Ali Akbar Salehi, head of the Atomic Energy Organization and vice president to Hassan Rouhani, said that if US President Donald Trump succeeded in dismantling the 2015 deal to curb the program, Tehran would resume uranium enrichment.
“If we have to go back and withdraw from the nuclear deal, we certainly do not go back to where we were before,” he said. “We will be standing on a much, much higher position.”
Iran stores centrifuges to enrich uranium at its underground Natanz facility, under surveillance by the UN nuclear watchdog, the International Atomic Energy Agency. Salehi said it would build a new facility at Natanz that will produce more advanced centrifuges.
“This does not mean we are going to produce these centrifuges now,” he said. “This is just a preparation. If Iran decides to start mass production of such centrifuges, we would be ready for that.”
If the nuclear deal fell apart, Iran would react in stages, Salehi said. It could enrich uranium “to 20 percent, because this is our need,” and could also increase its stockpile of enriched uranium.
