K-25

K-25 was the codename given by the Manhattan Project to the program to produce enriched uranium for atomic bombs. The enriched uranium was used in the Little Boy atomic bomb Used in the atomic bombing of Hiroshima. Production of enriched uranium ended in 1964, and gaseously diffusion finally ceased on the site on 27 August 1985. Demolition of all five gaseous diffusion plants was completed in February 2017.

About K-25 in brief

K-25 was the codename given by the Manhattan Project to the program to produce enriched uranium for atomic bombs. When it was built in 1944, the four-story K-25 gaseous diffusion plant was the world’s largest building, comprising over 1,640,000 square feet of floor space and a volume of 97,500,000 cubic feet. The enriched uranium was used in the Little Boy atomic bomb Used in the atomic bombing of Hiroshima. Production of enriched uranium ended in 1964, and gaseously diffusion finally ceased on the site on 27 August 1985. The Oak Ridge Gaseous Diffusion Plant was renamed the Oak Ridge K- 25 Site in 1989, and the East Tennessee Technology Park in 1996. Demolition of all five gaseOUS diffusion plants was completed in February 2017. The discovery of the neutron by James Chadwick in 1932, followed by that of nuclear fission in uranium by the German chemists Otto Hahn and Fritz Strassmann in 1938, opened up the possibility of a controlled nuclear chain reaction with uranium. The former makes up just 0. 714 percent of the uranium atoms in natural uranium, about one in every 140; natural uranium is 99. 28 percent uranium-238. There is also a tiny amount of uranium-234, which accounts for 0. 006 percent, which makes up about 1 in every 2,000 atoms of uranium. In 1940, British physicist Mark Oliphant assigned two refugee physicists, Otto Frisch and Rudolf Peier, the task of investigating the feasibility of an atomic bomb, ironically because their status as enemy aliens precluded their working on secret projects like radar.

Their work was published in March 1940 in the book, “The Secret War: The Story of the Atomic Bomb” (Piatkus & Co., Ltd., London). The book was published by Piatkus and Co., London, and is available in hard copies for about $1,000 (US) or $2,000 ($3,000) in hard copy. The Kindle version of the book is available for $1.99 (U.S.) or $3.49 (UK) with the Kindle version for $2.99 ($3.99) in the Kindle edition is $4.99 (£2,99).
