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 ...
Test with "energy budget". Competition between UCRL and LASL over budget allocation was high. Project 57: 1957 1: 1: 1: 0 0: The first safety test, asking whether an improperly ignited bomb (as in a plane crash) would cause a nuclear blast. Plumbbob: 1957 29: 29: 25: 0 to 74 345: Included the largest atmospheric test in CONUS. Project 58+58A ...
The People's Republic of China conducted 45 tests (23 atmospheric and 22 underground, all conducted at Lop Nur Nuclear Weapons Test Base, in Malan, Xinjiang) 596 First test – October 16, 1964; Film is now available of 1966 tests here at time 09:00 [24] and another test later in this film. Test No. 6, First hydrogen bomb test – June 17, 1967
Nuclear test sites are nuclear weapons testing locations in the world where nuclear weapons have either been detonated or specialist preparations made for nuclear weapons to be detonated. Subcategories

The site was the primary testing location of American nuclear devices from 1951 to 1992; 928 announced nuclear tests occurred there. Of those, 828 were underground [ 9 ] (62 of the underground tests included multiple, simultaneous nuclear detonations, adding 93 detonations and bringing the total number of NTS nuclear detonations to 1,021, of ...
Nuclear weapons testing did not produce scenarios like nuclear winter as a result of a scenario of a concentrated number of nuclear explosions in a nuclear holocaust, but the thousands of tests, hundreds being atmospheric, did nevertheless produce a global fallout that peaked in 1963 (the bomb pulse), reaching levels of about 0.15 mSv per year ...
The first use of the Pacific Proving Grounds was during Operation Crossroads, the first nuclear testing done after the atomic bombing of Hiroshima and Nagasaki. Two fission bombs, both with a yield of 21 kilotons, were tested at Bikini Atoll. "Able" was detonated at an altitude of 520 ft (158 m) on July 1, 1946, and "Baker" was detonated at a ...
