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.

PWR = Pressurized Light Water Reactor.
Note: Totals may not equal sum of components due to independent rounding.
Source: Form EIA-860, "Annual Electric Generator Report," and Form EIA-923, "Power Plant Operations Report." |
Operator: Tennessee Valley Authority (TVA)
Location and Service Territory: The Sequoyah nuclear power plant is located on a 525-acre site near Chattanooga, Tennessee.
Construction Cost: $3.455 billion (2007 USD)2
Staffing: The staff consists of 900 employees; however, up to 800 additional contractors may be brought on for refueling and maintenance outages.
Reactor Descriptions: The plant houses two, Westinghouse four-loop pressurized water reactors. Each reactor holds 193 fuel assemblies.
Cooling System: The cooling system uses a natural draft cooling tower that draws water from the Chickamauga Reservoir.
