North Anna Power Station

North Anna Power StationNorth Anna generates 1,892 megawatts from its two units — enough electricity to power 450,000 homes. Unit 1 began commercial operation in June, 1978 and Unit 2 followed in December 1980.

North Anna is located in Louisa County in central Virginia, northwest of Richmond. The facility was named after the North Anna River, which was dammed to form the 9,600-acre Lake Anna reservoir and the 3,400-acre Waste Heat Treatment Facility, used to provide cooling water for the station.

The Lake Anna reservoir and the Waste Heat Treatment Facility have become a popular outdoor recreational area, whose shoreline is dotted with homes, cabins. There are a number of marinas, campgrounds and a large state park on the Lake Anna reservoir.

Emergency Preparedness

Although it is highly unlikely that a nuclear emergency should occur at North Anna, this information explains what to do and where to go during an emergency.

About The Environment

Continuing studies show that North Anna has very minimal effects on the environment. A radiological monitoring program has shown virtually no environmental impact from operation of the station.

Exhaustive studies of Lake Anna found plant and marine life there both abundant and healthy, and the lake has become one of Virginia's premier fishing lakes. The warm water discharge from the power station may actually be helping certain sensitive species of fish thrive during cold winter temperatures.

Water Temperatures and Levels

Lake Anna's temperatures, water levels and the station discharge water temperatures are featured in our section on the station's Waste Heat Treatment Facility (WHTF).

North Anna Power Station uses water from Lake Anna to condense steam back to water inside the station. The water is returned to the lake slightly warmer than when it was taken. The discharged water cools in a series of private cooling lagoons which comprise the Waste Heat Treatment Facility.

Construction and Use Agreement - Lake Anna and WHTF

The Construction and Use Agreement process establishes an understanding of acceptable usage between the adjacent owners to Dominion's shore land surrounding Lake Anna or the Waste Heat Treatment Facility.

The procedures are general guidelines established in the consideration of granting adjacent owners' proposals a favorable review in accordance with the local, state and federal regulations, subdivision covenants and Dominion's requirements.

Potential North Anna Unit 3 - Updates and Documentation

Reactor Technology Selected for Potential North Anna Unit 3

Dominion Virginia Power has selected GE Hitachi’s ESBWR nuclear technology for its proposed Unit 3 at North Anna Power Station. GE Hitachi has teamed with Fluor, a global construction company, as a consortium for the North Anna Unit 3 project.

Application Filed For Combined Operating License

Dominion announced on Nov. 28, 2007, that it has filed an application with the U.S. Nuclear Regulatory Commission for a license to build and operate a new nuclear reactor at its North Anna Power Station in central Virginia. If built, the new reactor would add to Dominion’s position as one of the nation’s top nuclear operators.

The application filed with the NRC is for a Combined Operating License (COL) for North Anna Unit 3.  The company has not committed to build the new unit, but wants to maintain the option to do so to meet projected skyrocketing demand for electricity in Virginia in the next decade.

Early Site Permit Issued

The Nuclear Regulatory Commission authorized its Office of New Reactors to issue an Early Site Permit (ESP) to Dominion Nuclear North Anna, LLC on Nov. 20, 2007, for the North Anna ESP site near Louisa, Va. The NRC has determined that the North Anna site is suitable for an additional reactor, allowing Dominion to maintain the nuclear option for future customers.

Dominion Completes Study, Prepares Final IFIM Report

A study was conducted as a condition of the Nuclear Regulatory Commission’s Early Site Permit and Virginia’s Coastal Consistency Certification. The study examines river flows and changes in habitat in the North Anna River under existing conditions and under proposed conditions with a new Unit 3.

2011 Earthquake Information

The two nuclear reactors at North Anna Power Station in Mineral, Va., automatically shut down following a 5.8 magnitude earthquake in Central Virginia on Aug. 23, 2011, at 1:51 p.m. ET. The epicenter was approximately 11 miles west-southwest from the station.

The North Anna units sustained no functional damage to safety related systems, components or structures because of the earthquake.
