Portal:Nuclear technology/Pictures/46 Credit: Federal government of the United States "TRINITY PHOTOGRAPH - Alamogordo, NM - Trinity test , July 16, 1945 - "JUMBO," a 120-ton steel vessel, was designed to contain the explosion of the bomb's high explosive and permit recovery of the active material in case on nuclear failure."
The B Reactor had its first nuclear chain reaction in September 1944, the D Reactor in December 1944 and the F Reactor in February 1945. The initial operation was halted by a problem identified as neutron absorption by the fission product Xe-135 , first identified in a research paper of Chien-Shiung Wu that was shared with Fermi.

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.
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 ...
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.
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 ...
The plutonium produced at B Reactor powered the first man-made atomic explosion, the Trinity test, in the New Mexico desert in July 1945 and weeks later the atomic bomb dropped on Nagasaki, Japan ...
