The Nuclear Regulatory Commission (NRC) and the U.S. Army Corps of Engineers (USACE), Fort Worth District, completed the Final Environmental Impact Statement (FEIS) for the Combined Licenses (COL) for the proposed Comanche Peak Nuclear Power Plant Units 3 and 4. The NRC said no environmental impacts would preclude issuing the COLs for constructing and operating the proposed reactors at the site, near Glen Rose, Texas.
Luminant Generation applied for a license to build and operate two 1,500 MW Mitsubishi U.S. Advanced Pressurized-Water Reactors (US-APWR) adjacent to the existing two-unit 2,300 MW Comanche Peak nuclear power plant. Luminant submitted the application in September 2008 and supplemented the report in November 2009.
The USACE will use the information in the FEIS in making its federal permit decision in accordance with the Clean Water Act and Rivers and Harbors Act.
The NRC’s publishing the FEIS is part of the Comanche Peak COL review. Agency staff continue to compile a final safety evaluation report, which will include recommendations from the NRC’s Advisory Committee on Reactor Safeguards, an independent group of nuclear safety experts. The NRC’s five commissioners must also conduct a mandatory hearing regarding whether the staff’s review supports the findings necessary to issue the COLs. All of these items must be completed before the NRC can reach a final decision on the COL application.
