Paul at Total Wonkerr adds some value to my post, including reminding readers of a late March story from AFP’s Michael Adler stating that a …
… diplomat said Iran had installed six cascades of 164 centrifuges each at Natanz and was test-running four of the cascades.
That would be 1,640 984 centrifuges.
I propose we follow Saeedi’s advice to “wait for the next 20 days when IAEA inspectors present their reports” to get the number, rather than inferring the worst from A-bomb’s bellicose rhetoric.
Update: My mistake, I too quickly read Adler to say that four more were under construction (rather than being test run). I suspect they have one or more cascades under construction beyond the six at the end of last month.
