The authors were associated with the Russian Research Center, "Kurchatov Institute", Moscow and Experimental Machine Building Design Bureau, Nizhny Novgorod. The Kurchatov Institute (since 2010) i.e. National Research Centre "Kurchatov Institute"; 1991-2010 is Russia's leading research and development institution in the field of nuclear energy. It was known as I. V. Kurchatov Institute of Atomic Energy. The Kurchatov Institute is located at 1 Kurchatov Square, Moscow. It is named after Igor Kurchatov. Until 1955 known under a secret name "Laboratory No. 2 of the USSR Academy of Sciences", the Kurchatov Institute was founded in 1943 with the initial purpose of developing nuclear weapons. The majority of Soviet nuclear reactors were designed in the Institute, including the on-site F-1, which was the first nuclear reactor outside North America to sustain criticality. The additional listed main authors are: From the Kurchatov are N. E. Kukharkin, I. S. Mosevitsky, E. S. Glushkno, V. N. Grebennik, Yu. G. Degaltsev, V. E. Demin, L. L. Lyshov, A. G. Morozov, A. A. Khrulev, D. F. Tsurikov, A. S. Chernikov, and V. M. Makarov and from the Experimental Machine Building are: I. N. Gorelov, V. I. Evseev, Yu. P. Sukharev, N. G. Kodachigov, and A. A. Kudryashov. Weapons-grade nuclear material is any fissionable nuclear material that is pure enough to be used to make a nuclear weapon or has properties that make it particularly suitable for nuclear weapons use. Plutonium and uranium in grades normally used in nuclear weapons are the most common examples. Only fissile isotopes of certain elements have the potential for use in nuclear weapons. For such use, the concentration of fissile isotopes uranium-235 and plutonium-239 in the element used must be sufficiently high. Uranium from natural sources is enriched by isotope separation, and plutonium is produced in a suitable nuclear reactor. Presumed First Edition, First printing in English.
