Nuclear weapons tests are experiments carried out to determine the performance, yield, and effects of nuclear weapons. Testing nuclear weapons offers practical information about how the weapons function, how detonations are affected by different conditions, and how personnel, structures, and equipment are affected when subjected to nuclear ...
During the 1958 moratorium on nuclear testing, a number of sub-critical tests were performed underground to learn more about the dynamics of explosions and the metallurgy of plutonium. The US's first nuclear weapons lab, founded in the Manhattan Project in high secrecy. Tech Area 49 is an open area south of the lab, where zero-yield tests were ...
In the five decades between 1945 and the 1996 Comprehensive Nuclear Test-Ban Treaty (CTBT), over 2,000 nuclear tests were carried out, 1,032 of them by the United States and 715 of them by the ...
After the 1989 end of the Cold War and the 1991 dissolution of the Soviet Union, the U.S. nuclear program was heavily curtailed; halting its program of nuclear testing, ceasing its production of new nuclear weapons, and reducing its stockpile by half by the mid-1990s under President Bill Clinton. Many former nuclear facilities were closed, and ...
Afterwards, the Comprehensive Test Ban Treaty was signed and ratified by the major nuclear weapons powers, and the number of worldwide nuclear tests decreased rapidly. [24] India and Pakistan conducted nuclear tests in 1998, but afterwards only North Korea conducted nuclear tests--in 2006, 2009, 2013, twice in 2016, and in 2017. [24] [25]
The nuclear weapons tests of the Soviet Union were performed between 1949 and 1990 as part of the nuclear arms race. The Soviet Union conducted 715 nuclear tests using 969 total devices by official count, including 219 atmospheric, underwater, and space tests and 124 peaceful use tests . [ 1 ]
