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 ]
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 Obninsk Nuclear Power Plant in 2008. The first nuclear power plant constructed in the world was the Obninsk Nuclear Power Plant, built near Moscow on June 26, 1954. It was intended as an experiment to determine the capabilities of nuclear power in supplying a commercial grid. At the beginning of its operation, it produced 5 MWe. [2]
The standard official list of tests for American devices is arguably the United States Department of Energy DoE-209 document. [5] The United States conducted around 1,054 nuclear tests (by official count) between 1945 and 1992, including 216 atmospheric, underwater, and space tests. [9] Some significant tests conducted by the United States include:
1975 Soviet nuclear tests; 1976 Soviet nuclear tests; 1977 Soviet nuclear tests; 1978 Soviet nuclear tests; 1979 Soviet nuclear tests; 1980 Soviet nuclear tests; 1981 Soviet nuclear tests; 1982 Soviet nuclear tests; 1983 Soviet nuclear tests; 1984 Soviet nuclear tests; 1985 Soviet nuclear tests; 1987 Soviet nuclear tests; 1988 Soviet nuclear ...
The EMP from the same test caused the destruction of the Karaganda power plant, and shut down 1,000 km (620 mi) of shallow-buried power cables between Astana (then called Aqmola) and Almaty (then called Alma-Ata). [3] The Partial Test Ban Treaty was passed the following year, ending atmospheric and exoatmospheric nuclear tests.
Most of the nuclear tests taking place at various sites further to the west and the south, some as far as into Karagandy Region. The Soviet Union conducted 456 nuclear tests at Semipalatinsk from 1949 until 1989 with little regard for their effect on the local people or environment. The full impact of radiation exposure was hidden for many ...
Many incidents occurred at various power plants operating the RBMK reactor. Most of them were covered up by the USSR government. [citation needed] These are some of the known incidents at the RBMK reactors: Explosion of a tank holding radioactive gases at the Leningrad Nuclear Power Plant unit 1 in January 1975
