Subject: PLANT SHUTDOWN DUE TO FEEDWATER CHEMISTRY

Discussion:

On November 24, 2002, both units were placed in Hot Standby due to high
sodium and phosphates in the steam generators.  The licensee determined
that the elevated sodium and phosphates were caused by the wrong
corrosion inhibitor being added to each unit's feedwater system.  The
corrosion inhibitor, intended for use in the plant service water system,
broke down under normal operating temperatures releasing sodium and
phosphates.  The licensee has flushed the steam generators through a
demineralizer to clean up the steam generators and the feedwater system
on both units.

Currently, both units are in Mode 5 with a cooldown to 120 degrees F in
progress.  Based on vendor and industry recommendations, the licensee
will perform three drains and refills on both unit's steam generators.
