September 15,1994
SUMMARY
OF OPERATING EXPERIFNCE Aucust 1994 The unit began the month at 100% reactor power. On August 10,1994 at 2154 the main generator tripped due to loss of main generator field voltage. The generator trip was followed by a reactor trip for loss of load. The generator loss of field voltage was caused by an intermittent failure in the Minimum Excitation Limiter (MEL) circuit causing a voltage transient from the voltage regulator circuit. The voltage regulator MEL circuit board was replaced and tested prior to restarting the unit.
The unit was returned to power and was paralleled to the grid at 1651 on August 13,1994. At 1845 on August 13,1994 a steam leak was found in the extraction steam line. The unit was shutdown starting from approximately 45% reactor power commencing at 2355. The steam leak was repaired and the unit was paralleled to the grid at 2043 on August 15,1994. During power escalation and after reaching 30% reactor power the power increase was slowed to 3% - 5% per hour due to a very low power demand from the grid. Reactor power reached 100% at 1200 on August 16,1994.
On August 23,1994 at 1645 power was reduced due to a very low power demand from the grid. The power was increased to 100% on August 29 at 1245, however, at 1420 reactor power was again decreased to approximately 52%.
The unit ended the month at approximately 52% reactor power (405 - 410 MWe net).
