now iran is the self-sufficient with its nuclear program

Iran now produces everything it needs for the nuclear fuel cycle, making its nuclear program self-sufficient, the head of the country's Atomic Energy Organization told state media Sunday.The step displays Iran's determination to master nuclear technology without outside help, including by enriching its own uranium, just a day before world powers meet Iranian officials in Geneva in another attempt to persuade them to freeze that work.
The Islamic republic has begun producing yellowcake, Ali Akbar Salehi told Press TV.
Yellowcake, an intermediate stage in processing uranium, is a uranium oxide concentrate which is then heated to remove impurities, the International Atomic Energy Agency says.
Iran had been importing it, Salehi said, but is now mining it and processing it within the country.
The United States and its allies fear that Iran is trying to produce a nuclear bomb. Iran denies it.Nuclear chief Ali Akbar Salehi said the uranium ore concentrate, known as yellowcake, was produced at the Gachin uranium mine in southern Iran and delivered to the uranium conversion facility in the central city of Isfahan for reprocessing.
He added that the message to those meeting with Iran in Geneva on Monday and Tuesday was that they cannot stop Iran's nuclear work.
Salehi's announcement came just a few days before Iran is to continue stalled nuclear talks with the so-called P5 plus 1 countries -- Germany and the permanent members of the U.N. Security Council: the United States, China, Russia, France and the United Kingdom.
The talks are set to take place in Geneva, Switzerland, on Monday and Tuesday, said a spokeswoman for Catherine Ashton, the European Union's foreign policy chief.
The spokeswoman said the goal of the talks is to end Iran's nuclear enrichment program.It has been more than a year since the Islamic state has had formal discussions with the P5 plus 1.
Iran has been under stiff sanctions over its continuation of uranium enrichment.
Two Iranian nuclear scientists were targeted by bombers on Monday, leaving one dead.
Iran blamed Israel, the United States and the United Kingdom's spy agencies for the attacks, which killed Majid Shahriari and injured Fereydoun Abbasi.But Salehi said Sunday that the "assassination of Iranian scientists will not hamper our progress."
