But the report also says Tehran continues to defy UN Security Council resolutions demanding that it suspend uranium enrichment.
The report was released today to the 35-nation board of the Vienna-based UN nuclear watchdog.
The report laid out details of a workplan negotiated with Tehran to resolve remaining questions regarding Iran's nuclear program, including a timeline to resolve questions on Iran's uranium enrichment work.
The report confirms a statement released by Tehran saying that questions on Iran's past plutonium experiments and contamination from highly-enriched uranium found on equipment have been resolved.
Iran has pursued a clandestine nuclear program for almost two decades, triggering accusations that it is pursuing nuclear weapons. Iran claims its efforts are solely geared towards energy production.
