TEHRAN, Feb. 16 (Xinhua) -- Iran's advanced centrifuges for enriching uranium and Arak heavy-water reactor are the main topics of the upcoming nuclear talks, an Iranian nuclear negotiator said on Sunday.
"In nuclear talks in Vienna, we have difficult job to do... Using new and advanced centrifuges as well as Arak heavy-water reactor are among the most important topics to reach a final agreement," the nuclear negotiator, Hamid Ba'idinejad, was quoted as saying by official IRNA news agency.
"Without doubt, we will not accept not to replace the existing centrifuges with the new and advanced ones," Ba'idinejad said, adding that "We are also earnest about keeping Arak heavy-water reactor."
However, Iran is ready to consider suggestions for removing concerns over the heavy-water reactor which the West suspects might produce Plutonium for weapon purposes, he said.
Iran and world powers, or the P5+1 group including the United States, Russia, China, France, Britain and Germany, are set to hold the next round of nuclear talks in the Austrian capital of Vienna on Feb. 18 to discuss a comprehensive nuclear agreement.
On Jan. 20, Iran and the powers started the implementation of an interim deal clinched in Geneva on Nov. 24, 2013.
Under the deal, Iran suspended its 20 percent-uranium enrichment and started the process of diluting and oxidizing its 196-kg-stockpile of 20-percent enriched uranium in exchange for a partial relief of the sanctions imposed on its energy and financial sectors.
