manhattan Project, the Atomic Age, and its legacy. Founded by Cynthia Kelly in 2002, the Foundation's stated goal is, "to provide the public not only a better understanding of the past but also a basis for addressing scientific, technical, political, social and ethical issues of the 21st century." AHF works with Congress, the Department of Energy, the National Park Service, state and local governments, nonprofit organizations and the former Manhattan Project communities to preserve and interpret historic sites and develop useful and accessible educational materials for veterans, teachers, and the general public. In June 2019, the Atomic Heritage Foundation and the National Museum of Nuclear Science & History signed an agreement that granted stewardship of the Atomic Heritage Foundation website and all of the AHF's physical collections to the museum. The Atomic Heritage Foundation website is now run by the National Museum of Nuclear Science & History. Additionally, the museum now houses the Atomic Heritage Foundation's physical collections which have been integrated into the Nuclear Museum's own collection.
The bismuth-phosphate process was used to extract plutonium from irradiated uranium taken from nuclear reactors. It was developed during World War II by Stanley G. Thompson, a chemist working for the Manhattan Project at the University of California, Berkeley. This process was used to produce plutonium at the Hanford Site. Plutonium was used in the atomic bomb that was used in the atomic bombing of Nagasaki in August 1945. The process was superseded in the 1950s by the REDOX and PUREX processes.
These are lists of nuclear disasters and radioactive incidents.
James Leroy Acord was an artist who worked directly with radioactive materials. He attempted to create sculpture and events that probed the history of nuclear engineering and asked questions about the long-term storage of nuclear waste. For 15 years he lived in Richland, Washington, the dormitory town for the Hanford Nuclear Reservation, at one time home to nine nuclear reactors and five plutonium-processing complexes and the most contaminated nuclear site in the United States. His major ambition while there was to build a "nuclear Stonehenge" on a heavily contaminated area of land in the site, incorporating twelve uranium breeder-blanket assemblies.

Nuclear labor issues exist within the international nuclear power industry and the nuclear weapons production sector worldwide, impacting upon the lives and health of laborers, itinerant workers and their families.
The More Hall Annex, formerly the Nuclear Reactor Building, was a building on the campus of the University of Washington (UW) in Seattle, Washington, United States, that once housed a functional nuclear research reactor. It was inaugurated in 1961 and shut down in 1988, operating at a peak of 100 kilowatts thermal (kWt), and was officially decommissioned in 2007.
The Hanford Engineer Works (HEW) was a nuclear production complex established by the United States federal government in 1943 as part of the Manhattan Project during World War II. Located at the Hanford Site on the Columbia River in Benton County, Washington state, it was home to the B Reactor, the first full-scale plutonium production reactor. Plutonium was a synthetic element that had only recently been isolated in the laboratory, but it was theorized that it could be produced by the irradiation of uranium in a nuclear reactor. Plutonium manufactured at the HEW was used in the first atomic bomb in the Trinity test, and then in the Fat Man bomb that was used in the atomic bombing of Nagasaki in August 1945. It was commanded by Colonel Franklin T. Matthias until January 1946, and then by Colonel Frederick J. Clarke.
