Nuclear NRC Renews Operating License for Grand Gulf Nuclear Plant GGNS is a boiling-water reactor operated by Entergy in Port Gibson, about 20 miles southwest of Vicksburg. Clarion Energy Content Directors 12.1.2016 Share The U.S. Nuclear Regulatory Commission (NRC) announced today it has renewed the operating license for Unit 1 of the Grand Gulf Nuclear Station (GGNS) in Mississippi. The license clears the way for the plant to operate into 2044. GGNS is a boiling-water reactor operated by Entergy in Port Gibson, about 20 miles southwest of Vicksburg. As part of the re-licensing process, the NRC reviewed the plant’s safety, publishing an evaluation in October. In November, it also published a supplemental statement concerning the reactor’s environmental impact. The GGNS license brings to 86 the number of commercial nuclear reactors with renewed licenses in the country, though three of these plants have since shut down. Renewal applications for another nine nuclear reactors are currently under review.
