"Studies for the location of 10 uranium enrichment facilities have ended," Salehi said, adding "the construction of one of these facilities will begin by the end of the (current Iranian) year ( that ended in March 2011) or start of next (Iranian) year."
Currently, Iran's Natanz enrichment facility is enriching uranium to a level of 20 percent and another facility around Qom, Fordo, is under construction.
Iran had said on Sunday it will not stop its nuclear fuel enrichment activities although Russia would provide it with the nuclear fuel needed to run its Bushehr nuclear power plant.
Head of Iran's Majlis National Security and Foreign Policy Commission said Sunday that Iran will continue the uranium enrichment process inevitably because the country needs it for its future power plants.
Asked by reporters whether Iran will continue the enrichment process after fuel is injected into Bushehr plant, Alaeddin Boroujerdi said that fuel injection and uranium enrichment are two different issues.
