Iran and Russia signed a nuclear fuel agreement on 27th February, paving the way for Iran to start up its first atomic reactor. Iranian Vice President Gholamreza Aghazadeh and the head of Russia's Federal Atomic Energy Agency Alexander Rumyantsev signed the agreement at the Bushehr plant. Russia's Itar-tass news agency quotes Rumyantsev as saying the plant is scheduled to go on line at the end of 2006, with 100 tones of fuel to be delivered about six months before. A key part of the agreement obliges Tehran to repatriate all spent nuclear fuel to Russia. The International Atomic Energy Agency (IAEA) said it would keep a careful eye on Tehran's use of the fuel. The United States has accused Iran of trying to produce nuclear weapons. Tehran says its program is for peaceful purposes.
