Unformatted text preview: centrifuge machines as listed in the lecture notes, and comment on their availability. 5. Compute the alpha for a gas centrifuge enriching UF 6 at 300K spinning at a peripheral drum speed of 600 m/s (what is this in mph?) where the scoop extracts product at r/ a =0.85. 6. Solve for the minimum number of stages for a UF 6 enrichment plant with a top product of a. 3 w% U-235 b. 20 w% U-235 c. 90 w% U-235 for each separation technology (gaseous diffusion, centrifuge, Becker nozzle) if the feed is 0.711 w% U-235 and the tails are extracted at 0.3 w% U-235....
