Gas centrifuge

A gas centrifuge is a device that performs isotope separation of gases. A centrifuge relies on the principles of centrifugal force accelerating molecules so that particles of different masses are physically separated in a gradient along the radius of a rotating container. A prominent use of gas centrifuges is for the separation of uranium-235 (²³⁵U) from uranium-238 (²³⁸U). The gas centrifuge was developed to replace the gaseous diffusion method of ²³⁵U extraction. High degrees of separation of these isotopes relies on using many individual centrifuges arranged in series that achieve successively higher concentrations. This process yields higher concentrations of ²³⁵U while using significantly less energy compared to the gaseous diffusion process.
