Grand Gulf, Mississippi

*Reactor Canceled*

On January 9, 2009, Entergy Nuclear informed the Nuclear Regulatory Commission (NRC) that they would no longer pursue a license for a GE-Hitachi -Economic Simplified Boiling-Water Reactor (ESBWR). As a result, the NRC has suspended review of its application to construct and operate a new reactor.


On March 28, 2007, the Nuclear Regulatory Commission (NRC) approved the second Early Site Permit (ESP) in the country to Entergy Nuclear for its Grand Gulf site in Port Gibson, Mississippi, 60 miles southwest of Jackson and near the banks of the Mississippi River in Claiborne County. The site is currently home to a 1,300-megawatt reactor. The plant is 90% owned by System Energy Resources, Inc., which is a wholly owned subsidiary of Entergy.

Public Citizen, along with the Mississippi Sierra Club, the Nuclear Information and Resource Service (NIRS), and the Claiborne County, MS NAACP filed a petition to intervene against the early site permit application on a variety of contentions, but those arguments, including an environmental justice claim, were rejected by the U.S. Nuclear Regulatory Commission.

A group of nuclear utilities and reactor vendors known as NuStart Energy Development which includes Entergy Nuclear, has announced its intention to seek a permit to actually build and operate new reactors at the site. NuStart submitted an application for a combined construction and operation license (COL) on February 27, 2008. The application seeks approval to build and operate one Economic Simplified Boiling-Water Reactor (ESBWR). The GE-Hitachi reactor is not currently certified. GE-Hitachi submitted the reactor design for consideration in 2005.
