U.S. to buy nuclear material from Iran

The U.S. will purchase 32 metric tons of heavy water from Iran, a key part of nuclear reactors, according to a senior administration official The official said the goal is to get the heavy water out of Iran in the same way the Iran nuclear deal urged Iran to ship its supply of enriched uranium to Russia The U.S. will spend $8.6 million for the heavy water and the U.S. official said the arrangement will probably be revenue-neutral because the Department of Energy will resell the heavy water to commercial and lab facilities in the U.S
