Thermal Images of North Korea Nuclear Plant Hold Disturbing News

North Korea may have more fuel for nuclear bombs than previously believed, according to a US think tank. The new report from 38 North analyzed thermal satellite images of the Yongbyon nuclear plant, the country's main nuclear site, and found that Pyongyang may have reprocessed more plutonium than previously thought; the images also indicated that Yongbyon could be increasing production of enriched uranium, another source of fuel for atomic bombs, though it's not clear whether the thermal activity there was due to maintenance or actual centrifuge operations. The images also showed the plant's isotope/tritium production facility is likely not producing tritium, which is used for hydrogen weapons. Reuters has more on the report. (More North Korea stories.)
