National Public Radio quotes Thomas Shea from an Atlantic Council event in a discussion on American participation in the inspection of Iranian nuclear facilities:

Thomas Shea, who spent more than two decades as an International Atomic Energy Agency (IAEA) inspector, says Iran does not accept any American inspectors today. He recently told the Atlantic Council that he hopes that will change.

“I do think that there’s a need for more Americans on the staff,” he said, pointing out that the U.S. pays a quarter of the IAEA’s $380 million annual budget. Shea says this should entitle the U.S. to have one out of four of the inspector jobs.

However, the language in the agreement says that Iran “will generally allow the designation of inspectors from nations that have diplomatic relations with Iran.”
