Iran begins enriching uranium to 60 per cent, its highest level ever

  • Although 60 per cent is higher than any level Iran previously enriched uranium, it is still lower than weapons-grade levels of 90 per cent
  • Iran insists its nuclear programme is peaceful but its detractors say Tehran had a military nuclear programme until the end of 2003

Iran has begun enriching uranium to its highest-ever purity, edging close to weapons-grade levels, as it attempts to pressure negotiators in Vienna during talks on restoring its nuclear deal with world powers after an attack on its main enrichment site.

A top official said only a few grams an hour of uranium gas would be enriched up to 60 per cent purity – triple its previous level but at a quantity far lower than what the Islamic Republic had been able to produce. Iran also is enriching at an above-ground facility at its Natanz nuclear site already visited by international inspectors, not deep within underground halls hardened to withstand air strikes.

The narrow scope of the new enrichment provides Iran with a way to quickly de-escalate if it chooses, experts say, but time is narrowing. An Iranian presidential election looms on the horizon as Tehran already threatens to limit international inspections. Israel, suspected of carrying out last Sunday’s sabotage at Natanz, also could act again amid a long-running shadow war between the two Middle East rivals.

Mohammad Bagher Qalibaf, Iran’s parliament speaker, announced the higher enrichment on Twitter.

“The young and God-believing Iranian scientists managed to achieve a 60 per cent enriched uranium product,” Qalibaf said. “I congratulate the brave nation of Islamic Iran on this success. The Iranian nation’s willpower is miraculous and can defuse any conspiracy.”

The head of the Atomic Energy Organization of Iran, the country’s civilian nuclear arm, later acknowledged the move to 60 per cent. Ali Akbar Salehi told Iranian state television the centrifuges now produce 9 grams an hour, but that would drop to 5 grams an hour in the coming days.
