Start-up Delayed for Finnish Nuclear Plant

LCG, January 14, 2009--The Areva-Siemens Consortium stated yesterday that the Olkiluoto 3 nuclear power plant unit is now not scheduled for completion until 2012. The initial target for completing the Finnish project was 2009.

Finnish utility Teollisuuden Voima (TVO) stated that the Areva-Siemens Consortium, the turn-key supplier of the 1,600-MW nuclear power plant, filed an arbitration request over delays and overruns in the Olkiluoto 3 project and that the completion date has been delayed until June 2012.

The power plant incorporates AREVA's European Evolutionary Power Reactor (EPR). In the United States, Areva is acting to develop a fleet of nuclear reactors using AREVA's U.S. EPR design, which is a Generation III+ design based upon AREVA's European EPR.

In December 2007, AREVA filed its design certification application for the U.S. EPR with the Nuclear Regulatory Commission (NRC), and the NRC accepted the application for review in February 2008.
