Russia says due to technical reasons it will not start a nuclear reactor at Iran's Bushehr atomic power station. The Eergy Minister Sergei Shmatko said the launch will not happen by the end of the year. He said the Bushehr decision was purely technical and that Russia would fulfill its contractual obligations to Iran.<br/>Russian President Dmitry Medvedev said after meeting with US President Barack Obama that Moscow is not completely happy about the pace of dialogue between Iran and the international community over Tehran's nuclear programme. Russia started deliveries of nuclear fuel for Bushehr in late 2007, a step both Washington and Moscow said removed any need for Iran to have its own uranium enrichment programme.<br/>Russia last year completed delivery of fuel under a contract estimated to be worth about one billion dollar. Russia says the plant is purely civilian and cannot be used for weapons development, as Iran will return all spent fuel rods to Russia.
