MOSCOW, April 14 (UPI) -- It seems Iranian President Mahmoud Ahmadinejad simply cannot help but shock the world with his revelations about the sensational achievements of Iranian nuclear physicists.

In February 2006 he announced they coped with thermonuclear reactions. This time he spoke about the most advanced Iranian technologies of the budding Iranian nuclear-enrichment industry. He was referring to the grandiose commissioning of 6,000 IR-2 centrifuges -- Iranian classification -- at the Natanz nuclear facility in Isfahan on the Day of Nuclear Technology.

But how new are these "most advanced technologies"?

The commissioning of IR-2 centrifuges was not a surprise for experts. In the middle of last February Iran gave the International Atomic Energy Agency all the required information about them. Indicatively, a week before the Western media wrote that Iran had decided to install next-generation P-2 centrifuges -- IR-2 in Iranian classification -- at Natanz.

Experts maintain that P-2 centrifuges -- the prototype of the IR-2 -- were used by Pakistan -- hence, the abbreviation P -- and are a copy of a model of German centrifuges from the early 1970s. Its design was stolen from the URENCO international concern by a Pakistani nuclear physicist that became famous after giving it to Iran. His name is A.Q. Khan.
