A fire that broke out at Iran's Natanz nuclear facility on Thursday caused significant damage, the country's atomic agency admitted on Sunday.
Behrouz Kamalvandi, spokesman for the Atomic Energy Organisation of Iran, said the fire could slow down Tehran's development and production of advanced centrifuges in the medium term.
Mr Kamalvandi said Iran would replace the damaged building with a larger one containing more advanced equipment.
The agency initially reported only that an "incident" had occurred early on Thursday at Natanz, in the desert of the central province of Isfahan.
It later published a photo of a one-storey brick building with its roof and walls partly burnt.
A door hanging off its hinges showed that there had been an explosion inside the building.
Iranian officials later suggested the fire might have been the result of a cyber attack but refused to make the cause public because of "security reasons".
Iran's nuclear chief, Ali Salehi, told the Iranian News Agency on Sunday that "various scenarios" about the incident were under investigation and the results would be announced soon.
The agency quoted Mr Kamalvandi as saying uranium enrichment was continuing far from the site of the fire.
The Natanz uranium-enrichment site, much of which is underground, is one of several Iranian complexes monitored by inspectors of the International Atomic Energy Agency, the UN nuclear watchdog.
The agency said on Friday that the fire did not ignite near nuclear materials, and that none of its inspectors was present at the time.
Less than a week earlier, there was mysterious blast at a suspected missile development centre at Parchin, east of Tehran.
Iranian officials said the explosion, which was felt in the capital about 20 kilometres away, was caused by a gas leak.

Tearful appearance
Chancellor Rachel Reeves set markets on edge as she appeared visibly distraught in parliament on Wednesday.
Legislative setbacks for the government have blown a new hole in the budgetary calculations at a time when the deficit is stubbornly large and the economy is struggling to grow.
She appeared with Keir Starmer on Thursday and the pair embraced, but he had failed to give her his backing as she cried a day earlier.
A spokesman said her upset demeanour was due to a personal matter.
