VIENNA (Reuters) - Olli Heinonen, chief inspector of the United Nation's nuclear watchdog, set out for North Korea on Sunday to agree details on the return of IAEA inspectors to monitor Pyongyang's promised atomic shutdown.
North Korea agreed in February to mothball its Yongbyon nuclear reactor, the centrepiece of its nuclear programme and source of weapons-grade plutonium, in exchange for fuel aid and security benefits as well as a process to remove trade sanctions and Pyongyang from a U.S. list of state sponsors of terrorism.
