A re-creation of the experiment involved in the 1945 incident. The sphere of plutonium is surrounded by tungsten carbide blocks acting as neutron reflectors.. 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.
Trinity was the code name of the first detonation of a nuclear weapon, conducted by the United States Army at 5:29 a.m. MWT [a] (11:29:21 GMT) on July 16, 1945, as part of the Manhattan Project. The test was of an implosion-design plutonium bomb, nicknamed " The Gadget ", of the same design as the Fat Man bomb later detonated over Nagasaki ...
For nuclear weapon tests, a salvo is defined as two or more underground nuclear explosions conducted at a test site within an area delineated by a circle having a diameter of two kilometers and conducted within a total period of time of 0.1 second. [2] The two nuclear bombs dropped in combat over Japan in 1945.
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. There are three existing basic design ...
Nuclear weapons safety experiments were conducted to study the possibility of a nuclear weapon detonation during an accident. On July 26, 1957, a safety experiment, Pascal-A , was detonated in an unstemmed hole at the Nevada Test Site, becoming the first underground shaft nuclear test.
Chicago Pile-1 (CP-1) was the world's first artificial nuclear reactor.On 2 December 1942, the first human-made self-sustaining nuclear chain reaction was initiated in CP-1 during an experiment led by Enrico Fermi.
Ivy Mike was the codename given to the first full-scale [note 1] test of a thermonuclear device, in which a significant fraction of the explosive yield comes from nuclear fusion.
