NARRATIVE
SUMMARY
MONTil:
November 1992 Catawba Unit I began the month of October in end-of-cycle 6 refueling outago. The unit was originally scheduled to return to service on 9/16/92. The outage was extended by 8 days for reactor coolant system leakago at a cononseal at-the reactor vessel head and reactor coolant pump seal problems.
The outage was extended 15 days due to a steam generator tube leak.
The unit was placed on line on 10/20 at 1530 for a refueling duration of 101.75 days. The unit held at approximately 15%
power from 1724.to 10/21 at 0050 for the turbine overspeed trip test.
The unit was off-line from 0050 to 0356-for the turbine overspeed trip test.
During power escalation, the unit held at approximately 20% from 10/21 at 0720 to 1128 for steam generator
'C' leakage stabilitly.
The unit held at approximately 30% power from 1443 to 1507-for flux mapping and decreased to approximately 25% power due to the data obtained from the flux map.
The unit held at approximately 25% power from 1526 to 2000 for a flux map.
The unit held at approximately 40% power from 10/22 at 0040 to 1220 for a flux map.
The unit held at approximately 70% power from 10/22 at 2350 to 10/23 at 0300 for control valve movement testing. The unit held at approximately 80% powerEfrom-0750 to 1550 for flux mapping.
The unit reached 100% full power on 10/24 at 1120.
The unit operated at.or near 100% full power for the remainder of the month.
