Licenses. We have 40-year operating licenses for each of our nuclear units. We
applied to the NRC in July 2001 for extension of the Peach Bottom 2 and 3
licenses and we expect to apply for the extension of the operating license for
Dresden 2 and 3 and Quad Cities in 2003. AmerGen is reviewing the potential for
license extensions for Oyster Creek and Three Mile Island. Each requested
license extension is expected to be for 20 years beyond the current license
period. The following table summarizes operating license expiration dates for
our nuclear facilities in service.
