Iran starts nationÂ’s first reactor

Trucks rumbled into Iran's first reactor to begin loading tons of uranium fuel in a long-delayed startup touted by officials as both a symbol of the country's peaceful intentions to produce nuclear energy as well as a triumph over Western pressure to rein in its nuclear ambitions.

The Russian-built Bushehr nuclear power plant will be internationally supervised, including a pledge by Russia to safeguard it against materials being diverted for any possible use in creating nuclear weapons. Iran's agreement to allow the oversight was a rare compromise by the Islamic state over its atomic program.

Western powers have cautiously accepted the deal as a way to keep spent nuclear fuel from crossing over to any military use. They say it illustrates their primary struggle: to block Iran's drive to create material that could be used for nuclear weapons and not its pursuit of peaceful nuclear power.

Iran has long declared it has a right like other nations to produce nuclear energy. The country's nuclear chief described the startup as a "symbol of Iranian resistance and patience."

"Despite all pressure, sanctions and hardships imposed by Western nations, we are now witnessing the startup of the largest symbol of Iran's peaceful nuclear activities," Ali Akbar Salehi told reporters.

The Russian agreement to control the supply of nuclear fuel at Bushehr eased opposition by Washington and its allies. Bushehr's operations are not covered by United Nations sanctions imposed after Iran refused to stop uranium enrichment.

After years of delays in completing the plant, Moscow now claims that the project is essential to persuading Iran to cooperate with international efforts to ensure it does not develop the bomb.

UN nuclear inspectors were on hand as the first truckloads of fuel were taken from a storage site to a "pool" inside the reactor. Over the next two weeks, 163 fuel assemblies will be moved inside the building and then into the reactor core.
