Iran announced two new projects Tuesday to ramp up its nuclear program, including a plan to expand the country's ability to extract and process uranium.
This announcement comes just days after Tehran and six world powers failed to reach an agreement limiting Iran's nuclear program.
Western nations have "tried their utmost to prevent Iran from going nuclear, but Iran has gone nuclear," Iranian President Mahmoud Ahmadinejad said in a speech. He warns even Western opposition will not slow Iran's nuclear work.
"They caused restrictions and issued threats, thinking that the Iranian nation cannot achieve nuclear energy...the best way for you is to cooperate with Iran," he said.
Experts say the uranium could potentially be used for atomic weapons. Iran denies Western accusations that it is seeking a nuclear weapons capability, claiming it only wants nuclear reactors for electricity and medical applications.
"We have started the design of a 10-megawatt reactor and the process for determining the location is under way," said Iranian atomic energy chief Fereydoun Abbasi-Davani, ISNA, the country's state-run news agency reported.
Meanwhile, Israel and other nations warn Iran intends to build nuclear weapons.
