Luminant's Comanche Peak Steam Electric Station is Luminant's sole nuclear power plant. Located in Glen Rose, Texas, Comanche Peak welcomes visitors with an expansive visitor's center, videos and nuclear related information.
The Comanche Peak nuclear power plant is a two-unit nuclear-fueled power plant located four and a half miles northwest of Glen Rose in Somervell County and about 80 miles southwest of downtown Dallas. The plant is owned and operated by Luminant and has an operating capacity of 2,300 megawatts (two 1,150 megawatt units). The plant has approximately 1,300 employees.
Fuel
Fuel for the Comanche Peak plant is uranium dioxide, enriched to about 4.5% uranium -235. The fuel is fabricated in small ceramic pellets and the pellets are clad in zirconium tubes or fuel rods. The fuel rods are bundled together to form fuel assemblies. Each pellet of uranium fuel produces as much heat energy as 149 gallons of oil; 157 gallons of gasoline; 1,780 pounds of coal; or 19,200 cubic feet of natural gas. There are more than 18,000,000 fuel pellets in each reactor.
Cooling Reservoir
Squaw Creek Reservoir provides cooling water for the power plant. The reservoir covers 3,275 surface acres with an average depth of 46 feet and it took approximately 2 years to fill. When both units of Comanche Peak are at full power, 2.2 million gallons of water are pumped through the plants main condensers.
Miscellaneous
More than 450,000 cubic yards of concrete have been poured and more than 63,000 tons of reinforcing steel bar have been used in plant construction. The combined length of electrical conduit at Comanche Peak is more than 200 miles.
Special Programs
Educational material is available on a variety of nuclear energy topics. This includes simulated uranium fuel, plant photographs, postcards, and a series of pamphlets addressing nuclear energy issues. Speakers from the Comanche Peak site are available to meet with your group at the Visitors Center. Engineers, environmental experts, chemists, and radiation protection specialists, among others, are eager to share their information and experience with you.
