Universal History Annotation << Back Scientific Expedition to New Earth. First Underwater Explosion in Ussr N.M. Kuznetsov Institute of Chemical Physics of the USSR, Founder and director was Academician (Nobel Prize 1956) Nikolai Semyonov, belongs to a large contribution to the organization building the nuclear test site near Semipalatinsk, in carrying out nuclear explosions in three areas - on the ground, in the atmosphere and underground and multilateral experimental and theoretical study of the effects of atomic weapons. Multilateral experimental and theoretical study of the effects of atomic weapons. Memories of the many participants - managers and executives work published in two volumes... There is also a material air explosion of a hydrogen on the Super Novaya Zemlya autumn 1963 but the first underwater test of an atomic weapon in the USSR there was nothing. It seems that this gap is not filled by anywhere in accessible form. Now no one is left out of the administrative board of scientists ICP,. who participated in the expedition to Novaya Zemlya in 1955. Yes, and now working at the ICP and the former Special Sector ICP – in IDGAN (Institute of Geosphere Dynamics AN) of the participants in this expedition except me only three doctors of sciences G.I. Jumps (ICP), V.N. Kostyuchenko B.D. Khristophorov (IDGAN). As member of the expedition and witness first underwater nuclear explosion, I decided to write about it in these memoirs. Some of the «lyrical» retreat, hopefully not too violate the integrity of the story (and maybe make it less boring). Keywords: Expedition, nuclear explosion, superbomb, underwater nuclear explosion.
