The team will be headed by IAEA Deputy Director Tero Varjoranta for two days of talks with AEOI officials and experts, Kamalvandi said.
The official said the IAEA has delayed responding to the information sent by Iran about two recent issues mentioned in the third stage of their cooperation agreement
One of the issues is related to alleged experiments in Marivan, and the other to papers published in Iran about neutron transports and associated modeling and calculations and their alleged application to compressed materials.
"Iran has told them (IAEA) that if they think some explosions have taken place, they should specify its location so that the country gives them access to the place,” Kamalvandi said.
The official said Iran and the IAEA's step-by-step cooperation is based on the agreement that the two sides deal with other steps only after finalizing different subjects mentioned in the previous step.
Thus, Tehran and the IAEA will not deal with other issues before concluding those related to the Marivan and neutron transport cases.
The last technical meeting between the two sides was held in November last year.
Last Monday, the IAEA verified lack of any diversion towards non-peaceful purposes in Iran’s declared nuclear material.
"Concerning safeguards implementation in Iran, the agency continues to verify the non-diversion of nuclear material declared by Iran under its Safeguards Agreement,” IAEA Director General Yukiya Amano said in an address to the agency’s Board of Governors in Vienna.
