Iran is engaged in transferring new generations of advanced centrifuges used to enrich uranium from a warehouse to the main production center at Natanz, according to a classified document compiled by the International Atomic Energy Agency (IAEA) that was obtained by the Bloomberg website.
The document shows that Iranian engineers recently installed special pipes in the reactor that are reinforced in order to withstand the high pressure of uranium production created when using advanced centrifuges.
This transfer of the centrifuges takes place about a month after the explosion at the Natanz reactor, which is estimated to have caused a delay of one to two years to the Iranian nuclear program.
