The B Reactor at the Hanford Site, near Richland, Washington, was the first large-scale nuclear reactor ever built, at 250 MWth. It achieved criticality on September 26, 1944. It achieved criticality on September 26, 1944.
Construction on B Reactor commenced in August 1943 and was completed on September 13, 1944. The reactor went critical in late September and, after overcoming neutron poisoning, produced its first plutonium on November 6, 1944. [58] The reactors were graphite moderated and water cooled. They consisted of a 28-by-36-foot (8.5 by 11.0 m), 1,200 ...
B Reactor produced the plutonium that powered the first man-made atomic explosion, the Trinity test, in the New Mexico desert in July 1945. Weeks later, the atomic bomb dropped on Nagasaki, Japan ...
Hanford’s B Reactor, the world’s first full-scale production reactor, is shown from the air in 1944. B Reactor also produced plutonium for the atomic bomb dropped on Nagasaki, Japan, Aug. 9 ...
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. It built and operated the B Reactor, the first full-scale plutonium production reactor.
Hanford’s historic B Reactor, the world’s first full-scale nuclear reactor, went critical on Sept. 26, 1944. Wigner’s team had designed the Hanford reactors to house 1,600 process tubes.
