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 .
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 ...
Just four months earlier, operators had started Hanford’s B Reactor for the first time on Sept. 26, 1944. The moment came after 13 months of furious effort. Fifty years ago Friday, on Aug. 27 ...
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.
The B Reactor at the Hanford site was the world’s first full-scale nuclear reactor. Here, scientists and engineers pioneered the technology behind nuclear reactors.
On September 26, the B Reactor is started at Hanford Site, Washington. At 250 MWth, it is the first reactor to exceed 10 and 100 MWth and is considered the first large-scale reactor . The site is primarily built for weapons-grade plutonium production, but also produces weapons-usable tritium , polonium-210 , and uranium-233 , as well as non ...
