Joint Comprehensive Plan of Action (JCPOA)
The JCPOA, commonly known as the Iran Nuclear Deal, was agreed on July 14, 2015, in Vienna between Iran and the P5+1 (the five UN Security Council permanent members — USA, UK, France, China, Russia — plus Germany), together with the European Union.
- Iran agreed to reduce its enriched uranium stockpile by 97% (from 10,000 kg to 300 kg) and cap enrichment at 3.67% — well below the 90%+ level needed for weapons.
- Iran's installed centrifuge count was reduced from approximately 19,000 to about 6,100 (IR-1 first-generation only) for a ten-year period.
- The Fordow enrichment facility was converted to non-nuclear use for 15 years.
- In exchange, international sanctions on Iran were progressively lifted.
- Iran's nuclear breakout time (time to acquire enough fissile material for one weapon) was extended from 2–3 months to at least one year under JCPOA.
- The US unilaterally withdrew from JCPOA in May 2018; subsequent Iranian steps have progressively dismantled the limits.
