| "On 06/02/99 at 1630 CDT, the Plant Shift Superintendent (PSS) was notified  |
| that numerous sprinkler heads were corroded, affecting 16 sprinkler systems  |
| in C-337 and one system in C-333, such that the ability of the sprinklers to |
| flow sufficient water was called into question.  Subsequently, these         |
| sprinkler systems were declared inoperable, and TSR-required actions         |
| establishing roving fire patrols were initiated.  This deficiency was        |
| detected during scheduled system inspections conducted by Fire Protection    |
| personnel.  Currently, functionality of the sprinkler heads has not been     |
| fully evaluated by Fire Protection personnel, and the remaining cascade      |
| buildings are currently being inspected, and if necessary, this report will  |
| be updated to identify any additional areas.                                 |
|                                                                              |

| FAILURE OF 13 HIGH PRESSURE FIRE WATER SPRINKLER SYSTEMS TO MEET SYSTEM      |
| OPERABILITY REQUIREMENTS  (24-Hour Report)                                   |
|                                                                              |

|                                                                              |
| "On 08/10/99 at approximately 1600 hours, the Plant Shift Superintendent     |
| (PSS) was notified that 13 sprinkler systems associated with the High        |
| Pressure Fire Water (HPFW) system were not capable of meeting system         |
| operability requirements.  This condition was discovered as a result of an   |
| engineering review of individual sprinkler heads that had previously been    |
| identified as exhibiting corrosion around the valve seat.  The engineering   |
| review was conducted following the discovery that similar corrosion problems |
| experienced at the Paducah Gaseous Diffusion Plant resulted in sprinkler     |
| heads being unable to actuate at normal pressure.  An initial screening of   |
| PORTS sprinkler heads known to exhibit corrosion was conducted, and systems  |
| where the potential for two or more adjacent heads to be corroded were       |
| inspected.  This identified 11 systems in the X-333 and 2 systems in the     |
| X-326 that did not meet the sprinkler system operability requirement that no |
| two adjacent sprinkler heads be inoperable."                                 |
|                                                                              |
| "The PSS declared the affected sprinkler systems inoperable, and TSR         |
| required actions were completed.  Further inspections of sprinkler systems   |
| are planned.  This report will be updated if additional sprinkler systems    |
| are determined to be inoperable."                                            |

| An Unusual Event was declared at 2155 EDT due to an unplanned loss of        |
| greater than 75% of the control room safety system annunciators for longer   |
| than 15 minutes. The licensee reported that the annunciators are currently   |
| inoperable, and that additional panel walkdowns are being performed. The     |
| unit is currently stable in Hot Standby following a reactor trip earlier     |
| today (see EN 36104). The NRC resident inspector has been informed, and is   |
| in the control room.                                                         |

| The plant conditions are improving and the plant is stable in Hot Shutdown.  |
| The annunciators have been restored.  The previous problem with 480 VAC      |
| busses on Event #36104 has been found to be related to the loss of the       |
| annunciators.  Further evaluation is ongoing and the licensee expects to     |

| At the Big Rock Point Restoration Project, some smoldering embers in a       |
| pipeway of the recirculation pump room generated smoke.  The Charlevoix      |
| Township fire department responded to site, but the on site fire brigade was |
| able to take care of the problem.  The problem was due to main steam pipe    |
| cutting activities heating the pipe insulation cloth coverings to the point  |
| of generating embers.  There was no fire and no entry into emergency         |
| classification.                                                              |

| MICROFILTRATION SYSTEM pH PROBES DISCOVERED TO BE OUT OF TOLERANCE           |
|                                                                              |
| "On 8/31/99 at 1200 hrs, the Plant Shift Superintendent was notified that a  |
| previously discovered X-705 Microfiltration System (MFS) pH probe out of     |
| tolerance condition likely existed during a time period when the MFS was in  |
| operation. The out of tolerance condition was in a non-conservative          |
| direction and previously discovered during a routine weekly surveillance on  |
| 8/27/99. An evaluation to determine the condition existed while the MFS was  |
| in operation was initiated at that time. Engineering suspected that the      |
| probe calibration may have been affected when the probes were exposed to a   |
| high pH solution on 8/23/99. Subsequent discussion with the probe            |
| manufacturer confirmed that a high pH solution could affect probe            |
| calibration. As a result, it was concluded that the out of tolerance         |
| condition likely existed from approximately 8/23/99 to 8/27/99.              |
|                                                                              |
| "The out of tolerance condition affected 2 of the 3 pH probes (2 out of 3    |
| logic required to activate the safety system). The as found data for the 2   |
| probes indicated they would actuate at 6.73 pH and 6.65 pH, which is below   |
| the 7 pH required setpoint. A review of the MFS operational history          |
| indicated that the MFS pH was maintained above a 7 pH during the time the    |
| probes are suspected to have been out of tolerance."                         |
|                                                                              |

| "This notification is for San Onofre Units 2 and 3 and is being made In      |
| accordance with 10CFR50.72(b)(1)(ii)(B).                                     |
|                                                                              |
| "Southern California Edison is in the process of implementing a change to    |
| the radiation monitoring system at Units 2 and 3. To complete this change,   |
| SCE installed a temporary panel in the control room area and removed the     |
| original panels and some cable wraps. On August 31,1999, shortly before      |
| midnight, licensee personnel noticed that several cables for Train A, Train  |
| B, and Train X (e.g., various low voltage electrical power cables and        |
| instrument signal lines) appeared to not meet the separation criteria of     |
| Regulatory Guide 1.75, 'Physical Independence of Electrical Systems.'        |
| Several of the affected cables provide actuation for Engineered Safety       |
| Features (e.g., control room isolation and containment purge isolation). The |
| Updated Final Safety Analysis Report for Units 2 and 3 indicates these       |
| systems comply with IEEE-297, 1971, 'Criteria for Protection System for      |
| Nuclear Power Generating Stations' which is referenced by Regulatory Guide   |
| 1.75. Consequently, at 1526 PDT, SCE concluded this condition was reportable |
| in accordance with 10CFR50.72(b)(1)(ii)(B) as a condition 'outside the       |
| design basis of the plant'.                                                  |
|                                                                              |
| "Shortly after identifying this condition, control room operators (1) placed |
| Train A of the Control Room Emergency Air Cleanup System in service, and (2) |
| closed and removed power from the containment minipurge valves. SCE          |
| determined that this condition has only existed since August 27, 1999. SCE   |
| has also confirmed that the affected components remained capable of          |
| performing their intended safety functions and, therefore concludes the      |
| safety significance of this occurrence is minimal."                          |
|                                                                              |
| The NRC resident inspector has been informed of this notification by the     |
| licensee.                                                                    |
