O HOPE CREEK GENERATING STATION MONTHLY OPERATING
SUMMARY
FEBRUARY 1987 Hope Creek entered the month operating at 100%
reactor power producing a daily average of 1925 MWe-Net.
The unit operated at essentially full load until February'8 at which time load was reduced to 40% to accomplish preplanned control rod swapping and Reactor Recirculation Pump Motor Generator Set maintenance.
The unit returned to 100% power on February 9 and operated at full load until a
shutdown was initiated on February 11 due to reactor coolant system unidentified leakage exceeding the Technical Specification allowable value of 5.0 gpm (Actual leakage was just over 5 gpm).
A drywell entry was made at approximately 20% reactor power in an attempt to identify and repair the leak.
The origin of the leak was found to be a weld joint on the
'A' Reactor Recirculation Pump Discharge Valve body drain line (3/4" pipe).
Since the Technical Specifications prohibit reactor operation with any Reactor Coolant Pressure Boundary leakage, the unit shutdown was continued.
The Rod Sequence Control System " locked up" during the ensuing controlled shutdown due to high a Xenon concentration adversely impacting the prescribed shutdown control rod sequence.
In response operators manually scrammed the unit and actions were undertaken to repair the subject weld.
After successful
- repair, the reactor was restarted on February 14 and following maintenance on a Secondary Condensate Pump, the unit returned to 100% power on February 17.
An automatic reactor scram occurred on February 24 during the performance of an I&C test procedure.
The test involved verifying the functionality of Reactor Level 8 trip signals to the main and Reactor Feed Pump turbines.
An actual main turbine trip was inadvertently initiated during the test, causing a reactor scram.
All required plant systems performed as expected.
The unit remained shutdown through the end of the month as repairs were made to Main Steam Line Isolation Valve electrical junction boxes and solenoid valves.
