The Soviet Union's 1983 nuclear test series was a group of 27 nuclear tests conducted in 1983.
 These tests followed the "1982 Soviet nuclear tests" series and preceded the "1984 Soviet nuclear tests" series.
The Soviet Union's 1987 nuclear test series was a group of 24 nuclear tests conducted in 1987.
 These tests followed the "1985 Soviet nuclear tests" series and preceded the "1988 Soviet nuclear tests" series.
The Soviet Union's 1988 nuclear test series was a group of 16 nuclear tests conducted in 1988.
 These tests followed the "1987 Soviet nuclear tests" series and preceded the "1989 Soviet nuclear tests" series.
Yuri Fyodorovich Orlov (Russian: Ю́рий Фёдорович Орло́в , born 13 August 1924 in Moscow) is Professor of Physics and Government at Cornell University, a former Soviet dissident, Soviet nuclear physicist and human rights activist, a founder of the Moscow Helsinki Group and Soviet Amnesty International group.
 He was declared a prisoner of conscience when served nine years in prison and internal exile for monitoring the Helsinki human rights accords as a founder of human rights movement in the Soviet Union.
The Soviet Union's 1984 nuclear test series was a group of 29 nuclear tests conducted in 1984.
 These tests followed the "1983 Soviet nuclear tests" series and preceded the "1985 Soviet nuclear tests" series.
The SS "Fizik Kurchatov" (Russian: "Физик Курчатов" ) was a multi-purpose tweendecker freighter owned by the Soviet Black Sea Shipping Company.
 A Leninsky Komsomol-class cargo ship, it had steam turbine engines.
 The ship was named after Soviet physicist Igor Kurchatov (1903–1960).
Kurchatov (in Kazakh and Russian: Курча́тов) is a town in East Kazakhstan Region in north-east Kazakhstan.
 Named after Soviet nuclear physicist Igor Kurchatov, the town was once the centre of operations for the adjoining Semipalatinsk Test Site.
 With the cessation of nuclear testing and the decommissioning of the test site, Kurchatov's population has fallen from over 20,000 to around 8,000.
 In its heyday Kurchatov (which was known by its postal code Semipalatinsk-21) was a closed city, one of the most secretive and restricted places in the Soviet Union.
 The nuclear facilities at Kurchatov are managed by the Kazakhstan Institute of Atomic Energy, a division of the country's National Nuclear Center.

Igor Vasilyevich Kurchatov (Russian: И́горь Васи́льевич Курча́тов ; 8(21) January 1903 – 7 February 1960), was a Soviet nuclear physicist who is widely known as the director of the Soviet atomic bomb project.
 Along with Georgy Flyorov and Andrei Sakharov, Kurchatov is widely remembered and dubbed as the "father of the Soviet atomic bomb" and later, "the father of the Soviet Nuclear Missile" for his directorial role in the development of the Soviet nuclear program, in a clandestine program during World War II formed in the wake of the USSR's discovery of the Western Allied efforts to develop nuclear weapons.
 After nine years of covert development, the Soviet Union successfully tested its first nuclear weapon, codenamed "First Lightning" at the Semipalatinsk Test Range in 1949.
 In 1954 he was awarded the USSR State Prize in physics.
The Soviet Union's 1989 nuclear test series was a group of 7 nuclear tests conducted in 1989.
 These tests followed the "1988 Soviet nuclear tests" series and preceded the "1990 Soviet nuclear tests" series.
The Soviet Union's 1985 nuclear test series was a group of 10 nuclear tests conducted in 1985.
 These tests followed the "1984 Soviet nuclear tests" series and preceded the "1987 Soviet nuclear tests" series.
