Process to separate isotopes in which heavy atoms are split from the lighter atoms by centrifugal forces. The separation factor depends on the mass difference of the isotopes to be separated. The process is suitable for the separation of uranium isotopes, the achievable separation factor amounts to 1.25. Uranium enrichment plants applying this process are operated in Gronau/Wesphalia (Germany) and by URENCO at Capenhurst (UK).
