The Menezh exhibition center in Russia’s capital city Moscow is getting ready to exhibit a replica of the Soviet "Tsar Bomba" that was exploded in the Arctic in 1961 and is known as the most powerful nuclear device ever detonated.
The exhibition, named "70 years of the atomic industry - a chain reaction of success," will take place in Moscow next month and is devoted to Russia's atomic accomplishments since 1945.
The exhibit's main attraction will be AN-602 hydrogen bomb casings which will be delivered to Moscow from Sarov - a closed nuclear research town 465 kilometers east of the capital.
The exhibition at the Manezh center will also feature personal testimonies from famous Soviet nuclear scientists, secret documents from Soviet archives not previously released, models of nuclear reactors, and a nuclear-powered icebreaker.
The Soviet Union set off the 58-megaton Tsar Bomba on northern Russian island of Severny. The bomb was about 3,000 times more powerful than the Hiroshima atom bomb and needed a custom made bomber to be dropped.
The bomber's altitude fell by nearly one kilometer due to the blast from the bomb and the shockwave from the explosion is said to have orbited the Earth three times.
The bomb was nicknamed "Kuzma's Mother," from a Russian phrase meaning "we'll teach you a lesson."
The idiom was used by Soviet leader Nikita Khrushchev against former US Vice-President Richard Nixon in 1959, during the Cold War nuclear arms race, Russian media has reported.
