Talk:Gas centrifuge

message: Just a note to people who maintain these pages.. CNN was recently referencing the P1 and P2 centrifuges, and searching for "P1 Centrifuge" or "P2 Centrifuge" does not lead you here, which is the only place I found any information on what it was they were talking about.
:Thanks for the input. I've created "redirect" pages from those names to here, to help future readers find this article. Cheers, -Will Beback 21:49, 25 April 2006 (UTC)

message: but this http://www.nytimes.com/2012/05/28/world/middleeast/iran-wont-halt-production-of-higher-grade-uranium.html was my source for changing the number of Iranian centrifuges to 9,000.  Is this information even relevant?
Also, a wealth of information to be added right here:  http://www.world-nuclear.org/info/inf28.html.  — Preceding unsigned comment added by 130.20.161.139 (talk) 03:22, 27 July 2012 (UTC)
thread_title: Not sure how to cite...

message: The picture and text do not make any sense.  The NRC URL says that heavier (that would be U-238, depleted) uranium is drawn to the wall of the centrifuge, and lighter stuff is in the middle.  The picture, on the other hand, indicates that heavier uranium is drawn to the bottom of the centrifuge, and lighter is drawn to the top (as does the text, which states that gravity achieves the separation.)  I think NRC URL text is correct, and think that the picture should be corrected.
in any event, the text at the bottom of the article says that heavier uranium is drawn from the top of the centrifuge, which is definitely wrong, and that lighter uranium is drawn from the bottom of the centrifuge, which also must be incorrect.  I've been wondering how this process works as Iran today stated it had put 1000 new centrifuges to work. SystemBuilder (talk) 19:26, 11 April 2008 (UTC)

message: In the first sentence, does "hyper-" in "hyper-centrifuge" actually have any meaning? Kaleja 21:10, 13 October 2006 (UTC)

thread_title:  Hyper? 

message: There is some interesting information on centrifuge types in an 15 years old Atomic Scientist article: 
The article mentions:
* Ultra-Centrifuge Nederland (UCN),
** CNOR machines, 2 separative work units
** SNOR, 5 separative work units
* Urenco consortium
** G-1 centrifuge, between 2 and 3 separative work units per year
** G-2, 5 to 6 separative work units
It is believed that most of Pakistan's centrifuges are based on the G-2 design.

thread_title:  Pakistan and Irak centrifuges 

message: The significant advantage of the gas centrifuge is that it relies on multiple centrifugal runs using cascades of centrifuges. This process yields higher concentrations of the uranium-235 isotopes with significantly less energy usage compared to the previous gaseous diffusion process.
This first statement is incorrect. Both of these processes rely on a cascade to yield higher concentrations of U235. The advantage of centrifuge is that the cost per SWU of the centrifuge in terms of electric power consumption is about 25 times less than the diffusion process.  —Preceding unsigned comment added by 160.84.254.241 (talk) 18:53, 18 June 2010 (UTC)
thread_title:  Advantage of the centrifuge over the gaseous diffusion process 

message: In the picture shown for a bank of gas centrifuges, the legend says that each centrifuge is 40 ft tall.  This number is probably wrong and a more accurate value should be closer to 4 ft or about 1 meter.  
I could not find any reference object in the picture to compare the length but the window (with drapes) is clearly seen and is very unlikely to be above 40 ft on the wall.  There are few references in the picture with which the scale can be inferred.
A 40 ft tall centrifuge will have tons of engineering problems.  Let us not bother about the details but unless a proper source is there for the length of the centrifuge, we should delete it.  It might have been just a typo.

replies: text: No, the American centrifuges shown there are really ~40 ft tall. They are truly huge:  . Not a typo... Google "American centrifuge Piketon" for more info. It's a design that the US explored in some detail in the 1980s for pilot plants. I don't know the details, only that it is much taller than the sorts of centrifuges which URENCO, Pakistan, etc., use. --Mr.98 (talk) 20:15, 25 December 2011 (UTC)
thread_title:  Wrong Picture... 

message: I know it's a fictitious force, but centripetal acceleration always acts radially inward, and it's the outward motion that centrifuges rely on, which is better explained on wikipedia's centrifugal force page.  — Preceding unsigned comment added by 173.25.54.191 (talk) 03:13, 6 October 2012 (UTC)
thread_title:  centrifugal is more accurate than centripetal 

message: The first paragraph of the Gas centrifugation process section contains the following sentence towards the end.  "The process began with the rotor is balanced in three stages." (sic)  This sentence is not grammatically correct.  The cited article indicates that balancing the rotors is a three stage operation, so it may make more sense to change this to something like "The rotors need to be properly balanced before operating the centrifuge; doing so is a three stage process."  38.99.56.154 (talk) 19:08, 27 January 2017 (UTC)
