Iran Orders Boost in Uranium Enrichment Iran says it needs uranium enriched to 20 percent to fuel a medical research reactor Elizabeth Arrott | Cairo 08 February 2010 Iranian President Mahmoud Ahmadinejad, wears eye protection goggles as he visits an exhibition of Iran's laser science, in Tehran, Iran, 7 Feb 2010 Photo: ASSOCIATED PRESS Iranian President Mahmoud Ahmadinejad, wears eye protection goggles as he visits an exhibition of Iran's laser science, in Tehran, Iran, 7 Feb 2010 The head of Iran's atomic energy organization says he has ordered the further enrichment of uranium to start Tuesday. Iran's current processing program would likely need reconfiguring first, prompting speculation the announcement may have more to do with negotiations with the West than imminent enrichment. Iran's nuclear chief, Ali Akbar Salehi, said he would send a letter to the U.N. nuclear agency informing it of the decision to enrich uranium to 20 percent. Speaking to Iran's Arabic al-Alam television, Salehi said Iran would start the process in the presence of inspectors and observers from the International Atomic Energy Agency. The move follows an order Sunday by President Mahmoud Ahmedinejad to go ahead with further enrichment, one of the many varying responses Iranian officials have given to a U.N. plan to enrich the uranium abroad. The IAEA wants Iran to send most of its uranium stockpile to Russia and France to boost it to 20 percent and turn it into fuel rods. Such rods would be very difficult to enrich even more, for example to the 90 percent needed to make nuclear weapons. If Iran can manage to push the uranium to 20 percent on its own, and it is not clear that it can, Western scientists say it could also likely enrich it to weapons grade. Iran denies its nuclear program has a military component, and says the enrichment is for fuel for a Tehran reactor that makes medical isotopes. It worries it would not get the uranium back if it sends it overseas. Nuclear chief Salehi said Iran would readily stop the enrichment if the West were to give it the fuel. Salehi told al-Alam that the offer is still open, and that once Iran receives the fuel it will stop the enrichment. Western countries, in particular the United States, say the original deal was not meant to be modified and are pushing for further U.N. sanctions. U.S. Defense Secretary Robert Gates says there is still time for sanctions to work. Meanwhile, with tensions over the standoff rising, Iranian Defense Minister Ahmad Vahidi said Iran has begun production of two types of unmanned aircraft with both surveillance and attack capabilities. Vahidi noted that the drones can carry out assaults with high precision. Meanwhile, Iranian Air Force commander Hesmatollah Kassiri was quoted as saying that Iran is working on a new air defense system. The commander said Russia has been slow to deliver its S-300 missiles as agreed, but that Iran's domestically-built system will be as powerful or even stronger. Iran frequently announces major advances in its military, nuclear and space programs. The latest advances have not been independently confirmed. .
