State television quoted Mottaki as saying that Iran has "three options -- enrich the fuel ourselves, buy it directly, or exchange our uranium for fuel."
A plan drawn up by the IAEA after talks between Iran and major powers calls for Tehran to ship most of its low-enriched uranium abroad for further enrichment and conversion into fuel.
Iran had been due to give its response to the deal by October 23 but it has so far given only an initial reply, which Iranian media say requested amendments to the plan.
Meanwhile, Britain's "The Guardian" newspaper reported that the IAEA has asked Tehran to explain evidence suggesting its scientists have experimented with an advanced nuclear warhead design.
The West accuses Iran of covertly trying to create a nuclear weapon. Tehran denies the charge, saying its nuclear activities are peaceful.
