Iran says it can enrich uranium to 90% purity – weapons grade – if needed

Iran has been breaching the deal in several ways after the United States withdrew from the agreement in 2018, including by producing 20% and 60% enriched uranium.

DUBAI  – Iran said on Wednesday it could enrich uranium up to 90% purity — weapons grade — if its nuclear reactors needed it, but added it still sought the revival of a 2015 deal that would limit its atomic program in return for a lifting of sanctions.

President Hassan Rouhani’s remark is his second such public comment this year about 90% enrichment — a level suitable for a nuclear bomb — underlining Iran’s resolve to keep breaching the deal in the absence of any accord to revive it.

The biggest obstacle to producing nuclear weapons is obtaining enough fissile material – weapons-grade highly enriched uranium or plutonium – for the bomb’s core. Iran says it has never sought nuclear weapons. “Iran’s Atomic Energy Organisation can enrich uranium by 20% and 60% and if one day our reactors need it, it can enrich uranium to 90% purity,” Rouhani told a cabinet meeting, Iranian state media reported.

The nuclear deal caps the fissile purity to which Tehran can refine uranium at 3.67%, well under the 20% achieved before the pact and far below the 90% suitable for a nuclear weapon.

Rouhani, who will hand over the presidency to hardline cleric Ebrahim Raisi on Aug. 5, implicitly criticized Iran’s top decision makers for “not allowing” his government to reinstate the nuclear deal during its term in office.

“They took away the opportunity to reach an agreement from this government. We deeply regret missing this opportunity,” the state news agency IRNA quoted Rouhani as saying.

Supreme Leader Ayatollah Ali Khamenei, not the president, has the last say on all state matters such as nuclear policy.

Like Khamenei, Raisi has backed indirect talks between Tehran and Washington aimed at bringing back the arch foes into full compliance with the accord. Former U.S. President Donald Trump quit the deal three years ago, saying it was biased in favor of Iran, and reimposed crippling sanctions on Tehran.

The sixth round of nuclear talks in Vienna adjourned on June 20. The next round of the talks has yet to be scheduled, and Iranian and Western officials have said that significant gaps still remain to be resolved.

Two senior Iranian officials told Reuters that president-elect Raisi planned to adopt “a harder line” in the talks after taking office, adding that the next round might resume in late September or early October.

One of the officials said many members of Iran’s nuclear team might be replaced with hardline officials, but top nuclear negotiator Abbas Araqchi would stay “at least for a while.”

The second official said Raisi planned to show “less flexibility and demand more concessions” from Washington such as keeping a chain of advanced uranium enrichment centrifuges in place and insisting on the removal of human rights and terrorism related U.S. sanctions.

Trump blacklisted dozens of institutions vital to Iran’s economy using laws designed to punish foreign actors for supporting terrorism or weapons proliferation.

Removing oil and financial sanctions is essential if Iran is to export its oil, the top prize for Tehran for complying with the nuclear agreement and reining in its atomic program.
