j TROJAN NUCLEAR PLANT 1
Trojan Operating Report November 1989 OPERATIONS l
The plant began the month in Mode 1, at 97% power.
The Plant i
reached 97% power on October 4th.
The plant is presently being maintained at 97% power as a result of an administrative reduction in Reactor Coolant System average temperature (Tgg ).
This resulted from changes to the Over Temperature Delta Temperature setpoints to reflect the plants safety analysis l
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 November 1",
a series of short duration alarms of Main Generator field grounds were received.
Various attempts were made to locate the source of the grounds with no success.
Monitoring equipment has been installed to monitor for grounds.
On November 8*,
a spurious high alarm on the Containment radiation monitor (PRM-1D), caused an automatic closure of the hydrogen vent Containment isolation valves.
The source of the spurious signal has not been determined.
The effected PRM and the other associated PRMs were satisfactorily retested.
PRM-1D was restored to service.
A noise suppression circuit is being installed to reduce spurious signals.
On November 13*,
the
'C' Main Steam Isolation Valve Bypass failed to close during the performance of testing.
The valve was isolated in accordance with the Trojan Technical Specifications.
On November 20*,
several problems were identified with the performance of fire protection surveillances.
All work on fie detectors and alarm supervision systems was stopped until a review of fire barrier inspections was completed.
A special task force has been formed to review past and scheduled surveillances in other areas to assure that none are missed, and to develope a program to schedule all surveillances under one program with the responsibility residing with Plant Planning and Scheduling.
On November 30", the number 1 seal water leak off flow indicator for Reactor Coolant Pump number 2 failed.
The failure was identified as a loose fuse clip.
The problem was fixed and verified not to exist on any other seal water leak off flow indicators.
The plant ended the month in Mode 1, at 97% power.
