Iran confirmed on Saturday it was having to remove nuclear fuel from the reactor of its only nuclear power station, signalling more problems for the Russian-built Bushehr plant after decades of delay.
Iran's nuclear envoy Ali Asghar Soltanieh told the ISNA news agency that Russian engineers who built the plant on Iran's Gulf coast had advised that the fuel be unloaded for tests. The plant's head said it was being removed for safety reasons.
"Based on Russia's request to run tests and technical measures, the fuel will be unloaded from the core of the reactor and will be returned to it after completion of the tests," Soltanieh said.
No details were given on the nature of the technical concerns but a senior Iranian official said earlier this month that suggestions that the Stuxnet computer worm had caused harm to the 1,000 megawatt Bushehr reactor should be investigated.
That was after Russia's NATO ambassador said the computer virus could have triggered a nuclear disaster on the scale of the 1986 nuclear accident at Chernobyl in Ukraine, then part of the Soviet Union.
The International Atomic Energy Agency (IAEA), which mentioned the fuel problem in a confidential report seen by Reuters on Friday, would supervise the unloading procedure, Soltanieh said.
"Safety is paramount and has the priority over speed for the start-up of this power plant," Bushehr's manager, Hossein Derakhshandeh, told the official IRNA news agency.
Bushehr was started by Germany's Siemens in the 1970s, before Iran's Islamic revolution and has been dogged by delays. Fuel was loaded into the reactor four months ago but a January deadline for it to start producing electricity was missed.
Further delays could be an embarrassment not only to Iranian politicians who have made Bushehr the show-piece of Tehran's peaceful nuclear ambitions, but also for Russia which would like to export more of its nuclear know-how to emerging economies.
Hamid-Reza Katouzian, head of Iran's parliament's energy committee, blamed Russia for the delays. "The Russians' repeated breach of promise and irresponsibility in the Bushehr project continue unabated," he told Sharq daily.
"Although Iran has spent one and half times more than it should have on the Bushehr power plant, there is still no news of the commissioning of the plant and its power generation."
