TVA and NuStart File Application for New Nuclear Reactors

LCG, October 31, 2007--The Tennessee Valley Authority (TVA) and NuStart Energy, a consortium of nuclear energy companies, yesterday submitted an application to the Nuclear Regulatory Commission (NRC) for a Construction and Operating License (COL) to build two nuclear reactors at TVA's Bellefonte site in northern Alabama. The new units would employ the Westinghouse AP1000 design.

Members of NuStart Energy consortium are: Constellation Energy, Duke Energy, Detroit Edison (membership pending), EDF International North America, Entergy Nuclear, Exelon Generation, Florida Power & Light Company, Progress Energy,South Carolina Electric & Gas, Southern Company, TVA, GE-Hitachi Nuclear Energy, and Westinghouse Electric Co.

The AP1000 reactor incorporates passive safety features that rely upon natural forces. The NRC approved the Design Certification for the AP1000 standard nuclear plant design on December 30, 2005. Other companies that have announced the selection of the AP1000 design as the basis for additional COL applications to construct reactors include: Progress Energy, Southern Company, Duke, SCANA and Santee Cooper.

NuStart and Dominion are also developing the reference application for the GE-Hitachi Nuclear Energy (GEH) Economic Simplified Boiling Water Reactor (ESBWR), which also employs passive safety features. NuStart expects Dominion to file the application with the NRC for a single unit at its North Anna Power Station later this year, and the application will support subsequent, planned COL applications by Entergy for its Grand Gulf and River Bend sites next year.

In addition to the applications relying upon the Westinghouse and GEH designs, Unistar Nuclear, a joint venture of Constellation Energy and AREVA Inc., in July 2007 filed with the NRC the environmental report portion of a COL application to build a reactor that uses AREVA's 1,600-MW, U.S. Evolutionary Power Reactor (US EPR). The US EPR is based upon AREVA's 1,600-MW, European EPR that is now being deployed in Europe. The new reactor would be built adjacent to Constellation's existing Calvert Cliffs nuclear power plant in Lusby, Maryland.
