Iran says its nuclear drive is ‘irreversible’

US President Barack Obama, who is seeking tougher UN  sanctions against Tehran, acknowledged that such measures would  not necessarily work, but said sustained world pressure could  prompt Iran to revise its nuclear calculations over time.

Ahmadinejad, in a speech to mark Iran’s annual nuclear day,  called the nuclear arms reduction treaty that Obama signed with  Russia this week “a masquerade” which hid his true intentions.  “We consider nuclear weapons to be against humanity,” he said.

“Iran’s nuclear path is irreversible. The Iranian nation has  reached a new point where no power can deter it from moving full  speed ahead to reach peaceful nuclear energy,” he said at a  ceremony where he unveiled the centrifuge model from behind a  white curtain.

Western nations fear Iran is trying to develop nuclear  weapons but Tehran says its programme is entirely peaceful.

In Washington, State Department spokesman PJ Crowley said  Iran’s latest “chest thumping” about its nuclear capabilities  could strengthen the push for UN sanctions. He said a peaceful  nuclear programme would have no need for faster centrifuges.

“We have to conclude that Iran has nefarious intentions with  its nuclear programme and that’s expressly why we continue to  work with the international community on additional measures,  sanctions, to show Iran that there is a consequence for its  failure to meet its obligations,” he said.
The head of Iran’s Atomic Energy Organisation, Ali Akbar  Salehi, said the latest “third generation” centrifuges had a  separation power of 10, six times that of the first generation.

But it was not clear when the new machines would be  introduced into full-scale enrichment.

“In the near future we will be ready to inject gas into this  (third generation) centrifuge,” Salehi told Iranian state TV.

The centrifuges Iran uses now are adapted from a 1970s  design and have been prone to breakdowns. Tehran has been  testing new models for several years at a site which is under  the watch of the International Atomic Energy Agency (IAEA).

“This is not unexpected and given what Obama is doing, I  think they are really trying to show that they are getting past  the sanctions,” said David Albright, director of the Institute  for Science and International Security in Washington.

“The real issue is, are they able to build these in the  thousands or … in the tens, and when are they going to be  installed? The other question is, do they work well?”
