NuStart Announces Finalist Sites for the Development of New Nuclear Reactors

LCG, September 23, 2005-- NuStart Energy Development, LLC yesterday announced that its two finalist sites for the development of new nuclear reactors are Grand Gulf Nuclear Station in Port Gibson, Mississippi and Bellefonte Nuclear Plant near Scottsboro, Alabama.

NuStart was founded in 2004 to further the development of new nuclear reactors in the United States and includes Exelon, Entergy, Southern Company, Constellation, Duke Energy, the Tennessee Valley Authority, Florida Power & Light, Progress Energy, EDF International, and two reactor vendors, GE and Westinghouse Electric.

Last May, NuStart identified a short-list of six sites for developing new nuclear reactors. With the two finalist sites now identified, NuStart plans to prepare applications to the Nuclear Regulatory Commission (NRC) for combined construction and operating licenses (COL). One application will be for a General Electric (GE) Economic Simplified Boiling Water Reactor (ESBWR) and one application will be for a Westinghouse Advanced Passive 1000 reactor. Grand Gulf, owned by Entergy Nuclear, is designated for the GE reactor design. Bellefonte, owned by the Tennessee Valley Authority (TVA), will be used for the Westinghouse design.

NuStart expects to start detailed studies on the two reactor designs in order to submit applications for the COLs by late 2007 or early 2008, with the potential for completion of a project in 2015.

One of the NuStart members, Constellation Energy, announced earlier this month that it has formed a joint venture with AREVA Inc. to develop and sell new nuclear power plants in the United States. The plants will be based upon AREVA's 1,600-MW European pressurized water reactor (EPR) that is currently being deployed in Europe. Bechtel Power Corporation will support the venture with its expertise as an architect-engineer and constructor. Constellation stated that, although it would continue to support the NuStart effort financially, it has selected AREVA's nuclear technology instead of the technologies selected by the NuStart.
