Criticism: Thousands of Iranian centrifuges will keep spinning.
The deal doesn’t dismantle or close Iran’s two uranium enrichment facilities at Natanz and Fordow. It does require Iran to reduce its centrifuge inventory by two-thirds and eliminate 98% of its stockpile of enriched uranium. Iran will be allowed to keep about 6,100 centrifuges for the next 10 years and continue some enrichment work.
White House response: Iran’s inventory of centrifuges will be cut drastically from nearly 20,000, which is enough to create fuel for as many as 10 bombs. It will be left with only its oldest and least efficient models. No enrichment will be allowed at Fordow, and other activities will be restricted to producing uranium enriched to a level of 3.67%, far below the nearly 90% usually required to make a bomb.
