BALTIMORE, Jan 8, 2009 -UniStar Nuclear Energy, a strategic joint venture of Constellation Energy (NYSE: CEG) and EDF Group, today announced that the initial acceptance review phase is now complete for the first wave of UniStar's proposed fleet of advanced nuclear power plants in the United States. The milestone was achieved with the U.S. Nuclear Regulatory Commission's (NRC) recent announcement that it has accepted and docketed PPL's combined license (COL) application for a U.S. Evolutionary Power Reactor (U.S. EPR) at PPL's proposed Bell Bend site near Berwick, Pa.

PPL, a UniStar partner, submitted its application to the NRC on Oct. 10, 2008. "Achieving this important regulatory milestone for all four projects was a primary goal for UniStar during 2008, and we congratulate PPL on its recent accomplishment," said George Vanderheyden, president and chief executive officer of UniStar. "Having four of four projects under technical review by the NRC clearly demonstrates UniStar's continued leadership and momentum as we work to develop the next generation of nuclear power plant technology to support our nation's future energy needs and clean air objectives." .

In addition to UniStar's significant regulatory progress in 2008, Vanderheyden noted that public support has been strong for the proposed UniStar projects, especially in states where the projects are in a more advanced phase.

"As I attended public meetings in Maryland and New York, I was impressed by the depth and breadth of public support for the new reactors," said Vanderheyden. "We continue to hear from community leaders who are keenly aware of our excellent record related to safety and reliability, and welcome the economic and environmental benefits of these proposed nuclear plants."

On Dec. 18, 2008, UniStar announced the NRC's acceptance and docketing of its application for a proposed plant in Scriba, N.Y., adjacent to Constellation Energy's Nine Mile Point Nuclear Station.

In 2007, UniStar submitted its first, or "reference" application, for a proposed reactor in Maryland. The three subsequent applications, including one by AmerenUE for a proposed U.S. EPR in Missouri, leveraged the experience gained by UniStar in preparing the Calvert Cliffs application. NRC review of the applications is expected to take 36 to 42 months from the time the applications were submitted.

UniStar and its partners have not made a final decision to proceed with any of the proposed reactors. UniStar noted a final decision will not be made about its proposed plants in Maryland and New York until the company's expectations have been met regarding safety, cost, regulatory stability and bipartisan federal, state and local support.

AREVA's U.S. EPR is an evolutionary, 1,600-megawatt design based on reactors currently operating in Europe. Each of the proposed plants would provide electricity to more than one million homes and is expected to create approximately 4,000 construction jobs and about 360 permanent jobs. Nuclear power is considered an essential component of a diverse mix of energy sources for its ability to reliably generate baseload electricity - power that is constant 24 hours a day, seven days a week and is not affected by weather or climate.
