As of April 14, 2026, Iran's uranium enrichment activities are in a state of "high enrichment, high stockpiles, low transparency," with its 60% enriched uranium stockpile already possessing the "critical capability" to cross the nuclear threshold in the short term.

📊 Stockpile Size and Enrichment Level
High-enrichment stockpiles: According to assessments by the International Atomic Energy Agency (IAEA) and the U.S., Iran currently holds about 440 kilograms of 60% enriched uranium. This is a critical material just one step away from weapons-grade (90%), theoretically sufficient to produce several nuclear weapons.
Medium-low enrichment reserves: Additionally, Iran has about 1,000 kilograms of 20% enriched uranium and approximately 8,500 kilograms of low-enriched uranium below 5%. The total amount is substantial, with a rapid industrial capacity for further enrichment.
🏭 Production Facilities and Current Status
Core facilities: The underground centrifuge facilities in Natanz and Fordow are still operational. Although some facilities were damaged in attacks in 2025, production activities have not ceased.
Inspection obstacles: Since the second half of 2025, the IAEA has been unable to conduct full inspections of key sites (such as the ruins after attacks) for over eight months. Iran restricts inspectors from entering citing "security damage and structural danger," preventing the international community from confirming the exact location of high-enriched uranium and the status of equipment recovery.
⚠️ Key Risks
"Uranium under the ruins": About 440 kilograms of 60% enriched uranium are currently buried beneath the ruins of attacked facilities, creating physical and informational barriers. This has raised concerns about Iran possibly secretly transferring or further purifying the material.
"Critical capability": Although Iran officially denies seeking nuclear weapons, its existing stockpiles, technology, and centrifuge capacity mean it is already at the "nuclear threshold"—once a political decision is made, it could theoretically break through to weapons-grade levels within weeks.
Summary: Iran currently holds about 440 kilograms of 60% enriched uranium, with production ongoing in damaged facilities, but with extremely low inspection transparency. This directly exacerbates the deadlock in U.S.-Iran negotiations and has become a core regional security risk point. #Gate广场四月发帖挑战
