Wellerstein's creation has garnered some popularity amongst nuclear strategists as an open source tool for calculating the costs of nuclear exchanges. [11] As of October 2024, more than 350.7 million nukes have been "dropped" on the site. [citation needed] The Nukemap was a finalist for the National Science Foundation's Visualization Challenge ...
The first nuclear explosive devices provided the basic building blocks of future weapons. Pictured is the Gadget device being prepared for the Trinity nuclear test.. Nuclear weapons design are physical, chemical, and engineering arrangements that cause the physics package [1] of a nuclear weapon to detonate.
Sub-MeV radiation from a nuclear explosion may be more important in (empty) space. Given this realization, during the 1960s [3] the U.S. military began to investigate whether military systems could be tested for their response to nuclear-weapon generated pulsed x-rays with flash x-ray machines. At the time these were fairly small, primarily ...
The aim of the project was to build the first nuclear bomb, and these lectures were a very concise introduction into the principles of nuclear weapon design. Serber was a postdoctoral student of J. Robert Oppenheimer , the leader of the Los Alamos Laboratory, and worked with him on the project from the very start.
In an implosion-type nuclear weapon, polygonal lenses are arranged around the spherical core of the bomb. Thirty-two "points" are shown. Other designs use as many as 96 or as few as two such points. An explosive lens—as used, for example, in nuclear weapons—is a highly specialized shaped charge.
The Cold War ended in 1991, but the looming threat of nuclear attack lives on with more than 14,900 nuclear weapons wielded by nine nations.. A terrorist-caused nuclear detonation is one of 15 ...
A nuclear weapon [a] is an explosive device that derives its destructive force from nuclear reactions, either fission (fission or atomic bomb) or a combination of fission and fusion reactions (thermonuclear bomb), producing a nuclear explosion. Both bomb types release large quantities of energy from relatively small amounts of matter.
This design changed the physics behaviour of the weapon and a new nuclear test was required to certify the new design. [10] In early 1988, a new 3-dimensional computer simulation suggested that the weapon was not one-point safe under certain conditions. Nuclear testing carried out in December 1988 and February 1989 confirmed these findings. [11]
