Nuclear Energy

NextEra Energy Resources’ parent company, NextEra Energy, operates one of the largest nuclear power fleets in the United States.



Nuclear energy provides safe, reliable and low-cost power for homes and businesses.

Growing energy demands, unpredictable fossil fuel costs and the continuing need for clean energy are among the reasons nuclear power remains an attractive source of electricity.


Clean, Reliable and Affordable

Nuclear power plants are a clean energy source because the plants don't burn any fuel to produce electricity. Nuclear power plant operation produces virtually no pollutants or greenhouse gases.



NextEra Energy Resources' nuclear portfolio includes plants in Iowa, Wisconsin and New Hampshire.

Duane Arnold Energy Center

Duane Arnold Energy Center

Located near Palo, Iowa, Duane Arnold generates about 615 megawatts of power, enough to provide electricity for more than 600,000 homes.


Point Beach Nuclear Energy Center

Point Beach

Point Beach in Two Creeks, Wisconsin produces about 1,200 megawatts of power, approximately one-sixth of the state’s electricity.


Seabroak Nuclear Station

Seabrook Station

Seabrook Station generates more than 1,250 megawatts of electricity, enough to supply 1.2 million families with power for a year.

How Nuclear Plants Work

Nuclear power plants do not burn any fuel, so there are no pollutants released into the air. In a nuclear power plant, uranium – a natural ore that has been enriched – is used. Steam is generated through a process called fission, instead of burning oil, gas or coal.

Fission happens when tiny parts of uranium, known as atoms, split. During fission, even smaller particles of the atom, called neutrons, are released. The neutrons strike more uranium atoms, resulting in the release of the heat needed to generate electricity.

There are two types of reactors in the United States:

Boiling Water Reactors (BWRs) – boil water so that it is converted to steam. The steam drives a turbine connected to a generator before being recycled back into water by a condenser and used again in the heat process.

Pressurized Water Reactors (PWRs) – keep water under pressure so it heats up but does not boil. Water from the reactor and water in the steam generator never mix.
