Iran's uranium enrichment program is at a critical point, both technically and politically, as of February 2026. Below, I summarize the current situation, levels, stockpiles, facilities, and recent developments.
Enrichment Levels and Meanings
Uranium enrichment increases the proportion of the fissionable U-235 isotope:
3–5% → Normal nuclear power plant fuel (low enriched uranium – LEU)
20% → Intermediate level (used for research reactors, medical isotope production)
60% → Highly enriched uranium (HEU) – very close to weapons production (critical threshold for breakout)
90%+ → Weapons-grade uranium (WGU)
Iran enriches up to 60%, a level highlighted by the IAEA as the only non-nuclear weapons state. Current Stockpile Status (End of 2025 – Beginning of 2026)
According to the latest IAEA reports and statements (data from May-June 2025 and subsequent estimates):
60% enriched uranium stockpile: Pre-war (June 2025) it was approximately 408–440 kg. This amount could theoretically produce enough weapon-grade material for 9–10 nuclear bombs if further enriched (approximately 25 kg of WGU per bomb is assumed).
Following the US and Israeli attacks in June 2025:
The enrichment facilities in Natanz, Fordow, and Isfahan were heavily damaged.
Enrichment activities were officially halted (official Iranian statement).
However, a large portion of the 60% stockpile is lost/in an unknown location as it was moved before the attack (the IAEA last confirmed its location on June 10, 2025).
As of February 2026, Iran does not appear to be producing new stockpiles, but the current stockpile remains a major concern.
