HIGHLIGHTS MONTHLY OPERATING ACTIVITIES - JANUARY 1988 The reporting period began and ended with the unit in Mode 1 at 80% of rated thermal power.
Gross electrical generation was 667,470 MWH for the month.
SUMMARY
01-18-88 At 0321, 2AB Emergency Diesel failed to start from the Control Room and was declared inoperable.
Evaluation of the investigation findings determined the cause of the failure to start was a stuck open starting air valve(s).
All starting air valves were replaced since it was not known which cylinder(s) the engine was lined up to initially.
Upon removal, all 12 starting air check valves were checked and found to be operating satisfactorily.
It is likely that the stuck valve(s) was/were freed when the engine was started on a
different cylinder (due to the pressure buildup).
2 AB Emergency Diesel Generator was declared operable at 2225 on 1-18-88.

Pu is 616 65-5901 lof 1 MAJOR SAFETY-RELATED MAINTENANCE JANUARY 1988 18C ¹1 027567--ECR-536, the post accident sampling containment gas space isolation valve, would not open.
Found the coil in ASCO solenoid valve XSO-1536 to be defective.
Replaced defective coil with new coil and verified proper valve operation.
ISC ¹2 013213 Pressurizer pressure channels NPP-151 and NPP-152 indicated a 20 psig difference between channels I and II.
Channel reading in protection racks revealed that channel I read 20 PSI lower than channel II.
Found amplifier in pressure transmitter NPP-151 to be defective.
Replaced defective amplifier with new amplifier and recalibrated as per 2 THP 6030 IMP.215.
Found indicator NPP-152 to be out of specifications 10 PSIG high.
Recalibrated indicator as per 2
THP 6030 IMP.215.
Found pressure transmitter NPP-152 to be out of specifications high 3. 1%.
Recali-brated pressure transmitter PP-152 as per 2 THP 6030 IMP.215.
All three channels of pressurizer pressure now read within allowable specifications.
013531--2-VCR-10 (Ice Condenser Refrigeration Glycol Supply Header Train 'A'ontainment Isolation Valve) would not operate due to a
ruptured diaphragm.
The diaphragm was replaced and the valve tested satisfactorily.
M-2 013734 The AB Diesel Generator failed to start for a surveillance run.
A starting air valve was found to be stuck open.
All the starting air valves were replaced and the engine started satisfac-torilyy.
