| SECURITY REPORT. FITNESS-FOR-DUTY QUESTIONED DUE TO INATTENTIVENESS. |

| * * * UPDATE 1140EST ON 1/19/00 FROM MATTHEW ARSENAULT TO S.SANDIN * * * |
| |
| THIS REPORT IS BEING RETRACTED BASED ON THE FOLLOWING: |
| |
| "On January 17, 2000, at 6:32 EST, North Atlantic Energy Service Corporation |
| (North Atlantic) submitted a 1-hour report to the Nuclear Regulatory |
| Commission pursuant to 10 CFR 73.71 regarding a Security Officer that was |
| discovered to be inattentive to duty (NRC Event Report 36596). |
| |
| "Subsequent to the report and after a thorough review, it was determined |
| that this incident was loggable and did not meet the criteria for a 1-hour |
| report. Specifically, this condition did not constitute an uncompensated |
| loss as defined in Regulatory Guide 5.62 because the original capability was |
| restored within 10 minutes of discovery of the event. Additionally, |
| consistent with the guidance provided in Generic Letter 91-03, events |
| involving inattentive security personnel can be logged if they are properly |
| compensated for in accordance with Regulatory Guide 5.62 and NUREG-1304. |
| Therefore, North Atlantic retracts the 1-hour report. This event has been |
| captured in the event log." |
| |
| The licensee will inform the NRC resident inspector. Notified R1DO |
| (Hinson). |

| LOSS OF COMMERCIAL TELEPHONE SERVICE |
| |
| The licensee reported that all U.S. West commercial telephone service to the |
| site (including the ENS) has been lost due to a problem offsite. The |
| licensee is attempting to contact U.S. West to determine the cause of the |
| problem and estimate time to restore. |
| |
| The NRC resident inspector will be informed of this event by the licensee. |

| |
| "The following event description is based on information currently |
| available. If through subsequent reviews of this event, additional |
| information is identified that is pertinent to this event or alters the |
| information being provided at this time, a followup notification will be |
| made via the ENS or under the reporting requirements of 10 CFR 50.73." |
| |
| "NOTE: THIS ENS WORKSHEET IS A FOLLOW-UP TO ENS ID 36601, PERFORMED AT 09:41 |
| MST. SINCE U.S. WEST LINES WERE AFFECTED, THE INITIAL CALL WAS MADE VIA A |
| CELLULAR TELEPHONE." |
| |
| "On January 18, 2000, at approximately 0925 MST, Palo Verde Units 1, 2, and |
| 3 determined that the ENS telephones were inoperable. This was related to |
| the offsite damage to a 200-pair telecommunications cable affecting Palo |
| Verde. The initial call was placed from the Nuclear Regulatory Affairs |
| Director's cellular telephone, and that phone number was also provided to |
| the [headquarters operations officer] if followup was necessary prior to |
| restoration of the ENS." |
| |
| "The current prognosis for full restoration of the ENS is approximately 2400 |
| MST. If the Palo Verde Units 1, 2, or 3 cannot be reached via the ENS, |
| [commercial] ... phone numbers are available. [Call the NRC operations |
| officer for site contact numbers.] ..." |
| |
| "Emergency Plan notification system backups for communication with State and |
| County agencies were confirmed to remain operable; therefore, this |
| notification was only for the loss of ENS and did not reflect a loss of |
| emergency assessment or notification capability." |
| |
| "There is no corresponding 10 CFR 50.73 reporting requirement. Palo Verde |
| does not expect to followup this report with a Licensee Event Report |
| (LER)." |
| |
| "Palo Verde [plans to] complete a followup notification when full capability |
| is restored." |
| |
| The licensee notified the NRC resident inspector. The NRC operations |
| officer notified the R4DO (Smith). |
| |

| |
| The ENS phones have been restored to complete functionality at 2206MST. The |

