PPL to Use Areva's Nuclear Reactor Design in Application to NRC

LCG, December 20, 2007--PPL Corporation announced yesterday that one of its subsidiaries will submit an application for a combined construction and operating license (COL) to the Nuclear Regulatory Commission (NRC) for approval to build and operate a nuclear reactor near the Susquehanna nuclear power plant near Berwick, Pennsylvania. The application will use AREVA's U.S. Evolutionary Power Reactor (U.S. EPR) and will be submitted by the end of 2008.

Earlier this month AREVA filed its design certification application for the U.S. EPR with the NRC. The U.S. EPR is a Generation III+ design based upon AREVA's 1,600-MW, European EPR now being deployed in Europe. AREVA expects the Design Certification application will be validated by 2010, which would enable a U.S. EPR to be licensed and ready for operation as early as 2015.

PPL contracted with an affiliate of UniStar Nuclear Energy, a joint venture of Constellation Energy and The EDF Group, to prepare the application. Unistar also selected Areva 's U.S. EPR design for use in its plans to build a 1,600-MW nuclear reactor at Constellation Energy's existing Calvert Cliffs Nuclear Power Plant in Lusby, Maryland. In July Unistar filed the environmental report portion of a COL application with the NRC to build the reactor, and Unistar plans to submit the remainder of the application in early 2008.

PPL announced last June that it was considering the construction of a third reactor at its Susquehanna plant. PPL notified the NRC of its intentions and filed a request with the PJM Interconnection for preliminary transmission interconnection studies for the Susquehanna site.

The existing Susquehanna plant consists of two reactors with a combined electric generating capacity of 2,360 MW. The operating licenses for Susquehanna 1 and 2 were issued in 1982 and 1984, respectively, and the licenses for Susquehanna 1 and 2 expire in 2022 and 2024. The facility is jointly owned by PPL Susquehanna, LLC and Allegheny Electric Cooperative Inc. and is operated by PPL Susquehanna.

PPL stated that it has not yet decided to move forward with construction. In addition, given the market, construction and regulatory uncertainties, along with the large capital commitment for a nuclear project, PPL would proceed with construction only in a joint venture arrangement.
