US says 5 nations clear out weapons-grade uranium
None
Officials say the US has helped five nations completely clear out their stocks of highly enriched uranium since President Barack Obama outlined his plans for securing all nuclear materials worldwide, an effort aimed at preventing atomic weapons from getting into terrorists' hands.
The top nonproliferation official at the National Nuclear Security Administration said recently that since Obama's April 2009 declaration, the US has helped about a dozen countries remove enough nuclear material to make almost 30 warheads. Global leaders are expected to use the Seoul nuclear security summit, which starts Sunday, to announce additional progress. (AP)
