1Municipal Solid Waste net generation is allocated according to the biogenic and non-biogenic components of the fuel; however, all Municipal Solid Waste summer capacity is classified as Renewable
* = Absolute percentage less than 0.05.
- = No data reported.
Notes: Totals may not equal sum of components due to independent rounding.
Other: Blast furnace gas, propane gas, other manufactured and waste gases derived from fossil fuels, non-biogenic municipal solid waste, batteries, chemicals, hydrogen, pitch, purchased steam, sulfur, tire-derived fuel, and miscellaneous technologies.
Other Renewable: Wood, black liquor, other wood waste, biogenic municipal solid waste, landfill gas, sludge waste, agriculture byproducts, other biomass, geothermal, solar thermal, photovoltaic energy, and wind.

Operator: Entergy Arkansas

Location: Arkansas Nuclear One power plant is located on a 1,100-acre site near Russellville.

Construction Cost: $2.522 billion (2007 USD)2

Reactor Descriptions: Unit 1 is a Babcock & Wilcox two-loop pressurized water reactor. Unit 2 is a Combustion Engineering two-loop pressurized water reactor.

Cooling System: Unit 1 uses water from Lake Dardanelle for cooling in a once-through system. Unit 2 also draws water from the lake but supplements the cooling with a 553 feet high natural draft cooling tower.
