Our Plants

Our facilities are held to the highest standards by the federal government. We have multiple built-in and portable safety systems to protect the plant against extreme weather or unexpected events.

More About Our Plants 

Environmental Stewardship

The protection of our natural environment is among our highest priorities. Each facility is surrounded by thousands of acres of plants, wildlife and native plants. We are committed to being good stewards of our surroundings so that essential habitat components are maintained, and species can thrive.  Each plant in the Southern Nuclear fleet has been certified by the Wildlife Habitat Council as a wildlife habitat. The council is a non-profit international organization dedicated to protecting and enhancing wildlife habitats.

Carbon-Free Energy For Our Net-Zero Future

Nuclear energy facilities provide 77% of Alabama's carbon-free electricity and 88% of Georgia's.

Proven Reliability

Southern Nuclear operated facilities maintained an average three-year fleet capacity factor of 94% from 2016-2019. 

Efficient Technology

One uranium fuel pellet is about the size of a pencil eraser and creates as much energy as one ton of coal, 149 gallons of oil or 17,000 cubic feet of natural gas. Each nuclear reactor is fueled with over 14 million fuel pellets and is designed to operate continuously for up to two years without refueling.

Nuclear Plant Words to Know 

See All

Chain reaction — a nuclear reaction that initiates a series of subsequent reactions.

Cold shutdown — when the cooling-water temperature in the reactor is below the boiling point and the pressure is reduced to atmospheric pressure.

Coolant — a fluid, usually water, used to cool a nuclear reactor and transfer heat energy. 

Containment — the steel and concrete structure, along with the various components, that surround and isolate the reactor. 

Contamination — the presence of unsealed sources of radioactive material in a place where it is not desired.

Control rods — movable rods used to slow down or stop a nuclear chain reaction. 

Core — the central part of a nuclear reactor that contains the fuel assemblies.

Curie — the basic unit used to describe the strength of radioactivity in a sample of material.

Dosimeter — a device that can be worn and used to measure the radiation a person receives over a period of time.

Emergency Core Cooling System — an emergency system designed to return coolant to the reactor core if coolant is lost.

Emergency Planning Zone (EPZ) — the 10-mile area around the plant. This area is required to have special emergency plans.  

Fission — the splitting or breaking apart of atoms into two or more new atoms. The process releases energy and produces heat. 

Fuel assemblies — a group of fuel rods.

Fuel pellets — pencil eraser-sized uranium oxide pellets. A reactor core may contain millions of pellets.

Fuel rods — long, hollow tubes of zirconium metal that contain stacks of fuel pellets.

Half-life — the length of time it takes for a radioactive substance to lose one-half of its radioactivity.

Millirem — a unit used to measure radiation dose.

Nuclear Regulatory Commission (NRC) — the government agency that regulates the nuclear power industry.

Plume — something such as smoke, steam or water that rises into the air in a tall, thin shape.

Radiation — energy released in the form of tiny particles or electromagnetic waves. Radiation is also emitted when you have a medical x-ray.

Reactor core — the central portion of a nuclear reactor containing nuclear fuel, water and the control mechanism, as well as the supporting structure.

Reactor trip (SCRAM) — refers to the insertion of control rods into the fuel core of the reactor, stopping the fission process.

Reactor vessel — the thick steel vessel that contains the fuel, control rods and coolant. 

Roentgen Equivalent Man (REM) — common unit used for measuring human radiation doses, usually in millirem (1,000 millirem = 1 rem).

Shielding — any material, such as lead or concrete, used around a nuclear reactor to protect workers and equipment.

Spent fuel — Nuclear reactor fuel that has been used to the extent that it can no longer effectively sustain a chain reaction.

Uranium — a radioactive element found in natural ores. Uranium is the basic fuel of a nuclear reactor.
