Talk:Zippe-type centrifuge

message: What is the difference between the Zippe type and other gas centrifuges?  (Maybe this article needs to be merged into the gas centrifuge article?)  Lchiarav 06:30, 28 November 2005 (UTC)
replies: text: My recollection from the sources is that magnetic bearings and use of a vacuum were his major innovations, together with fine engineering.  This extlink tells more. I'm not pro-merger, but there could be more clarification.  I do wonder if Gas centrifuge should be more generic, rather than just about uranium isotope separation. - Rwendland 10:48, 29 November 2005 (UTC)

thread_title:  What is the actual cost of a centrifuge? 

message: The article states: The AC motors which drive the centrifuge require higher than normal frequency AC, and the several hundred Hertz AC is detectable by other countries SIGINT ELINT.
This sounds wrong. "Several hundred Hz" is not a very high frequency, particularly for a centrifuge that itself spins in the kilohertz range. If "several hundred thousand Hz" is meant, it is easier to believe that it will radiate detectably, but still difficult to see how such an emission could be identified as a centrifuge in operation with any certainty (for example, the horizontal sync of high-end computer monitors will have their low harmonics in this range). Anybody know what is actually intended to be said here? Henning Makholm 22:21, 12 December 2006 (UTC)

message: Ref #2 was linked to a BLOG. This is not good. Blogs are not reliable sources. The blog itself referred to a Washington Post article so I wonder why that was not used as the reference? The reference also had no date, source or title(like 1. below), Very Un-encyclopaedic! I have linked to the Washington Post article, which does not mention the bit about fingerprints being enough to unbalance the cetrifuge, though it is possible.

thread_title:  Poor Reference 

message: Does anybody know how the centrifuge is sealed at the top to prevent UF6 from escaping into the vacuum outside the rotor?. I'd imagine at 90000 RPM friction would be a no-no , so how is it done? Does it simply rely on the high RPM generating a low pressure near the axis and then pump out any UF6 that escapes, or is there some more ingenious design? 95.109.104.4 (talk) 18:49, 25 October 2010 (UTC)

thread_title:  External links modified 

message: "After the scientists were released from Soviet captivity in 1956..." The article makes no previous mention of scientists. Who were they? Why were they in captivity? What were the circumstances of their release? 79.73.150.27 (talk) 02:28, 11 August 2016 (UTC)
thread_title:  Scientists? What scientists? 

message: The UF6 hits the scoops collecting the enriched and depleted fractions at much above sonic speed. Supersonic shock waves, propagating in the gas, would propbably destroy any separation. The scoop for the heavier fraction is behind a perforated baffle, which probably prevents propagation of the shock waves. But the other scoop is everywhere drawn without baffle; it is intended to slow down gas rotation locally, hence reduce the radial pressure gradient and thus induce the countercurrent. Does anybody know, how shock waves are avoided there? Maybe they use a modified (perhaps only short) baffle? Dolorpiedo (talk) 10:12, 22 January 2023 (UTC)
