The International Atomic Energy Agency says U.S. Energy Secretary Spencer Abraham will visit its Vienna headquarters later this month to launch a new initiative on nuclear non-proliferation. Melanie Sully has this story in the Austrian capital.
   IAEA spokeswoman Melissa Fleming confirmed top-level talks are planned on a global cleanup of all the highly enriched uranium from civilian reactors. The United States is already financing a program to repatriate weapons-grade uranium from Eastern Europe and former Soviet states back to Russia. Experts fear many of the reactors are run-down and poorly guarded making them a possible target for terrorists. At the end of last year, a U.S. -led team evacuated highly enriched uranium from an inactive research reactor in Bulgaria and flew it to Russia where it was burnt down as reactor fuel. Similar joint operations with the IAEA have taken weapons-grade uranium from reactors in Romania and Serbia. Melanie Sully for VOA news Vienna.
