Key indicators
| Indicator | Value | Notes | Source note |
|---|
| Highest reported enrichment | Up to ~60% U-235 (reported) | Not confirmed at weapons-grade (~90%) in public IAEA-verified channels for all stocks; press and some state reporting cite higher claims. | Iran statements + secondary reporting; IAEA sampling gaps |
| Estimated breakout time | ~1–3 months | Analytic range using declared + inferred stocks; widens when verification weakens. Not a countdown to a weapon. | Analyst models; see methodology |
| Reported enriched stockpile | Multi-tonne LEU + smaller higher-enriched bands | Public totals mix forms (hexafluoride, oxide) and enrichment levels; not additive without chemistry-grade detail. | IAEA where available; else estimates |
| Key facilities tracked | 6 declared / focal sites | Fordow, Natanz, Esfahan, Arak, Bushehr, plus conversion/R&D nodes as reported. | IAEA + open imagery / press |
| IAEA verification confidence | Limited / incomplete | After June 2025 strikes and access restrictions, several lines of verification were interrupted or deferred. | IAEA Director General reports |
| Latest material update | 2026-02-27 | Safeguards report cycle referenced on this page (editorial pass). | IAEA reporting timeline |
Quick summary
This page tracks Iran’s nuclear program as a status board: enrichment ceilings, breakout-time estimates, facility condition, and what the IAEA can still verify directly after strikes and access limits. The highest enrichment widely cited in open reporting sits far above civilian needs (~60% U-235 class), while weapons-grade is higher still. Breakout time here means an analytic estimate of time to enough fissile material for one bomb’s worth under narrow assumptions — not a deployed weapon. Many numbers carry different confidence labels; after mid-2025, uncertainty widened because verification was incomplete.
Current nuclear status snapshot
| Metric | Value | Meaning | Confidence | Source | Updated |
|---|
| Highest enrichment level (public baseline) | ~60% U-235 reported | Highly enriched uranium far above civilian power needs; weapons-grade is typically ~90%. | iran_reported | Iran + IAEA where corroborated | 2026-03 |
| Estimated breakout time | ~1–3 months (range) | Time to produce enough fissile material for one device under narrow technical assumptions — not delivery or weaponization. | analyst_estimate | Analyst consensus band | 2026-04 |
| Reported enriched stockpile | Large LEU + HEU-class tails (ranges) | Feedstock that shortens breakout if further enriched or reconfigured. | uncertain_access | IAEA + estimates | 2026-02 |
| IAEA access status | Partial / contested | Some inspections proceed; others deferred. Agency has flagged inability to fully close diversion questions. | iaea_verified | IAEA DG reports | 2026-02 |
| Inspection continuity | Gaps at sensitive sites | Physical access and continuity of knowledge interrupted around strikes and diplomacy. | iaea_verified | IAEA | 2026-02 |
| Monitoring / cameras | Reduced at key nodes | Online monitoring not equivalent to full design-information verification. | open_source | IAEA + press | 2026-01 |
| Fordow operational state | Damaged (surface); underground uncertain | IAEA noted visible craters after June 2025 strikes; full underground damage could not be fully assessed at that time. | uncertain_access | IAEA + imagery | 2025-07 |
Key facilities
Fordow
Location: Near Qom
Role: Deeply buried enrichment plant
Status: Strike damage (surface); underground assessment incomplete
Confidence: uncertain_access
Last update: 2025-07
IAEA reported visible craters and expected significant damage; underground extent was not fully verified immediately after events.
Natanz
Location: Isfahan province
Role: Large-scale enrichment complex
Status: Operating history disrupted; centrifuge halls targeted historically
Confidence: open_source
Last update: 2026-02
Repeated sabotage and strikes in prior years; current throughput inferred from sparse public data.
Esfahan (conversion / fuel cycle)
Location: Isfahan
Role: Conversion and fuel-related processes
Status: Active in declared cycle; verification patchy
Confidence: iran_reported
Last update: 2026-01
Feeds enrichment complexes; fewer public imagery hits than Fordow/Natanz.
Arak / Khondab
Location: Markazi province
Role: Heavy water / reactor pathway
Status: Declared redesign path; plutonium route secondary to enrichment headlines
Confidence: iaea_verified
Last update: 2025-11
Still relevant for 1GWth-class plutonium potential under long timelines.
Bushehr
Location: Persian Gulf coast
Role: Power reactor (Russian-built)
Status: Safeguarded power generation; not the same as enrichment breakout
Confidence: iaea_verified
Last update: 2026-01
Civilian power reactor under IAEA safeguards — distinct from weapons timelines.
Centrifuge R&D / assembly
Location: Multiple sites
Role: Advanced machine assembly & testing
Status: Open-source tracking of tunneling / industrial expansion
Confidence: open_source
Last update: 2026-03
Quality of machines affects breakout speed more than headline centrifuge counts alone.
FAQ
What is Iran’s current enrichment level?
Public reporting and Iranian declarations have pointed to uranium enriched up to roughly 60% U-235 — far above commercial reactor fuel, though weapons-grade is typically near 90%. Verification completeness varies by site and time period.
What is Iran’s estimated breakout time in 2026?
Open analyst bands often cite on the order of one to a few months for enough fissile material for a single device under technical assumptions. That range widens when stocks and centrifuge performance are less certain.
What can the IAEA still verify directly?
The Agency continues some safeguards activities, but after strikes and access disputes it has publicly stated it cannot fully close certain diversion questions without additional access, reporting, and cooperation.
What is the status of Fordow?
After June 2025 strikes, the IAEA described visible surface damage and expected significant damage; it also noted that underground damage could not be fully assessed at that time.
What is the status of Natanz?
Natanz remains a central enrichment complex with a long history of sabotage and military action. Current operational rates are inferred from limited public data and should be read with medium confidence at best.
Is Iran already at weapons grade?
The widely discussed public ceiling in recent years has been near 60%, not the ~90% often associated with weapons-grade HEU, though uncertainty rises when verification is incomplete.
What changed after the 2025 strikes?
Physical damage, monitoring gaps, and diplomatic friction reduced transparency. Breakout estimates and stockpile charts on this page explicitly widen uncertainty bands for that period.
What is the difference between breakout time and weaponization?
Breakout time usually refers to fissile material production. Weaponization covers warhead design, testing, and delivery systems — typically treated as additional years of work in open-source assessments.
