У нас секретно, как всегда. А то что лучше и ежу понятно. Вот кусочек из вики: Suggested in 1919, the centrifugal process was first successfully performed in 1934. Jesse Beams and coworkers at the University of Virginia developed the process by separating two chlorine isotopes through a vacuum ultracentrifuge. It was one of the initial isotopic separation means pursued during the Manhattan Project, but research was discontinued in 1944 as it was felt that the method would not produce results by the end of the war, and that other means of uranium enrichment (gaseous diffusion and electromagnetic separation) had a better chance of success in the short term. However this method was successfully used in the Soviet nuclear program, making the Soviet Union the most effective supplier of enriched uranium. --------------- А эти центрифуги из Пайктона, и да, это древние (1984 год) прототипы. Завод в Пайктоне обещают в 14-м году. Пока там экспериментальное производство.
