re: at it again
From the BBC article:
It says the report was wrong to say that Iran had enriched uranium to weapons-grade level when the IAEA had only found small quantities of enrichment at far lower levels.
News article here.
The IAEA glossary definition:
uranium, highly enriched (HEU). Enriched uranium with a proportion of uranium-235 high enough for use in nuclear weapons, typically over 90% by mass.
Even if the contamination was lower than 90 percent, enrichment above about 5 percent is past that needed for nuclear power. Claiming that it isn't 90 percent bomb grade "yet" is skirting the issue. If they are enriching to double-digit levels at all, it's for bombs.
