UniStar Congratulates PPL on Submission of Combined License Application to NRC for Potential New Reactor

Submittal is fourth UniStar-Supported Application for AREVA’s U.S. Evolutionary Power Reactor

BALTIMORE, October 10, 2008 – UniStar Nuclear Energy, LLC (UniStar), a strategic joint venture between Constellation Energy (NYSE: CEG) and EDF Group, said PPL’s submission today of a Combined License Application (COLA) to the U.S. Nuclear Regulatory Commission (NRC) for a potential new nuclear power plant is another important milestone in the path to certainty for U.S. Evolutionary Power Reactor (U.S. EPR) projects in the United States.

UniStar leveraged its prior license-preparation experience to support PPL’s application, which seeks regulatory approval to construct and operate a potential 1,600 megawatt U.S. EPR adjacent to PPL’s Susquehanna Nuclear Plant site near Berwick, Pa.

PPL’s application is the third “S-COLA,” or subsequent COLA based on UniStar’s original “R-COLA,” or reference COLA, for a potential U.S. EPR adjacent to Constellation Energy’s Calvert Cliffs Nuclear Power Plant in southern Maryland.  It follows S-COLAs submitted in July by AmerenUE for a potential U.S. EPR adjacent to the utility’s Callaway Plant near Fulton, Mo. and in September by UniStar for a potential new reactor adjacent to Constellation Energy’s Nine Mile Point Nuclear Station in Oswego, N.Y.

“We congratulate PPL on this important milestone,” said George Vanderheyden, president and chief executive officer of UniStar Nuclear Energy. “This submission further advances UniStar’s plans to develop a standardized fleet of at least four U.S. EPRs to help meet America’s future energy needs with a clean, safe, economic and reliable source of power.”

A final decision has yet to be made to proceed with nuclear plant development at any of the four proposed U.S. EPR sites.

UniStar’s chosen technology for its proposed fleet is AREVA’s U.S. EPR, which is currently undergoing design certification review by the NRC.  The evolutionary Generation III+ design is based on technology that began in the U.S. and has evolved and been operating safely in Europe for many years.
