TEHRAN, Iran – Iran confirmed for the first time Monday that it converted 37 tons of raw uranium into gas, a key step ahead of enrichment, before it suspended all such activities in November under international pressure.
The confirmation means Tehran is in a position to quickly start enriching uranium if it chose to end its suspension of enrichment-related acitivies. It comes at a crucial time, with Europe trying in fragile negotiations to seal an agreement to ensure Iran's nuclear program does not produce nuclear weapons.
The Europeans agreed last year that Iran could finish converting the 37 tons. Iran had begun processing the material, mined from its own uranium resources, in a rushed attempt to do it just before the suspension.
If processed further into UF-6, the material could be fed into centrifuges and enriched, allowing it to be used either to produce electricity or make nuclear weapons.
"We converted all the 37 tons of uranium concentrate known as yellowcake (search) into UF-4 at the Isfahan Uranium Conversion Facility before we suspended work there," Saeedi said.
Nuclear experts say that when fully processed, the 37 tons of yellowcake can theoretically yield more than 200 pounds of weapons-grade uranium, enough to make five crude nuclear weapons.
Iran agreed to suspend actual enrichment at its Natanz (search) uranium enrichment plant in 2003 to avoid U.N. Security Council referral for possible sanctions.
To bolster international confidence, Tehran in late 2004 suspended other uranium enrichment-related activities — including the conversion of yellowcake into gas and the building of centrifuges.
Natanz and the uranium conversion facility in Isfahan house the heart of Iran's nuclear program. The Isfahan conversion facility reprocesses uranium ore concentrate into gas, which is taken to Natanz and fed into centrifuges for enrichment.
To show its dissatisfaction with lack of progress in nuclear talks between Iran and the key European powers, Foreign Ministry spokesman Hamid Reza Asefi said Sunday Iran has decided to resume some uranium reprocessing activities.
Saeedi said that may happen in the next two or three days.
France, Britain and Germany, acting on behalf of the 25-nation European Union, are offering Iran economic incentives in return for guarantees that Tehran will not use its nuclear program to make weapons. Last month's Iranian-European talks yielded no results.
