What is the name given to the final series of 7 US nuclear tests that took place in 1991 to 1992?
Operation Julin The United States's Julin nuclear test series was a group of 7 nuclear tests conducted in 1991–1992. These tests followed the "Operation Sculpin" series, and were the last before negotiations began for the Comprehensive Test Ban Treaty.
Nuclear weapon A nuclear weapon is an explosive device that derives its destructive force from nuclear reactions, either fission (fission bomb) or from a combination of fission and fusion reactions (thermonuclear bomb). Both bomb types release large quantities of energy from relatively small amounts of matter. The first test of a fission ("atomic") bomb released an amount of energy approximately equal to 20,000 tonTNT . The first thermonuclear ("hydrogen") bomb test released energy approximately equal to 10 e6tonTNT . A thermonuclear weapon weighing little more than 2400 lb can release energy equal to more than 1.2 e6tonTNT . A nuclear device no larger than traditional bombs can devastate an entire city by blast, fire, and radiation. Since they are weapons of mass destruction, the proliferation of nuclear weapons is a focus of international relations policy.
