The council has given Tehran until February 21 to halt the sensitive nuclear work. But spokesman Mohammad Ali Hosseini told a weekly news conference that "suspension is unacceptable," and that there is "no ground" for it.
Hosseini said there is "no legal and logical justification" for suspension.
Hosseini's comments came a day after Supreme Leader Ayatollah Ali Khamenei said that the country's disputed nuclear program is its "future and destiny."
State television reported on February 17 that Khamenei had lashed out at critics who say the nuclear drive could cost Iran too much, saying the country's huge oil and gas reserves "would not last forever."
U.S. officials have repeatedly accused Iran of secretly trying to develop nuclear weapons, and the International Atomic Energy Agency (IAEA) has criticized Tehran for obfuscation and said it has not seen convincing evidence to persuade them that Iran's nuclear program is solely peaceful.
