| LICENSEE DETERMINED THAT THE CCW SYSTEM MAY NOT  MEET ITS REQUIREMENT TO     |
| OPERATE FOR 7 DAYS WITHOUT MAKE-UP FOLLOWING A SEISMIC EVENT.                |
|                                                                              |
| THE FOLLOWING TEXT IS A PORTION OF A FACSIMILE RECEIVED FROM THE LICENSEE:   |
|                                                                              |
| "AT SAN ONOFRE, THE COMPONENT COOLING WATER (CCW) SYSTEM IS REQUIRED TO      |
| PROVIDE COOLING FOR 7 DAYS WITHOUT MAKE-UP.  CCW TRAINS 'A' AND 'B' ARE      |
| SEISMICALLY QUALIFIED; THE NON-CRITICAL LOOP IS NOT SEISMICALLY QUALIFIED."  |
|                                                                              |
| "UNIT 2 ENTERED MODE 5 AT APPROXIMATELY 0544 PST ON JANUARY 3, 1999, FOR A   |
| PLANNED REFUELING/MAINTENANCE OUTAGE.  AT 2051 ON JANUARY 4, 1999, WHILE     |
| UNIT 2 WAS IN MODE 5, SCE DETERMINED THAT ISOLATION VALVE LEAKAGE BETWEEN    |
| CCW TRAIN 'B' AND THE CCW NON-CRITICAL LOOP OBSERVED DURING A [TECHNICAL     |
| SPECIFICATION] SURVEILLANCE EXCEEDED ITS ACCEPTABLE LIMIT FOR OPERATION IN   |
| MODES 1 THROUGH 4, AND TRAIN B CCW COULD HAVE BEEN INOPERABLE PRIOR TO SHUT  |
| DOWN.  TESTS WERE PERFORMED TO ATTEMPT TO DETERMINE WHETHER THIS LEAKAGE     |
| EXISTED DURING OPERATION IN MODES 1 THROUGH 4 PRIOR TO PLANT SHUT DOWN.      |
| HOWEVER, THE TESTS WERE UNABLE TO DETERMINE THAT THE LEAKAGE DID NOT EXIST   |
| PRIOR TO SHUT DOWN.  DURING THE PAST CYCLE OF PLANT OPERATION, IF A SEISMIC  |
| EVENT WERE TO HAVE OCCURRED WHILE TRAIN 'A' WAS OUT OF SERVICE, THERE WAS A  |
| POTENTIAL FOR THE CCW TO FAIL TO MEET ITS REQUIRED 7 DAYS OF OPERATION       |
| WITHOUT MAKEUP.  THEREFORE, SCE IS CONSERVATIVELY MAKING THIS REPORT AS A    |
| NON-EMERGENCY 4-HOUR REPORT IN ACCORDANCE WITH 10CFR50.72(b)(2)(iii) - A     |
| CONDITION THAT ALONE COULD HAVE PREVENTED THE FULFILLMENT OF THE SAFETY      |
| FUNCTION OF THE CCW.                                                         |
|                                                                              |
| "CCW IS PRESENTLY CAPABLE OF PERFORMING ITS SUPPORT FUNCTION FOR SHUTDOWN    |
| COOLING IN MODES 5 AND 6.  THE ISOLATION VALVES' ACTUATORS WERE              |
| DISCONNECTED, THE VALVES WERE MANUALLY SEATED.  THE MEASURED LEAKAGE WAS     |
| WELL BELOW THE ACCEPTABLE LEVEL FOR OPERATION IN MODES 1 THROUGH 4.  THE     |
| ACTUATORS WERE RE-CONNECTED TO PROVIDE FOR REMOTE OPERATION.  THE            |
| INVESTIGATION OF THE CAUSE AND CORRECTIVE ACTIONS IS ON-GOING.               |
|                                                                              |

| THE LICENSEE IS RETRACTING THIS EVENT BASED ON THE FOLLOWING:                |
|                                                                              |
| "SUBSEQUENT DIAGNOSTIC TESTS WERE PERFORMED AND THE CAUSE OF THE LEAKAGE WAS |
| DETERMINED TO BE INSUFFICIENT SEATING LOAD FOR VALVE HV6213.  THIS VALVE'S   |
| LEAKAGE WAS ACCEPTABLE FOLLOWING ITS LAST TECH SPEC REQUIRED SURVEILLANCE    |
| TEST.  SCE WAS NOT ABLE TO DETERMINE WHEN THE VALVE SEATING LOAD CHANGED.    |
| THEREFORE, BASED ON THE GUIDANCE PROVIDED IN NUREG-1022, REV 1 THIS          |
| CONDITION IS CONSIDERED A FAILED SURVEILLANCE TEST AND FAILED WHEN FOUND.    |
| BECAUSE THE CONDITION WAS DISCOVERED IN AN OPERATIONAL MODE WHERE CCW TECH   |
| SPEC DOES NOT APPLY, THIS CONDITION IS NOT REPORTABLE."                      |
|                                                                              |

| "MAINTENANCE ACTIVITIES WERE BEING PERFORMED ON THE OVERHEAD ALARM SYSTEM TO |
| REPLACE A BATTERY IN THE 'B' SEQUENCE OF EVENTS RECORDER.  THIS ACTIVITY WAS |
| COMPLETED, WHICH THEN REQUIRED THAT DEFAULT DATA BE LOADED INTO THE          |
| RECORDER.  THIS DEFAULT DATA WAS IMPROPERLY LOADED INTO THE ACTIVE SEQUENCE  |
| OF EVENTS RECORDER  'A.'  THIS CORRUPTED IT'S DATA WHICH RENDERED THE ENTIRE |
| OVERHEAD ALARM SYSTEM INOPERABLE.  THERE ARE NOT PLANT TRANSIENTS IN         |
| PROGRESS AND ALTERNATE INDICATIONS FOR THE OVERHEAD ALARM WINDOWS ARE        |
| AVAILABLE.  ACTIVITIES ARE IN PROGRESS TO RESTORE THE SEQUENCE OF EVENTS     |

| SPECIFICATION REQUIRED SHUTDOWN.  THE STEAM DRIVEN AUXILIARY FEEDWATER PUMP  |
| HAS BEEN INOPERABLE SINCE FEBRUARY 2, 1999 AT 1225 CST PER TECHNICAL 2.5(1), |
| A 24 HOUR LIMITING CONDITION FOR OPERATION."                                 |

| A DESIGN MODIFICATION WAS PERFORMED ON THE SYSTEM AROUND JUNE 1998 WHICH     |
| INSTALLED AN ACCUMULATOR DESIGNED TO PREVENT TURBINE OVERSPEED AND           |
| OVERPRESSURIZATION OF THE DISCHARGE PIPING.  DURING SURVEILLANCE TESTING ON  |
| FEBRUARY 2, 1999, THE ACCUMULATOR FAILED TO MEET THE MAXIMUM 10 PSI DROP IN  |
| 1 HOUR  ACCEPTANCE CRITERION.  THE ACTUAL PRESSURE DROP WAS MEASURED AS 5.5  |
| PSI IN 30  MINUTES.  THE LICENSEE SUBSEQUENTLY REEVALUATED THE BASIS FOR THE |
| DESIGN MODIFICATION AND CONCLUDED THAT A CHOKED FLOW CONDITION WOULD EXIST   |
| PRECLUDING TURBINE OVERSPEED.  THE LICENSEE IS REVISING THE SURVEILLANCE     |
