AIN’T IT GRAND?  @Entergy's Grand  Gulf  Nuclear Station is the first & only nuclear power plant to produce electricity in Mississippi. It’s the largest single-unit nuclear power plant in the U.S., churning out more than 1,400 megawatts of power in the state! Grand Gulf Nuclear Station Unit 1 first connected to the grid on this day in 1984. 📷: @EntergyMS
