“Breakout time”: Experts say Iran would need three to six weeks to generate enough fissile material for nuclear weapon – compared to one year timescale when Tehran was abiding by terms of 2015 accord

Enrichment: Deal caps purity to which Tehran can refine uranium at 3.67%. Iran is now enriching to various levels – highest being 60%

Centrifuges: Deal limits Tehran to using about 5,000 first generation IR-1 centrifuges – machines used to refine uranium – at Natanz. Iran now operates hundreds of advanced centrifuges at Natanz and over 1,000 IR-1s at underground Fordow site

Uranium stockpile: Tehran has just under 2.5 tonnes of enriched uranium – over 12 times more than 202.8kg limit imposed by deal.
It takes about 25kg of uranium enriched to 90% to make one nuclear bomb

Monitoring: Iran has stopped International Atomic Energy Agency – UN’s nuclear watchdog – from carrying out snap inspections at undeclared nuclear sites

Potential weaponisation
Recent production of uranium metal at Isfahan is pivotal step towards making nuclear bomb. Iran says it is working on reactor fuel
