TEHRAN, Sept. 18 (Xinhua) -- Breakthrough is anticipated in the upcoming talks over Iran's nuclear issue, Head of Atomic Energy Organization of Iran Ali-Akbar Salehi said Wednesday.
"We will witness breakthroughs in the (nuclear) issue in the coming months," Salehi was quoted as saying by Press TV.
"As I had previously announced, we are very optimistic about the process that has started to resolve the nuclear issue, and we expect that we will see the beginning of a trend in the coming months to settle the nuclear issue," he said.
Salehi described his Monday meeting with Director General of the International Atomic Energy Agency (IAEA) Yukiya Amano as very positive, according to Press TV.
On Sept. 9, the IAEA expressed concern over the lack of up-to- date information about Iran's heavy water reactor that is currently under construction.
"The lack of up-to-date design information on the IR-40 reactor is having an increasingly adverse impact on our ability to effectively verify the design of the facility," Amano told at a meeting of UN agency's 35-nation board of governors, adding Iran should fully cooperate to clarify the "outstanding issues" over its disputed nuclear program.
IAEA's latest report showed Iran had yet to offer design details on its 40 megawatt heavy water reactor under construction in Arak.
The Western countries is increasingly concerned that the reactor could be used to produce weapons-grade plutonium and potentially to produce a nuclear bomb. However, Iran has repeatedly stated its nuclear program is peaceful and aimed at power generation, research and development.
IAEA has accused Iran of failing to comply with existing agreements, according to which Iran should offer the design information of its nuclear facilities.
Both parties will meet for the 11th round of talks on Sept. 27 in Vienna, aiming at striking a deal on a "structured approach" toward a nuclear inspection framework.
Previous talks over the past two years over the issue have yielded no substantial progress.
Western states have been long accusing Iran of developing nuclear weapon under cover of civilian nuclear program, but Iran says the suspicion is baseless and fabricated.
