WASHINGTON – The United States is buying 32 metric tons of Iranian heavy water, a key component for one kind of nuclear reactor, under the terms of last year’s landmark nuclear deal.
The State Department said a sales agreement would be signed on Friday at a meeting in Vienna of officials from the six countries that
negotiated the deal. Terms of the sale, under which the Energy Department will buy the Iranian heavy water from a subsidiary of the UN atomic watchdog, were not disclosed. Heavy water is not radioactive but has research and medical applications and can also be used to produce weapons-grade plutonium. The department said the heavy water will be stored at the Oak Ridge National Laboratory and then resold on the commercial market for research purposes.
