| DURING ANY EVENT THAT RESULTS IN THE MAJOR LOSS OF EMERGENCY OFFSITE |
| RESPONSE CAPABILITY." |
| |
| "WEATHER CONDITIONS HAVE DETERIORATED DRIVING CONDITIONS PREVENTING MULTIPLE |
| PERSONNEL FROM REACHING THE PLANT. BASED ON THESE RESULTS AND PRESENT |
| WEATHER CONDITIONS, IT IS DOUBTFUL THAT THE EMERGENCY RESPONSE ORGANIZATION |
| WOULD BE FILLED WITHIN THE REQUIRED TIME. THUS, THIS NOTIFICATION [IS] |
| BEING MADE." |

EVENT TEXT

| LICENSEE DETERMINED THAT THE CCW SYSTEM MAY NOT MEET ITS REQUIREMENT TO |
| OPERATE FOR 7-DAYS WITHOUT MAKE-UP FOLLOWING A SEISMIC EVENT |
| |
| "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 TS SURVEILLANCE |
| EXCEEDED IT 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 SHUT DOWN |
| 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.. |
| |
| "UNIT 3 IS IN MODE 1 AND UNAFFECTED BY THIS CONDITION." |
| |
| THE LICENSEE INFORMED THE NRC RESIDENT INSPECTOR. |
