Behrouz Kamalvandi, a spokesperson for Iran’s Atomic Energy Organization, also warned that Iran could enrich uranium up to 20 percent, which is just a step below weapons-grade level.
The spokesman, Behrouz Kamalvandi, spoke to journalists at Iran’s Arak heavy water facility. He acknowledged that Iran has already quadrupled its production of low-enriched uranium — which can be used in a nuclear reactor, but not in a bomb.
Under terms of the nuclear deal, Iran can keep a stockpile of no more than 660 pounds of low-enriched uranium. Kamalvandi said that given Iran’s recent decision to quadruple its production of low-enriched uranium, it would pass the 660-pound limit on July 27.
The United Nations nuclear watchdog, the International Atomic Energy Agency, said last month that Iran still remained within its stockpile limits.
Kamalvandi said Iran needs 5 percent enrichment for its nuclear power plant in southern Iranian port of Bushehr and it also needs 20 percent enrichment for a Tehran research reactor. The nuclear deal had limited Iran to enriching uranium only to 3.67 percent, which is enough for power plants and peaceful purposes.
But after America’s pullout and escalated sanctions, Tehran set a July 7 deadline for Europe to come up with better terms for the deal, or it would take additional steps away from the accord, likely seeing it boost enrichment further.
Following the announcement on Monday, Israeli Prime Minister Benjamin Netanyahu called for more sanctions if Iran were to break the uranium stockpile limit.
“Should Iran deliver on its threats, the international community will have to implement, immediately, the pre-set sanctions mechanism,” Netanyahu said.
John Bolton, the Trump administration’s national security adviser, seemingly before Iran announced its plans on Monday, told the Washington Free Beacon the U.S. is willing to talk to Iran, but noted, “It’s a very precarious situation.”
Bolton said the Iranians are “acting as if it’s the Obama administration and that they don’t really fear American capabilities. … They are in deep economic trouble in Iran as a result of the president’s termination of the nuclear deal and the reimposition of sanctions.”
Enriching a supply of uranium means boosting its concentration of the type of uranium that can power a nuclear reaction. That type, or isotope, is called U-235. Enrichment basically means stripping away atoms of another isotope, called U-238.
When uranium is mined, it typically has about 140 atoms of this unwanted isotope for every atom of U-235. Refining it to a purity of 3.67 percent, the level now allowed by the nuclear deal, means removing 114 unwanted atoms of U-238 for every atom of U-235.
Boosting its purity to 20 percent means removing 22 more unwanted isotopes per atom of U-235, while going from there to 90 percent purity means removing just four more per atom of U-235, he noted. Ninety percent is considered weapons-grade material.
That means going from 20 percent to 90 percent is a relatively quicker process, something that worries nuclear nonproliferation experts. Iran maintains its nuclear program is for peaceful purposes.
Iran reached its nuclear deal with world powers in 2015, agreeing to limit its enrichment of uranium in exchange for the lifting of economic sanctions. Since President Trump took office, the U.S. has steadily stripped away at the accord. Trump pulled America out of the deal in May 2018.
