The N-Reactor at the Hanford site along the Columbia River. Aerial Photo of the N-Reactor. Taken January 2013. Fuel element from N-Reactor. The N-Reactor was a water/graphite-moderated nuclear reactor constructed during the Cold War and operated by the U.S. government at the Hanford Site in Washington; it began production in 1963.
Plutonium could be produced by irradiating uranium-238 in a nuclear reactor, [4] but developing and building a reactor was a task for the Manhattan Project physicists. The task for the chemists was to develop a process to separate plutonium from the other fission products produced in the reactor, to do so on an industrial scale at a time when plutonium could be produced only in microscopic ...
The Hanford Site occupies 586 square miles (1,518 km 2) – roughly equivalent to half the total area of Rhode Island – within Benton County, Washington. [1] [2] It is a desert environment receiving less than ten inches (250 mm) of annual precipitation, covered mostly by shrub-steppe vegetation.
The Hanford melters use temporary heaters at startup and then a second set of heaters are turned on. These are joule heaters that pass an electrical current through the pool of melted glass.

B Reactor and water treatment area in 1944. The Hanford Engineer Works (HEW) was a nuclear production complex in Benton County, Washington, established by the United States federal government in 1943 as part of the Manhattan Project during World War II.
Radioactive contamination can be due to a variety of causes. It may occur due to the release of radioactive gases, liquids or particles. For example, if a radionuclide used in nuclear medicine is spilled (accidentally or, as in the case of the Goiânia accident, through ignorance), the material could be spread by people as they walk around.
