North Korea will allow a team of UN nuclear watchdog officials to visit the Yongbyon reactor it has agreed to shut down under a disarmament-for-aid deal, Japan’s Kyodo news agency said on Wednesday. The International Atomic Energy Agency (IAEA) delegation headed by Olli Heinonen is already in Pyongyang, capital of the secretive communist state, to negotiate terms for inspectors to monitor the shutdown. “Tomorrow, we’re going to Yongbyon,” Kyodo quoted Heinonen as saying. He said the team would return to Pyongyang on Friday. The reactor is the source of bomb-grade plutonium for North Korea, which conducted its first nuclear test last year.
