Comanche Peak Nuclear Power Plant Evacuation Maps

Author: No Comments Share:

Comanche Peak Nuclear Power Plant is located in Somervell County, Texas. The nuclear power plant is located 40 miles (65 km) southwest of Ft. Worth and about 60 miles (100 km) southwest of Dallas. It relies on nearby Squaw Creek Reservoir for cooling water. The plant has about 1,300 employees and is operated by Luminant Generation, a subsidiary of Energy Future Holdings Corporation.

Construction of the two Westinghouse pressurized water reactors began in 1974. Unit 1, originally rated at 1,084 MWe, came online on April 17, 1990. Its current, 40-year operating license is valid until February 8, 2030. Unit 2, 1,124 MWe, followed on April 6, 1993 and is licensed to operate until February 2, 2033 when it has to renew its license. As of 2006 Unit 2 was the second-last power reactor to come online in the USA, followed only by Watts Bar 1.

In June 2008, the U.S. Nuclear Regulatory Commission (NRC) approved a request to increase the generating capacity of units 1 and 2 by approximately 4.5% each. Luminant Generation Co. implemented the changes during refueling outages. Unit 1 was uprated in autumn 2008 with a capacity increase of approximately 1,210 to 1,259 MWe and Unit 2, the capacity of which rose from an estimated 1,208 to 1,245 MWe, was uprated in autumn 2009.

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.

The 2010 U.S. population within 10 miles (16 km) of Comanche Peak was 30,653, an increase of 44.1 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 1,755,528, an increase of 22.9 percent since 2000. Cities within 50 miles include Fort Worth (41 miles to city center)
