The UN nuclear agency is expected to make a new attempt soon to advance its investigation into Iran’s nuclear program, the diplomats said.
According to Reuters, there was no immediate comment from the IAEA, the Vienna-based UN agency.
Early last month, IAEA Director General Yukiya Amano announced that Iran has implemented three of five transparency steps that it was supposed to by August 25 under a confidence-building deal it reached with the UN body back in 2013.
The Vienna-based UN body, however, noted that Iran has been slow in providing information on the two issues that are part of the IAEA's investigation, namely the alleged experiments on explosives with possible military application, and studies related to calculating nuclear explosive yields.
The Islamic Republic has already provided the IAEA with the necessary answers to all questions on the issues related to so-called Exploding Bridge Wire (EBW) detonators.
EBW detonators are seen to have the potential for military applications. Iran insists that allegations of any such utility of that device in the country’s nuclear program are baseless, and has offered to help clear up ambiguities in this regard.
Iran has always dismissed suspicions that its nuclear program might have military dimensions, stressing that its program is solely for peaceful energy purposes.
