Press TV- The spokesman for the Atomic Energy Organization of Iran (AEOI) says that Tehran has transferred an amount of its surplus heavy water to Oman for commercial purposes.

"In view of the progress of talks with several foreign firms and countries to purchase heavy water, some quantities of Iran's surplus production has been transferred to Oman," said AEOI spokesman Behrouz Kamalvandi on Sunday.

He added that further amounts of surplus heavy water will be sent to Oman in the future.

Earlier in the month, the International Atomic Energy Agency claimed in its quarterly report that Iran�s stocks of heavy water had slightly exceeded the 130-ton level set out in last year�s nuclear deal, known as the Joint Comprehensive Plan of Action (JCPOA).

Iran and the five permanent members of the United Nations Security Council � the United States, France, Britain, Russia and China � plus Germany signed the JCPOA in July 2015 and started implementing it in January 2016. Under the JCPOA, Iran undertook to put limitations on its nuclear program in exchange for the removal of nuclear-related sanctions imposed against Tehran.

On Friday, Kamalvandi stressed that Iran has remained committed to its JCPOA obligations, including those concerning its heavy water stockpiles.
