MONTHLY NARRATIVE REPORT OF OPERATION AND MAJOR MAINTENANCE EXPERIENCE This report describes the operating and major maintenance experience for the month of January, 1987. This narrative report was prepared by the plant staff and is submitted in accordance with Section 6.9.1.7 of the Units 1 and 2 Technical Specifications.

On January 1, 1987 Unit 1 started the month at 30% power while performing startup tests following the first refueling outage. Unit 2 started the month with power at 85%.

On January 2, 1987 Unit 1 separated from the PGandE system and entered Mode 3 due to insulation smoldering under the HP turbine. Unit 2 reduced power to 55% to search for leaking condenser tubes.

On January 4, 1987 Unit 1 entered Mode 2.

Unit 2 returned to full power after plugging leaking condenser tubes.

On January 5, 1987 Unit 1 entered Mode 1 and synchronized to the PGandE system and increased power to 30%. Unit 1 i

then experienced a turbine trip and a reactor trip due to a leaking electrohydraulic oil fitting

'i under a turbine stop valve FCV-143 and subsequent loss of turbine generator electrohydraulic fluid level and pressure.

On January 6, 1987 Unit 2 reduced power to 55% to search for leaking condenser tubes and then returned to full power after plugging leaking condenser tubes.

On January 7, 1987 Unit 1 entered Mode 2.

Unit 2 reduced power to 55% to search for leaking condenser tubes and then returned to full power after plugging leaking condenser tubes.

l On January 8, 1987 Unit 1 entered Mode 1 and synchronized to the PGandE system. Unit I was then removed from the PGandE system due to the turbine generator electrohydraulic system computer software not operating properly. The computer software was reloaded into the computer and Unit I was again synchronized to the PGandE system and returned to 30% power.

On January 9,1987 Unit 1 increased power to 50%.

On January 12, 1987 Unit 2 reduced power to 50% to back flush waterboxes.

M0.RPT.

On January 13, 1987 Unit 2 returned to full power after back flushing waterboxes.

On January 17, 1987 Unit 1 increased power to 90%.

On January 18, 1987 Unit I reduced power to 50% due to a damaged turbine bearing and vibration problems on Main s

~

Feed Pump (MFP) 1-2.

On January 20, 1987 Unit 2 reduced power to 55% to search for leaking condenser tubes.

On January 21, 1987 Unit 2 returned to full power.

On January 26, 1987 A spurious signal from Containment Air Particulate Monitor (RM-11) in Unit 1 caused a Containment Ventilation Isolation (CVI).

On January 30, 1987 Unit 1 increased power to 100% after returning MFP 1-2 to operation following bearing replacement and turbine balancing.

On January 31, 1987 Unit 1 ended the month with power at 100%. Unit 2 ended the month with power at 100%.

M0.RPT

Unit 1 operated this month with a unit availability factor of 83% and a unit capacity factor of 40.9%. Unit I shutdown 3 times this month, once due to insulation smoldering under the HP turbine, once due to loss of turbine generator electrohydraulic fluid level and pressure and once due to improper operation of the turbine generator electrohydraulic system computer software. Unit I reduced power 1 time this month due to MFP 1-2 turbine bearing and vibration problems.

Unit 2 operated this month with a unit availability factor of 100.0% and a unit capacity factor of 93.1%. Unit 2 reduced power 5 times this month, 3 times to search and plug leaking condenser tubes, I time to search for leaking condenser tubes arsi 1 time to backflush waterboxes.

No challenges to the steam generator safety valves or pressurizer power operated relief valves were made.

No significant safety related maintenance was performed on Unit 1 or Unit 2.
