i 3~ *Q Portland General Electric lC Nuclear Division TROJAN NUCLEAR P1 ANT Trojan Operating Report December 1989 OPEPJd M The Plant began the month in Mode 1, at 97% power.

The Plant reached 97%

5 power on October 4 ". The Plant is presently being maintained at 97% power as a result of an administrative reduction in Reactor Coolant System Average Temperature (Tm).

This resulted from changes to the Over Temperature Delta Temperature setpoints to reflect the Plant's safety analysis assumptions. The Plant will remain at this power level until an engineering analysis is completed and changes accomplished to allow us to increase our output.

On December 6th, the Pressurizer Power Operated Relief Valves (PORV) were declared inoperable.

The Channel Calibration testing methods were not adequately testing all required electrical relays that actuated the PORVs.

The appropriate actions for the Trojan Technical Specifications were immediately taken.

A Temporary Plant Test to test the required relays was successfully completed on December 15"', and the PORVs were restored to service.

On December 12th, a review of the basis frer Chlorine Toxic Cas limits revealed that the installed inonitors could not respond within the analyzed time requirement.

The Chlorine -analysis assumes a total six second delay titue prior to 1. solation of dampers upon a moni;or setpoint of five ppm being reached. The six seconds are based on three seconds for the monitor to actuate and three seconds for the damper to close upon generation of the isolation signal.

Recent vendor information shows that our detectors can not be relied upon to react within the required three seconds. The Control Room l

was placed on recirculation and an emergency change to the Trojan Technical Specifications was performed.

In addition, new detectori. will be installed and the analysis re-preformed.

On December 21th, a Containment entry was made to look for a suspected small steam leak. The steam leak was isolated to a 'D' steam generator secondary th side upper manway.

The Plant reduced power to 30% on December 26 to affect repairs.

The repairs were completed on December 29th, and power was restored to 97% at 12:40 pm.

The Plant ended the month in Mode 1, at 97% power.

MAINTENANCE Significant maintenance completed during this period includes:

Repaired sic.all steam leak from the shaf t end cap on the ' D' Main Steam Check Valve.

Replaced ' D' Steam Generator Level Transmitter 548 due to excessive setpoint driftage.

Repaired Particulate Air Filter Casket which had failed and cause a partial loss of air.
