Iran yesterday rejected European demands that it freeze additional parts of its atomic programme, saying it would push on with plans to build a heavy-water reactor.
"We will not accept any new obligation," foreign minister Mr Kamal Kharrazi told a news conference. "If anyone asks us to give up Isfahan industries to change yellowcake into uranium hexafluoride gas or to give up heavy-water facilities in Arak, we cannot accept such an extra demand that is contradictory to our legal rights."
Yellowcake is processed uranium ore, mined near the central desert city of Yazd. Uranium hexafluoride gas is pumped into centrifuges that enrich uranium by spinning it.
The United States says Iran is using its programme as a smokescreen for building an atomic bomb, but the Islamic Republic insists its scientists are working only on ways to meet booming domestic electricity demand.
Britain, Germany and France penned a tough draft resolution this week deploring Iran's failure to cooperate fully with the UN nuclear watchdog, the International Atomic Energy Agency (IAEA).
The document, to be debated at an IAEA board meeting starting on Monday, asked Iran to freeze its operation of a uranium conversion facility near Isfahan and reverse its decision to construct a heavy-water reactor near the central industrial city of Arak.
Mr Kharrazi said he hoped IAEA board members would resist US pressure and not only soften the resolution but also drop Iran's case.
"It is not fair that Iran's case remains on the agenda for two minor issues," he said.
