This team acted as research supervisors of major engineering projects, which include : the startup of the first physical reactor, Ph ( 1946 ); the design, construction, and startup of plants for plutonium production, radiochemical extraction, and metallurgy ( Kurchatov, plants A, B, V, Chelyabinsk-40, in 1948 and 1949 ); the development of a physical reactor and an industrial heavy-water one ( Alikhanov, Laboratory no . 3, 1949; OK-180, Chelyabinsk-40, 1951 ); the development of a manufacturing technology of diffusion separation of uranium-235 and uranium-238 ( I . K . Kikoin, plant D-1, Sverdlovsk-65, 1949 1951 ); the development of industrial mass separators for the electromagnetic separation of isotopes of uranium ( L . A . Artsimovich, SU-20, Sverdlovsk-45, 1950 ); and, finally, the design calculation, modeling, construction, and production of the first atomic bomb ( Khariton, Arzamas-16, 1946 1949 ) ( Gaponov ).
