Iran says will enrich uranium to 20%, a short jump from weapons-grade material

IAEA says Tehran told it move comes in order to comply with law passed by parliament, in wake of hit on nuclear scientist Mohsen Fakhrizadeh

Iran has informed the International Atomic Energy Agency that it intends to produce uranium enriched to up to 20 percent purity, well beyond the threshold set by the 2015 Vienna accord, the UN nuclear watchdog said Friday.

“Iran informed the agency of its intention to enrich uranium at a rate of up to 20 percent in its Fordo underground plant, to comply with a law recently passed by the Iranian parliament,” an IAEA spokesperson told AFP.

The letter dated December 31 “did not state exactly when this enrichment activity would begin,” the spokesperson added.

Russian ambassador to the IAEA Mikhail Ulyanov reported the information earlier on Twitter, citing a report submitted by IAEA chief Rafael Grossi to the board of governors.

“It is an additional blow,” a diplomat based in Vienna told AFP, as Tehran continues to retaliate to US sanctions by progressively abandoning limits on its nuclear activity laid down in the deal.

Iran has not enriched to such levels since it entered into the 2015 nuclear deal with world powers, which capped its enrichment at 3.67%. Tehran has recently broken that limit as the nuclear deal has disintegrated, reaching 4.5%.

Uranium enriched to 20% is far below the 90% needed to construct nuclear bombs, but the jump from 20% to 90% is actually rather quick compared to the work needed to move from 4% to 20%.

US President Donald Trump withdrew from the accord in 2018 and began imposing a host of sanctions against Tehran as part of a so-called maximum pressure campaign aimed at buckling Iran and convincing it to agree to a more favorable agreement, in Washington’s eyes.

But Iran has not done so, instead choosing to enrich uranium to numbers far beyond what the deal allowed. The Islamic Republic’s stockpile of enriched uranium is more than 2.4 tons, 12 times the JCPOA limit, though still less than the more than eight tons Iran had enriched before signing the deal.

Since the assassination in late November of Iranian nuclear physicist Mohsen Fakhrizadeh, which Iran has blamed on Israel, hardliners in Tehran pledged a response and parliament passed a controversial law calling for the production and storage of “at least 120 kilograms per year of 20 percent enriched uranium” and to “put an end” to the IAEA inspections intended to check that the country is not developing an atomic bomb.

The Iranian government opposed the initiative which was also condemned by the other signatories to the accord who called on Tehran not to “compromise the future.”

Iran has indicated some willingness to return to compliance with the agreement if the US, under incoming president Joe Biden, lifts the sanctions that were put in place after Trump’s withdrawal.

Biden has vowed to re-enter the nuclear agreement if Iran first returns to compliance with it. He has also expressed a desire to negotiate a “longer and stronger” follow-up agreement that would extend the time-limited provisions on the JCPOA, while also addressing Iran’s missile program and curbing the influence of Tehran’s regional proxies.

Iran has rejected any such negotiations.

The remaining countries that signed the agreement with Iran — Germany, France, Britain, China and Russia — have been trying to keep it from collapsing after the unilateral withdrawal of the United States in 2018.

In late December the countries agreed to “positively address” the possibility of a US return to the accord. Germany’s foreign minister urged Iran not to waste what he called a final window of opportunity.

The three European powers have expressed hope that with the change of administrations in Washington, the US could be brought back into the deal, whose goal is to prevent Iran from developing a nuclear bomb — something Tehran insists it doesn’t want to do.

“We are standing at a crossroads today,” Germany’s Maas told reporters in Berlin, adding that the deal’s survival or otherwise will be determined in the coming weeks and months.

British Foreign Secretary Dominic Raab said that he “made it absolutely clear Iran must not implement the recently announced expansions to its nuclear program. To do so would undermine the opportunities for progress we hope to see in 2021.”

The deal promises Iran economic incentives in exchange for curbs on its nuclear program, but with the reinstatement of American sanctions, the other nations have been struggling to provide Iran the assistance it seeks.

Iranian Foreign Minister Mohammad Javad Zarif has said that Iran would “rapidly reverse” its violations of the nuclear accord when the United States and the three European powers “perform their duties.”

Despite Iran’s violations, the International Atomic Energy Agency has reported that Tehran continues to give inspectors full access to its nuclear sites — a key reason the JCPOA member nations say it is worth preserving.

In December, photos obtained by The Associated Press showed that Iran has begun construction on a site at its underground nuclear facility at Fordo.

Iran has not publicly acknowledged any new construction at Fordo, whose discovery by the West in 2009 came in an earlier round of brinkmanship before world powers struck the 2015 nuclear deal with Tehran.

While the purpose of the building remains unclear, any work at Fordo will likely trigger new concern. Already, Iran is building at its Natanz nuclear facility after a mysterious explosion in July there that Tehran described as a sabotage attack.

“Any changes at this site will be carefully watched as a sign of where Iran’s nuclear program is headed,” said Jeffrey Lewis, an expert at the James Martin Center for Nonproliferation Studies at the Middlebury Institute of International Studies who studies Iran.

The IAEA as of yet has not publicly disclosed if Iran informed it of any construction at Fordo.

Under the 2015 nuclear deal, Iran agreed to stop enriching uranium at Fordo and instead make it “a nuclear, physics and technology center.”

“This location was a major sticking point in negotiations leading to the Iran nuclear deal,” Lewis said. “The US insisted Iran close it while Iran’s supreme leader said keeping it was a red line.”

Since the deal’s collapse, Iran has resumed enrichment there.
