At least 10 more nations are poised to agree to eliminate their stocks of highly-enriched uranium and plutonium during next month's nuclear security summit in South Korea, an organizer said Wednesday. Top leaders from 50 nations as well as four international organizations, including U.N. Secretary-General Ban Ki-moon, will attend the March 26-27 Nuclear Security Summit in Seoul, which aims to bolster international safeguards and prevent nuclear terrorism. It will be the second summit since U.S. President Barack Obama launched the global gathering in Washington in 2010.
