Satellite image suggests North Korea has restarted Yongbyon nuclear reactor - U.S. group

WASHINGTON (Reuters) - Satellite imagery suggests North Korea has restarted a research reactor capable of producing plutonium for weapons at its Yongbyon nuclear complex, a U.S. research institute and a U.S. official said on Wednesday.

U.S.-Korea Institute at Johns Hopkins School of Advanced International Studies said a satellite image from August 31 shows white steam rising from a building near the hall that houses the plutonium production reactor's steam turbines and electric generators.
