Grand Gulf Nuclear Station is a nuclear power station with one operational GE BWR reactor (General Electric boiling water reactor). It lies on a 2,100 acres (850 ha) site near Port Gibson, Mississippi. The site is wooded and contains two lakes. The plant has a 520-foot natural draft cooling tower. As of January 2023, the plant employs 675 people.[2]

Grand Gulf's reactor is the most powerful in the US and the 7th most powerful in the world,[3] [4] with a core power of 4408 MWth[5] yielding a nominal gross electrical output of 1443 MWe.

Grand Gulf is operated by Entergy, which also owns 90% of the station through their subsidiary, System Energy Resources Inc. The other 10% is owned by Cooperative Energy.
