Under the July deal, Iran agreed to reduce its number of installed centrifuges to around 6,100 from 19,000, according to the United States. Of the remaining 6,100, only about 5,100 will be used to enrich uranium.
Iran was also carrying out an annual inventory at all its enrichment sites, meaning that enrichment had stopped across the country, the report said.
"This is the first time at this point in time that none of the three enrichment plants are operating," the senior diplomat said.
Iran's stockpile of low-enriched uranium had increased by 460.2 kg in the past three months to 8,305.6 kg, the report said. Under the deal with major powers, that stockpile must be slashed to no more than 300 kg.
The senior diplomat, however, said the increase was a normal fluctuation.
"There is nothing special in that. It's the normal way," he said.
