Iran Enriched Record Uranium Stockpile Amid Vienna Talks

Iran produced a record volume of highly-enriched uranium that could quickly be turned into fuel for a nuclear weapon, underscoring the urgency with which diplomats are moving to restore an agreement that would rein in the Persian Gulf nation’s program.

International Atomic Energy Agency inspectors circulated a confidential assessment of Iran’s atomic program on Monday as envoys hunkered down for an eighth week of negotiations in Vienna. Diplomats are trying to orchestrate a U.S. return and Iranian compliance with a landmark nuclear agreement that curtailed Tehran’s production of nuclear fuel in exchange for sanctions relief.

Iran managed to produce 2.4 kilograms (5.3 pounds) of highly-enriched uranium in the six weeks since saboteurs struck the country’s primary enrichment facility in Natanz, according to a 13-page restricted IAEA report seen by Bloomberg. The April 11 attack prompted Iran to begin enriching uranium to levels of 60% purity, just below the threshold normally used in bombs. Iran blamed Israel for the sabotage, while Israel has neither confirmed nor denied responsibility.

“The agency’s verification and monitoring activities have been affected as a result of Iran’s decision to stop implementation of its nuclear-related commitments,” read the report, which is the second to be published since Iran began to restrict some monitoring in February. Inspectors have lost access to key sites, including workshops where the machines are made that enrich uranium.

Iran Enriched Record Uranium Stockpile Amid Vienna Talks

Over the last three months, Iran’s stockpile of 20% enriched uranium more than tripled to 63 kilograms, while its inventory of 5% material rose 6% to about 3,141 kilograms. That’s enough uranium to produce several bombs if Iran chose to enrich to weapons grade. The country says its program is exclusively for peaceful purposes.

Negotiators in the Austrian capital are in what some say could be their final round of talks to revive the 2015 accord that former U.S. President Donald Trump abandoned three years ago. A return to the deal would force Iran to cut production capacity and reduce its uranium stockpile to below 300 kilograms of material enriched to 3.67% until 2030. In return, Tehran’s government could resume oil exports and participate in the global economy.

Diplomats seeking a return to the accord are racing to do this before Iran holds presidential elections on June 18.

Iran has yet to provide clarification to IAEA investigators about the presence of decades-old uranium traces discovered at several sites, according to a second 6-page IAEA report. Iran invited agency Director General Rafael Mariano Grossi to visit Tehran the week of June 21 to continue discussing the matter.

“The Director General is concerned that the technical discussions between the agency and Iran have not yielded the expected results and of the consequent lack of progress in clarifying safeguards issues,” read the report.
