Verified
Neutral analysis
This is a verified IAEA finding supported by environmental sampling; the enrichment level represents a significant technical step toward weapons-grade material while Iran maintains it is for civilian research purposes.
Verification notes
The IAEA published an official Board of Governors report confirming the 84% enrichment finding with environmental samples collected by inspectors. This is consistent with IAEA reporting over the past year showing a progressive increase from 60% to 84%.
