Evidence Grows That North Korea Has Restarted Reactor

North Korea’s 5-megawatt reactor at Yongbyon is releasing hot water, a sign operations have resumed at the facility capable of producing enough plutonium to make one nuclear bomb a year, according to a U.S. research group.

Satellite imagery taken Sept. 19 shows water being released into the Kuryong River from the reactor facility at North Korea’s main nuclear complex, according to the 38 North website, which is run by the U.S.-Korea Institute at Johns Hopkins University’s School of Advanced International Studies in Washington.
