Iran's President Mahmoud Ahmadinejad is offering to resume talks over its nuclear program as soon as possible, according to a copy of a letter he sent to the European Union and obtained by CNN.
Iran flaunted a new generation of centrifuges and mastery of the nuclear fuel cycle on Wednesday as Ahmadinejad, clad in a white lab coat, was on hand to load domestically made fuel rods into the core of a Tehran reactor.
Also announced was an intent to start production of yellowcake, a chemically treated form of uranium ore used for making enriched uranium.
United Nations sanctions ban Iran from importing yellowcake. Domestic production would further Iran's nuclear self-sufficiency.
In a speech outlining the latest developments, Ahmadinejad said Iran was willing to share its nuclear knowledge with other nations that subscribe to the watchdog International Atomic Energy Agency (IAEA).
