Units

Unit One

Unit One has a generating capacity of 846 MW of electricity, and came online on May 21, 1974. It is licensed to operate through May 20, 2034.[1] Its nuclear reactor was supplied by Babcock and Wilcox.

Unit Two

Unit Two has a generating capacity of 930 MW of electricity, and came online on September 1, 1978. It is licensed to operate through July 18, 2038.[2] Its nuclear reactor was supplied by Combustion Engineering. Unit two is the only one that uses the cooling tower; Unit One releases heat back into Lake Dardanelle.

Surrounding population

The Nuclear Regulatory Commission defines two emergency planning zones around nuclear power plants: a plume exposure pathway zone with a radius of 10 miles (16 km), concerned primarily with exposure to, and inhalation of, airborne radioactive contamination, and an ingestion pathway zone of about 50 miles (80 km), concerned primarily with ingestion of food and liquid contaminated by radioactivity.[3]

The 2010 U.S. population within 10 miles (16 km) of Arkansas Nuclear was 44,139, an increase of 17.2 percent in a decade, according to an analysis of U.S. Census data for msnbc.com. The 2010 U.S. population within 50 miles (80 km) was 308,219, an increase of 13.3 percent since 2000. Cities within 50 miles include Russellville (6 miles to city center).[4]

Seismic risk

The Nuclear Regulatory Commission's estimate of the risk each year of an earthquake intense enough to cause core damage to the reactor at Arkansas Nuclear was 1 in 243,902, according to an NRC study published in August 2010.[5][6]
