PYONGYANG, North Korea, Jan. 29 (UPI) -- Activity has been detected at North Korea's Yongbyon Nuclear Scientific Research Center for the first time in five months, suggesting a possible attempt to restart the plutonium production reactor.
According to the U.S.-Korea Institute at Johns Hopkins' School of Advanced International Affairs, satellite imagery taken between Dec. 24 and Jan. 11 indicated increased activity. Over the course of that period, snow-melted areas on roofs at the complex enlarged and steam was visible near the turbine building.
