Arkansas Nuclear One
Grand Gulf Nuclear Station
In July of 1985, Grand Gulf Nuclear Station in Port Gibson,
Miss., made history by becoming the first and only nuclear power plant to
produce electricity in Mississippi. Now Grand Gulf is marking another
milestone with a power upgrade that will make it the largest single-unit
nuclear power plant in the country and fifth largest in the world. Grand
Gulf is owned and operated by Entergy Mississippi (90 percent) and South
Mississippi Electric Power Association (10 percent).
The project will be one of the largest expansions of a
nuclear power plant in U.S. history and increase Grand Gulf’s production by
more than 13 percent, bringing total output to 1,443 megawatts. The action
is part of Entergy’s overall plan to close a growing gap between the amount
of power the company produces and the amount that customers use. Today,
Grand Gulf is already the most affordable source of electricity in
Mississippi.
One of Entergy’s core values is a commitment to communities,
and Grand Gulf and its employees maintain a strong presence in Port Gibson
and Claiborne County. A recent Communitas Award for Leadership in Community
Service applauded Grand Gulf’s community efforts that include a partnership
with a local university on a health physics internship program, the
establishment of an economic development organization for the area and a
multitude of support programs for public education, the arts and low-income
customers.

Grand Gulf Nuclear Energy Prevents Emissions
Generating electricity with nuclear energy prevents the emission of
pollutants like sulfur dioxide (SO2) and nitrogen oxides (NOx) and greenhouse
gases like carbon dioxide (CO2) associated with burning fossil fuels.
During 2009, environmental emissions avoided due to nuclear power plant
operation in Mississippi included 13,382 short tons of sulfur dioxide, 7,521
short tons of nitrogen oxide and 7.95 million metric tons of carbon dioxide.
Emissions of SO2 lead to the formation of acid rain. NOx is a key precursor
of both ground-level ozone and smog. Greenhouse gases like CO2 contribute to
global warming.
Source: Emissions avoided by nuclear power are calculated using regional
fossil fuel emissions rates from the Environmental Protection Agency and plant
generation data from the Energy Information Administration.
