SUMMARY

OF OPERATING EXPERIENCE DATE: 11-5-86 COMPLETED BY: F. J. Ulmer TELEPHONE: 503-556-3713 OPERATIONS:

The Trojan Nuclear Plant began October at full power and remained at full power throughout the month.

On October 1, 1986, at approximately 1615, the diesel driven AFW pump (P-102B) was run for routine testing. The diesel had been running for about 15 minutes when an operator discovered oil spraying from a connection near the' diesel engine turbocharger. The operator immediately shut down the diesel.

Subsequent investigation revealed the lube oil leak resulted from separation of a turbocharger lube oil line from a tee fitting.

Approximately six gallons of lube oil was lost and one turbocharger was damaged.

As a result of the diesel lube oil rupture, the affected AFW pump (P-102B) was declared inoperable. Appropriate repairs and testing were completed in 30 hours3.472222e-4 days <br />0.00833 hours <br />4.960317e-5 weeks <br />1.1415e-5 months <br />. The turbine driven AFW pump was operable while the diesel pump was out of service.

On October 21, 1986, the Trojan Maintenance Department began removing portions of the Turbine Building siding as a result of a re-evaluation of high energy line breaks in the Turbine Building. The re-evaluation demonstrated safety-related components in the Turbine Building may not be protected in the event of a high energy line break. Removing the siding reduces the pressures and temperatures experienced by the safety-related equipment to acceptable levels. This issue is under further evaluation.

On October 24, 1986, the diesel auxiliary feedwater pump failed to start during post-maintenance testing. A broken electrical lead was found in the over-crank relay which prevented the fuel racks from opening. The lead was repaired and the diesel auxiliary feedwater pump was tested satisfactorily and returned to service.

The primary-to-secondary steam generator tube leakage remained at

one-half gallon per day and the secondary condensate oxygen remained at 5 and 3 ppb for the A and B condensate trains, respectively. The reactor coolant system dose equivalent iodine concentration remained at approximately 10% of the Technical Specification limit.

MAJOR SAFETY-RELATED MAINTENANCE:

1. Removal of Turbine Building siding for high energy line break concerns. (See Above)

2. Diesel Auxiliary Feedwater pump repairs. (See Above)

Amendment #120

-The amendment rewords.the Surveillance Requirements and. Bases to reflect.

-that the-Trojan ultimate heat sink is the Columbia River with the-

. cooling tower basin serving as the backup.

' OTHER:

- During this period, the NRC fined Portland General Electric $50,000 for a Severity Level III-violation involving the inoperability of~one of the emergency core cooling system (ECCS) subsystems. On March 31,

] 1986, the flow' path for RHR system cold leg injection to two of the

four reactor coolant system loops was isolated for one hour and ten minutes in violation of. Technical Specification requirements. This event emphasized the-importance.of expediting the programs-already initiated to establish. design basis. documents.with accurate system descriptions. A second Severity Level III violation involved an incomplete inspection by a contract quality control (QC) inspector.. '

On May.13, 1986, an NRC inspector observed that a QC inspector failed to properly witness the torquing of the bolts on.the inlet flange for

, . a pressurizer-safety valve as prescribed by the established procedures.

. The NRC determined PGE's corrective action was prompt and extensive

! and no civil penalty resulted.

Included with this report are revised capacity factors based upon historical data. reflecting maximum dependable power rating values for MDC. MDC's were corrected to reflect the effects of feedwater flow' venturi fouling in calorimetric calculations-and seasonal condenser vacuum effects from January 1980 to December 1985. Also,-the maximum

- dependable capacity gross and net values were changed to 1133 19fe and 1075 MWe,-respectively, based upon summer 1986 data and the new routine adjustment for flow element fouling.