| DISCOVERY THAT UNIT SPECIFIC LOADS WERE ON COMMON BUSES |
| |
| The following text is a portion of a facsimile received from the licensee: |
| |
| "FSAR section 1A(B) for compliance to Reg Guide 1.81 states that [the |
| Comanche Peak] design complies with the provisions of Revision 1 of this Reg |
| Guide. Contrary to the above, unit specific [118-volt AC] loads fed from |
| common buses XEC1-1 and XEC2-1 were shared between two units." |
| |
| The licensee stated that affected loads involve a lot of different equipment |
| and systems but did not specify which equipment or systems. The licensee |
| also stated that the units are not currently in any technical specification |
| limiting conditions for operation as a result of this issue because the |
| loads are now aligned to an alternate power supply. Corrective actions have |
| not yet been determined. |
| |
| The licensee notified the NRC resident inspector. |

| FAILURE OF HIGH PRESSURE FIRE WATER SPRINKLER SYSTEMS TO MEET SYSTEM |
| OPERABILITY REQUIREMENTS (24-Hour Report) - (Refer the event #36018 for a |
| similar event at Portsmouth and refer to event #35790 and event #36552 for |
| related events at Paducah.) |
| |
| The following text is a portion of a facsimile received from Portsmouth: |
| |
| "On 01/19/00 at approximately 0900 hours during the scheduled semi-annual |
| walkdown of the X-330 Process Building high pressure fire water (HPFW) |
| systems, the Plant Shift Superintendent (PSS) was notified that sprinkler |
| systems #284 and #365 were not capable of meeting system operability |
| requirements due to corrosion problems identified on adjacent sprinkler |
| heads." |
| |
| "Two adjacent heads on system #284 and three adjacent heads on system #365 |
| were identified with corrosion around the valve seat. This condition |
| prevents the heads from being able to actuate at normal water pressure. |
| When two adjacent heads are inoperable, the system is considered unable to |
| perform its design function. The PSS declared the affected sprinkler |
| systems inoperable, and [technical safety requirement (TSR)] required |
| actions were initiated and completed." |
| |
| "Further inspections of the Process Building sprinkler systems are planned. |
| This report will be updated if additional sprinkler systems are determined |
| to be inoperable." |
| |
| "There was no loss of hazardous/radioactive material or |
| radioactive/radiological contamination exposure as a result of this event." |
| |
| At the time of this event notification, Portsmouth personnel had completed |
| repairs and were in the process of closing out the paperwork to be able to |
| declare the systems operable again. |
| |
| Portsmouth personnel notified the NRC resident inspector and a Department of |
| Energy site representative. |
| |
| (Call the NRC operations officer for a site contact telephone number.) |

| DISCOVERY OF A LOOSE STEM NUT AND THE INABILITY TO MANUALLY OPERATE A SAFE |
| SHUTDOWN MAKEUP PUMP (SSMP) INJECTION VALVE FOLLOWED BY DISCOVERY THAT THE |
| VALVE WAS NOT FULLY CLOSED |
| |
| The following text is a portion of a facsimile received from the licensee: |
| |
| "On January 19, 2000, at 1357 [CST], the MO 2-2901-8 [valve] (SSMP injection |
| to Unit 2) was taken [out of service] for planned maintenance on the valve |
| position limit switches. At 1455 [CST], the Maintenance Supervisor notified |
| the control room that the stem nut was found loose and [that] the valve |
| could not be manually operated. For Unit 2, a 14-day technical |
| specification [(TS) limiting condition for operation (LCO)] was entered per |
| TS 3.8.J, and a 14-day LCO for administrative technical requirements (ATR) |
| was entered. At 1605 [CST,] it was determined that the valve was not fully |
| closed, and the SSMP system [was] declared inoperable to Unit 1. [As a |
| result, a] 14-day LCO for [TSs] and a 14-day ATR [were] entered for Unit 1. |
| A plan is being developed to repair/correct the MO 2-2901-8 [valve]." |
| |
| "It was determined at 2040 [CST] that this event is reportable ... ." |
| |
| The licensee stated that both the pump and the valve have quarterly |
| surveillances and that the surveillances were up to date. |
| |
| The licensee plans to notify the NRC resident inspector. |
