The Nevada National Security Sites (N2S2 [1] or NNSS), popularized as the Nevada Test Site (NTS) until 2010, [2] is a reservation of the United States Department of Energy located in the southeastern portion of Nye County, Nevada, about 65 mi (105 km) northwest of the city of Las Vegas.
The first use of "levitated" cores made of oralloy. Tested components for Mark 4 design. Ranger: 1951 5: 5: 5: 1 to 22 40: First tests at the Nevada Test Site. Operation originally named "Operation Faust". Greenhouse: 1951 4: 4: 4: 46 to 225 398: George shot was physics experiment relating to the hydrogen bomb; Item shot was first boosted ...
The Operation Ivy test series was the first to involve a hydrogen bomb rather than an atomic bomb, further to the order of President Harry S. Truman made on January 31, 1950, that the US should continue research into all forms of nuclear weapons.
Edward Teller, perhaps the most ardent supporter of the development of the hydrogen bomb, was in Berkeley, California, at the time of the shot. [32] He was able to receive first notice that the test was successful by observing a seismometer, which picked up the shock wave that traveled through the earth from the Pacific Proving Grounds.
Castle Bravo shot of 1 March 1954, was the first test of a deployable (solid fuel) thermonuclear weapon, and also (accidentally) the largest weapon ever tested by the United States (15 megatons). It was also the single largest U.S. radiological accident in connection with nuclear testing.
Test No. 6, First hydrogen bomb test – June 17, 1967; CHIC-16, 200 kt-1 Mt atmospheric test – June 17, 1974 [25] #21, Largest hydrogen bomb tested by China (4 megatons) - November 17, 1976 #29, Last atmospheric test – October 16, 1980. This is to date the last atmospheric nuclear test by any country. [26]
The Ivy Mike test was the world's first "hydrogen bomb", producing a full-scale thermonuclear or fusion explosion. The Ivy Mike device used liquid deuterium , an isotope of hydrogen , making it a "wet" bomb.
Ivy Mike, the first full test of the Teller–Ulam design (a staged fusion bomb), with a yield of 10.4 megatons (November 1, 1952). The Teller–Ulam design is a technical concept behind modern thermonuclear weapons, also known as hydrogen bombs.
