The demon core was a sphere of plutonium that was involved in two fatal radiation accidents when scientists tested it as a fissile core of an early atomic bomb. It was manufactured in 1945 by the Manhattan Project, the U.S. nuclear weapon development effort during World War II.
The project was a key part of the Manhattan Project, the United States nuclear weapons development program during World War II. Its purpose was to convert natural (not isotopically enriched) uranium metal into plutonium-239 by neutron activation , as plutonium is simpler to chemically separate from spent fuel assemblies, for use in nuclear ...
The world’s first full-scale nuclear reactor was part of the Manhattan Project. ... The design allowed the reactor to produce plutonium-239 by irradiating naturally occurring uranium with neutrons.
Russell worked on the Manhattan Project from 1942 to 1946 at the University of Chicago's Met Lab, researching the isolation and extraction of plutonium-239 from uranium. [3] In 1947 to 1953, Edwin served as chairman of the Division of Science at Allen University in Columbia, SC.
Within the Manhattan Project, plutonium was referred to often by its code designation "49" (from its atomic number 94 and its atomic mass 239) or simply the "product". Few outside of the Manhattan Project would have known of plutonium, much less of the dangers of radioactive isotopes inside the body.
A theoretical 100% pure 239 Pu weapon could also be constructed as a gun-type weapon, like the Manhattan Project's proposed Thin Man design. In reality, this is impractical because even "weapons grade" 239 Pu is contaminated with a small amount of 240 Pu, which has a strong propensity toward spontaneous fission.
