PWR= Pressurized Light Water Reactor
Note: Both reactors were up rated in capacity. *Unit 1 was previously listed as 836 net MWe; Unit 2 was previously rated at 858 net MWe.

Description: Arkansas Nuclear One (ANO) power plant actually contains two reactors (the second being designated either ANO-2 or Arkansas Nuclear One unit 2). The plant is located on a 1,100-acre site in Pope County. The Dardanelle Reservoir, a lake covering 34,300 acres, is used for the plant's cooling system.

In 2001, Unit 1 had a capacity factor of 92.8 percent and supplied 6.80 billion kilowatthours of electricity. In 2002, it was shut down for much of October resulting in a drop of 233.4 million kilowatthours (3 percent) in annual output. Unit 2 was among the world leaders in capacity utilization, averaging 106.3 percent. It produced 7.99 billion kilowatthours, and slightly more in 2002. Arkansas Nuclear One is owned and operated by Entergy Arkansas, Inc.

Sources: Capacity, for purposes of this report, is the net summer capability as reported in Energy Information Administration (EIA) survey form 860, "Annual Electric Generator Report." Capacity Factor is a calculation in which the maximum possible generation (based on net summer capability) is divided into the actual generation than multiplied by 100 to get a percentage. Generation is the electricity output reported by plant owners on EIA survey form 906. Type of Unit: All U.S. commercial reactors currently in operation are one of two types: BWR (boiling water reactor) or PWR (pressurized light water reactor). The type is identified in EIA's Nuclear Power Generation and Fuel Cycle Report. Both the On-line Date and the License Expiration Date are reported annually in Information Digest by the U.S. Nuclear Regulatory Commission.
