Iran starts nuclear reactor, says intent peaceful

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 inside the plant with its cream-colored dome overlooking the Persian Gulf in southern Iran.

In several significant ways, the Bushehr plant stands apart from the showdowns over Iranian uranium enrichment, a process that can be used both to produce nuclear energy or nuclear weapons. It also could offer a possible test run for proposals to ease the impasse.
