Ivy King Detonation 1952
Ivy King
https://en.wikipedia.org/wiki/Ivy_King
Ivy King was the largest pure-fission nuclear bomb ever tested by the United States.
The production of Ivy King was hurried to be ready in case its sister project, Ivy Mike, failed in its attempt to achieve a thermonuclear reaction. The Ivy King test actually took place two weeks after Mike. Unlike the Mike bomb, the Ivy King device could theoretically have been added to United States' nuclear arsenal because it was designed to be air-deliverable.
On November 16, 1952 at 11:30 local time (23:30 GMT) a B-36H bomber dropped the bomb over a point 2,000 feet (610 m) north of Runit Island in the Enewetak atoll, resulting in a 500 kiloton explosion at 1,480 feet (450 m). The tropopause height at the time of the detonation was about 58,000 feet (18 km). The top of the King cloud reached about 74,000 feet (23 km) with the mushroom base at about 40,000 feet (12 km).[2]
The Ivy King bomb, designated as a Mk-18 bomb and named the "Super Oralloy Bomb", was a modified version of the Mk-6D bomb. Instead of using an implosion system similar to the Mk-6D, it used a 92-point implosion system initially developed for the Mk-13. Its uranium-plutonium core was replaced by 60 kg of highly enriched uranium (HEU) fashioned into a thin-walled sphere equivalent to approximately four critical masses. The thin-walled sphere was a commonly used design, which ensured that the fissile material remained sub-critical until imploded. The HEU sphere was then enclosed in a natural-uranium neutron reflector. To physically prevent the HEU sphere collapsing into a critical condition if the surrounding explosives were detonated accidentally, or if the sphere was crushed following an aircraft accident, the hollow center was filled with a chain made from aluminum and boron, which was pulled out to arm the bomb. The boron-coated chain also absorbed the neutrons needed to drive the nuclear reaction.
The primary designer of the Super Oralloy Bomb, physicist Ted Taylor.
Ted Taylor (physicist)
https://en.wikipedia.org/wiki/Ted_Taylor_(physicist)
Theodore Brewster Taylor was an American theoretical physicist, specifically concerning nuclear energy. His higher education includes a PhD from Cornell University in theoretical physics. Although Taylor is relatively unknown to the public, his most noteworthy contributions to the field of nuclear weaponry were his small bomb developments at the Los Alamos Laboratory in New Mexico. He is credited with numerous landmarks in fission nuclear weaponry development, including having developed the smallest, most powerful, and most efficient fission weapons ever tested by the US. Though Taylor was not considered a brilliant physicist from a calculative viewpoint, his vision and creativity allowed him to thrive in the field. The later part of Taylor's career was focused on nuclear energy instead of weaponry, and included his work on Project Orion, nuclear reactor developments, and anti-nuclear proliferation.
