Iran Nears an Atomic Milestone

Edging on the brink of a bomb’s worth of fuel is seen as a tactic to pressure the Biden administration into agreeing to a fast renewal of the 2015 nuclear deal.

WASHINGTON — Iran has come within roughly a month of getting enough material to fuel one weapon of mass destruction , crossing a threshold which will raise pressure on the us and its allies to enhance the terms of a possible deal to revive the 2015 nuclear agreement.

Experts studying new data contained in reports last week by the International nuclear energy Agency, the United Nations’ atomic inspection group, say that by enriching fuel in recent months to close bomb-grade levels, Tehran has gained the potential to supply the fuel needed for one atomic warhead within a month approximately , under the foremost extreme timeline. Federal officials who have seen classified estimates are prevented from discussing official assessments but conceded in background conversations that they believed it might take Iran only a couple of months.

Manufacturing an actual warhead — one that would fit atop an Iranian missile and survive the fiery re-entry into the atmosphere, a technology the Iranians were actively studying 20 years ago — would take considerably longer. Iran continues to insist it’s no desire for a nuclear arsenal.

Nonetheless, Iran has not been this on the brink of a weapon capability since before President Obama agreed to the 2015 nuclear accord. That agreement forced the Iranians to ship quite 97 percent of their fuel out of the country, and therefore the us said it might take a minimum of a year for Iran to succeed at “breakout,” the term nuclear experts use to define a race to create a bomb’s worth of atomic fuel.

Now, quite three years after President Donald J. Trump withdrew from the treaty, a slow and steady Iranian effort to revive the country’s capabilities appears to possess succeeded.

A report issued on Monday by the Institute for Science and International Security, a personal group that focuses on analyzing the findings of the United Nations agency, concludes that a race over the summer to complement uranium at 60 percent purity — slightly below bomb grade — has put Iran during a position to supply the fuel for one bomb in “as short together month.” A second weapon’s worth of fuel, it says, might be produced in but three months, and a 3rd in but five.

But a lead author of the report, David Albright, cautioned on Friday that Iran’s actions signaled an attempt by the new government of President Ebrahim Raisi to hunt new terms, more favorable to Iran, in negotiations over restoring the 2015 deal that Mr. Trump rejected. There are no formal negotiations since June, a month before Mr. Raisi, a conservative Iranian jurist, won the presidential election. American officials say they need been expecting that he will seek to start out the negotiations anew, demanding much more sanctions relief for Iran.

“We need to take care ,” Mr. Albright, the institute’s head, said Friday at a press conference , “not to allow them to scare us.”

Biden administration officials haven’t commented on the atomic agency’s reports, which was distributed on a confidential basis to member nations but has been widely circulated in recent days. On Friday, asked about Iran during a visit to Germany, Secretary of State Antony J. Blinken acknowledged that Iran’s progress had been so rapid that restoring the old deal might soon make no sense.

“I’m not getting to put a date thereon ,” he told reporters, “but we are becoming closer to the purpose at which a strict return to compliance” with the old deal “does not reproduce the advantages that agreement achieved.”

He said that “as time goes on and as Iran continues to form advances in its nuclear program, including spinning more sophisticated centrifuges, enriching more material, learning more, there’s some extent at which it might be very difficult to regain all of the benefits” of the restrictions Iran agreed to 6 years ago. “We’re not at that time yet, but it’s getting closer,” he added.

The next few weeks are considered critical. The opening of the United Nations General Assembly is traditionally a flash for back-room diplomacy, especially on Iran, and officials of the new Iranian government, including the new secretary of state , Hossein Amir Abdollahian, are expected to form debut appearances. Considered a hard-liner, the 56-year-old Mr. Amir Abdollahian has indicated a willingness to renew the agreement — but on terms that the new government can say are vastly improved.

Outside experts say that both Iran and North Korea , which fired a replacement aircraft on Sunday that demonstrated a capability to avoid missile defenses, see this as a flash to check the Biden administration.

“There’s an eerie similarity between what we’re seeing in Iran with enrichment and in North Korea with the aircraft test,” said Rose Gottemoeller, a former limitation official in several administrations who now works at Stanford University . “They’re both trying to line the negotiating table in their favor because the Biden administration finally turns to them.”

On Sunday, Iranian officials reached a short lived agreement with the director-general of the International nuclear energy Agency, Rafael M. Grossi, to let the agency reset monitoring devices that help measure the progress of the country’s nuclear program. In recent months, agency inspectors are blinded in their efforts to watch some facilities, a growing source of concern to American officials, who fear that nuclear material might be diverted.

The accord heads off an instantaneous inspection crisis, assuming the inspectors are allowed to realize access to their cameras and other equipment and obtain them operating again. But it doesn’t address the country’s drive to revive its uranium production — and to complement at levels far higher, and so far closer to bomb-grade material, than it did before 2015.
