VIENNA (Reuters) -A new reactor at North Korea's Yongbyon nuclear complex appears to be operating for the first time, the U.N. nuclear watchdog and independent experts said on Thursday, which would mean an additional potential source of plutonium for nuclear weapons.
North Korea has for years used spent fuel from a 5-megawatt nuclear reactor at Yongbyon to produce plutonium for its nuclear arsenal but a telltale discharge of warm water from a larger light-water reactor suggests it is coming online, too, the International Atomic Energy Agency said.
