The inspections will indeed take place," International Atomic Energy Agency director general Rafael Grossi told reporters in Japan. "We will be working on the modalities - dates, procedures, places - very soon."
The agreement signed last week said "explicitly" that the dilution of Iran's highly enriched uranium would be carried out under IAEA supervision, he added. BBC reported.
However, Iran's deputy foreign minister said access to its damaged nuclear facilities and nuclear material would only be addressed within the framework of a final deal with the US.
Grossi's comments come as US Secretary of State Marco Rubio is visiting Gulf nations to discuss the deal. On Wednesday he met UAE President Mohamed bin Zayed Al Nahyan and is due to travel to Kuwait and Bahrain.
