The official says the temporary shutdown of repairs began on Saturday and could last up to four days, which could lead to power outages.
Iran’s only nuclear power plant has been temporarily shut down for a “technical overhaul,” Iranian state television said.
An official from the state power company, Gholamali Rakhshanimehr, said in a talk show that the closure of the Bushehr plant began on Saturday and would last “three to four days.”
He added that a power outage could occur. He did not delve into it, but this is the first time Iran has reported an emergency closure of the plant, located in the southern port city of Bushehr.
It went online in 2011 with the help of Russia. Iran is forced to send spent fuel rods from the reactor to Russia as a measure of nuclear non-proliferation.
In March, nuclear official Mahmoud Jafari said the plant could stop working, as Iran cannot acquire parts and equipment from it in Russia due to US-imposed banking sanctions in 2018.
Bushehr feeds on uranium produced in Russia, not Iran, and is overseen by the United Nations International Atomic Energy Agency (IAEA).
The UN agency did not immediately respond to a request for comment on the reported closure.
Abas Aslani, a senior researcher at the Tehran-based Center for Strategic Studies in the Middle East, told Al Jazeera that the shutdown could be a blow to an Iranian energy source. strained by cryptocurrency mining.
“That [shutdown] it is more important in terms of power outages than the nuclear aspect of the facility, ”said Aslani.
“Because these days we are seeing cryptocurrency mining consuming electricity in the country and this has caused some power outages in the past.”
Construction of Bushehr on the northern shore of the Persian Gulf began under the shah of Iran in the mid-1970s.
After the 1979 Islamic Revolution, the plant was a repeated target of the Iran-Iraq war. Russia later completed construction of the facility.
The plant, located near active fault lines and built to withstand strong earthquakes, has been periodically shaken by earthquakes. There have been no significant earthquakes in the area in recent days.
