Advanced PWR reactor technology developed by Mitsubishi Heavy Industries has been selected by TXU for new nuclear generation capacity.
TXU, which has sparked headlines recently over its decision to abandon plans for new coal-fired generation, plans to file applications for combined construction and operating licenses using US-APWR technology for 2-6 GW.
The applications will cover multiple sites, including Comanche Peak which has two units in operation. The filings would facilitate commercial operation of the units starting from 2015 to 2020.
TXU formally notified its reactor selection to the US Nuclear Regulatory Commission (NRC) and launched the preparation of Combined License (COL) application.
The US-APWR is based on a 1,538 MW APWR planned for Units 3 and 4 of the Tsuruga Power Station in Japan, MHI says. Improvements include the world's highest level of thermal efficiency at 39%, a 20% reduction in plant building volume, 24 months fuel cycle length, and greater economy by increasing capacity to 1,700 MW. MHI is planning to construct the US-APWR in cooperation with the Washington Group. A formal application for Design Certification will be conducted through the end of 2007, MHI says.
