The problem of separation of isotopes in a concurrent gas centrifuge is solved analytically for an arbitrary binary mixture of isotopes. The separative power of the optimised concurrent gas centrifuges for the uranium isotopes equals to dU ¼ (V/700 m/s)2 (300 K/T)(L/1 m) kg$SWU/yr, where L and V are the length and linear velocity of the rotor of the gas centrifuge and T is the temperature. This equation agrees well with the empirically determined separative power of optimised counter-current gas centrifuges. | Nuclear Engineering and Technology 48 2016 7 19-7 26 Available online at ScienceDirect Nuclear Engineering and Technology journal homepage locate net Original Article Separative Power of an Optimised Concurrent Gas Centrifuge CrossMark Sergey Bogovalov and Vladimir Borman National Research Nuclear University MEPHI Kashirskoje shosse 31 Moscow 115409 Russia ARTICLE INFO ABSTRACT Article history The problem of separation of isotopes in a concurrent gas centrifuge is solved analytically for Received 25 July 2015 Received in revised form 26 November 2015 Accepted 6 January 2016 Available online 6 April 2016 an arbitrary binary mixture of isotopes.

Introduction Separation of heavy isotopes in gas centrifuges hereafter GCs has been used for industrial production of enriched uranium from the middle of the past century. It is likely that this method of isotope separation will remain the most efficient from the economical point of view for the next few decades. Despite the long history of using this method a lot of important problems of the physics of the isotope separation remain unsolved. The problem of the separative power of GCs is the most important among them. Knowledge or estimation of the separative power of GCs is necessary for design of efficient GCs and important for experts dealing with .
