An Iranian nuclear official says the country has transferred stocks of so-called heavy water to Oman.
A report by the International Atomic Energy Agency last week showed that Iran's stocks of heavy water -- a key component in nuclear reactors -- had reached above the 130-ton level set out in the nuclear deal signed by Tehran and world powers.
"In view of the progress of talks with several foreign firms and countries to purchase heavy water, some quantities of Iran's surplus production have been transferred to Oman," said Behrouz Kamalvandi, spokesman for Iran's Atomic Energy Organization, according to the Iranian Students' News Agency (ISNA).
Kamalvandi, speaking on November 20, did not reveal the interested foreign companies or countries. The sale of heavy water internationally is allowed under the deal.
Iran has so far sold 42 tons of heavy water to the United States and about 39 tons to Russia, reported ISNA.
There was no immediate official confirmation of the report.
