Iran’s sole nuclear power plant undergoes emergency shutdown

TEHRAN, Iran (AP) — Iran's sole nuclear power plant has undergone an unexplained temporary emergency shutdown, the country's state TV reported.

An official from the state electric company Tavanir, Gholamali Rakhshanimehr, said on a talk show that aired on Sunday that the Bushehr plant shutdown began on Saturday and would last "for three to four days." Without elaborating, he said that power outages could result.

This is the first time Iran has reported an emergency shutdown of the plant in the southern port city of Bushehr. It went online in 2011 with help from Russia. Iran is required to send spent fuel rods from the reactor back to Russia as a nuclear nonproliferation measure.

The report came as top diplomats said that further progress had been made at talks Sunday between Iran and global powers to try to restore a landmark 2015 agreement to contain Iranian nuclear development that was abandoned by the Trump administration. They said it was now up to the governments involved in the negotiations to make political decisions.

Earlier in the day, Tavanir released a statement saying that the Bushehr nuclear plant was being repaired, without offering further details. It said the repair work would take until Friday.

In March, nuclear official Mahmoud Jafari said the plant could stop working since Iran cannot procure parts and equipment for it from Russia due to banking sanctions imposed by the U.S. in 2018.

Bushehr is fueled by uranium produced in Russia, not Iran, and is monitored by the United Nations' International Atomic Energy Agency.
