THEY WANT TRADE, NOT NUKES:

Pushing past a Tuesday deadline, world powers and Iran extended negotiations for a comprehensive nuclear agreement by a week as the U.N. nuclear agency prepared to announce Tehran had met a key condition -- significantly reducing its stocks of enriched uranium that could be used for atomic weapons. [...]

As for Iran's reduction in its stockpile of enriched uranium, diplomats said the country had removed a potential hurdle that nuclear experts had been watching closely over the past several weeks.

Uranium can be used to generate energy, or as the fissile core of a nuclear weapon, depending on its enrichment level. Under the preliminary deal from November 2013, Iran agreed to cap its stockpile of lower-enriched uranium at a little more than 7.6 tons and transform any remainder into a form that would be difficult to reconvert for arms use.
