Exelon Nuclear Selects GE Hitachi's ESBWR for Texas Reactor

LCG, November 14, 2007--Exelon Nuclear, a unit of Exelon Corporation, announced Monday that it selected the GE-Hitachi Nuclear Energy (GEH) Economic Simplified Boiling Water Reactor (ESBWR) design for a new nuclear power plant in Texas. Exelon has stated that it plans to file an application with the Nuclear Regulatory Commission (NRC) in 2008, although a decision to construct the nuclear plant has not yet been made.

The planned electric generating capacity of the GEH ESBWR is 1,520 MW. The ESBWR design employs passive safety features that rely upon natural forces.

Exelon is not the first to select the GEH ESBWR. NuStart Energy, a consortium of nuclear energy companies, and Dominion are developing the reference application for the GEH ESBWR. Dominion is expected to file the Construction and Operating License (COL) application with the NRC for a single unit at its North Anna Power Station later this year. The application will support subsequent, planned COL applications, including the anticipated application by Entergy for its Grand Gulf and River Bend sites next year.

Exelon announced in June 2007 that it had selected two potential sites near the Texas Gulf Coast to construct a new reactor. The two sites are a 1,250-acre tract in Matagorda County near Palacios, and an 11,500 acre site south of Victoria.
