    The first round of the Iran-IAEA talks was held on July 11,during which the two sides agreed on the IAEA inspectors' visit to Arak heavy water research reactor.

    The second round was held in Vienna on July 24, in which the two parties set a date for the IAEA inspectors' visit to Arak facilities. The IAEA inspectors visited the Arak reactor on July30.

    Before then, Iran had blocked inspections from the IAEA to its nuclear sites since January this year after the UN Security Council imposed sanctions over the country's controversial nuclear program.

    The Arak reactor, located about 280 km southwest of Iran's capital, could produce plutonium as a by-product when it is completed in 2009. Yet plutonium can also be used to make nuclear bombs.

    The U.S. and other Western countries have accused Iran of trying to develop atomic weapons under a civilian cover, but Iran denies such accusation, saying it just wants to generate electricity.
