![]() ![]() Rolls-Royce was awarded a contract worth £9m ($13.7m) for replacing the plant process computer (PPC) systems for the two units of the plant in August 2013.īechtel replaced four steam generators and a reactor vessel head in unit one of the Comanche Peak in 2007. The project was, however, shelved after Luminant requested the NRC to suspend the license application review in November 2011.įluor was contracted to provide engineering, facility services, and maintenance and modifications services for the Comanche Peak NPP for a period of five years, in July 2017. It was also issued the final environmental statement (EIS) for the 3.4GW expansion project, while the license approval for both the proposed units was anticipated in 2015. Luminant applied to the US Nuclear Regulatory Commission (NRC) in 2008 for a combined license to build and operate two 1,700MW advanced pressurised water reactors (US-APWR) from Mitsubishi Heavy Industries (MHI) at the Comanche Peak site in 2008. The two units of the Comanche Peak NPP are expected to be operational until 2050. The project provided more than 10,000 jobs during the construction phase, while another 1,000 are permanently employed for the operations. The site also features an independent spent fuel storage installation (ISFSI) to store spent reactor fuel and radioactive materials in above-ground dry casks.Ĭomanche Peak nuclear power plant detailsĬonstruction works on the Comanche Peak nuclear power project were started in December 1974. The plant receives water supply from the nearby Squaw Creek Reservoir Dam. The tandem-compound four-flow type turbine generator of each unit is capable of generating 1,150MW of net electricity at 22kV, which is stepped-up to 345kV by the main transformers located on-site. ![]() The fuel assemblies in the reactor core comprise fuel rods clad with uranium-235 in the form of ceramic pellets.Įach 43.8ft-tall and 14.4ft-diameter cylindrical reactor vessel with an 8.5in-thick steel wall is placed within a 265ft-high dome-shaped containment building with 4.6ft reinforced concrete wall with 8in steel liner.Įach unit has four steam generators that are capable of producing steam at 1,000psia pressure and 285° Celsius temperature. The Comanche Peak nuclear power station comprises two Westinghouse four-loop PWR units with dry, ambient pressure (DRYAMB) containment. The plant site lies to the south-west of downtown Dallas, at a distance of 96km from Fort Worth.Ĭomanche Peak nuclear power plant make-up The Comanche Peak nuclear power plant is located on a 4,047ha-site located approximately 7km away from Glen Rose, Somervell county, Texas. Operating with an average load factor more than 88%, the power station generated more than 490TWh of cumulative electricity by the end of 2018.Ĭomanche Peak nuclear power plant location ![]()
