(AP) Iran sends more nuclear fuel to research reactor
Iran's nuclear chief says more domestically produced nuclear fuel has been supplied to a medical research reactor.
The 20 percent enriched uranium used in the reactor has been a key issue in talks between Iran and world powers over Tehran's nuclear ambitions. The West wants Iran to halt production of the 20 percent fuel, which is much closer to weapons grade than the level needed for energy-producing reactors.
Nuclear chief Fereidoun Abbasi says more nuclear fuel was provided Sunday to the Tehran reactor, which produces radioisotopes to treat cancer patients.
Iran inserted the first domestically produced nuclear fuel into the reactor in February.
The U.S. and its allies accuse Iran of seeking to develop nuclear weapons, a charge Tehran denies.
