Planned Restart of Ontario Nuclear Reactors Gains Momentum

LCG, July 12, 2006--The Canadian Nuclear Safety Commission (CNSC) last week accepted the Environmental Assessment (EA) for the project to-restart two nuclear reactors at the Bruce A Nuclear Power Station near Kincardine in southwestern Ontario. The CNSC determined the project would have no significant adverse effects to the environment.

The two, 750-MW nuclear units commenced operations in 1977 and were shut down in 1995 and 1997 by the prior owner, Ontario Power Generation (OPG). Approval from the CNSC will be required prior to loading the reactors with new fuel and commencing full operations.

With the EA accepted by the CNSC, the restart project will gain momentum.
The work on Units 1 and 2 is scheduled to be completed by early 2008. When the work is complete, Bruce Power plans to apply to the CNSC for licenses to refuel the units and anticipates the units will return to service in 2009.

Additional investments are planned to refurbish Unit 3 when it reaches the end of its operational life and to replace the steam generators in Unit 4. In total, it is estimated that Bruce Power will invest approximately C$4.25 billion.
