A meeting of the Joint commission of Iran and a group of six world powers (five permanent members of the UN Security Council and Germany) on the implementation of the nuclear deal will be held in Vienna on July 19, the Russian Permanent Representative to the International Organizations in Vienna, Vladimir Voronkov, said.
According to Voronkov, the meeting will focus on the problems with surplus enriched uranium and compliance with the limits of heavy water stocks.
"There are two issues that need to be addressed. These are the difficulties with enriched uranium accumulated during the enrichment in the pipes and other devices. What has been discovered exceeds the allowed limit of 300 kilograms. And the second issue is heavy water," TASS cited him as saying.
Voronkov added that Russia "is dealing with the matter whether to buy" heavy water from Iran or not to make sure that Tehran remains within the limits set by the nuclear deal. He explained that "there is a fundamental desire to negotiate the issue, so far this is a question of a one-time purchase."
