Iran has reiterated that it is ready for fuel swap, provided it is done within the country.According to Iranian news agency ILNA, speaking in his weakly press conference foreign ministry spokesman Ramin Mehmanparast said that Iran has sent a letter to IAEA to inform that country will cooperate with IAEA if the atomic agency supplies the 20 percent nuclear fuel to Tehran research reactor. He added that Iran does not want to reduce the level of cooperation with IAEA or withdraw NPT but it does not see a necessity to increase the level of cooperation with the agency either.'
