Has Iran Achieved a Nuclear Weapons Breakout Capability? Not Yet, But Soon.
From ISIS, David Albright, Jacqueline Shire, and Paul Brannan shine some much-needed light on what Iran’s low-enriched uranium (LEU) stockpile actually means for a supposed “breakout capability.”
In essence, Iran’s stockpile of 630 kg of enriched uranium hexafluoride cited in numerous media accounts actually contains only about 425 kilograms of enriched uranium, (with the rest being fluorine.) In order to develop a weapon, ISIS estimates Iran would need 700-800 kg of pure LEU. Therefore, Iran needs to produce another 275-375 kg to achieve a true breakout capability.
