| MISSING TRITIUM FILLED EXIT SIGNS |
| |
| The licensee contacted the NRC Operations Center to report the loss of three |
| tritium-filled exit signs, each containing 11.5 Ci, from a dormitory. The |
| signs had initially been found to have been removed late in 1999, and the |
| licensee had contacted the Region III office (G. Wright) at that time. |
| During the semester break, housing personnel searched all student rooms but |
| were unable to locate the signs. All other tritium filled signs have been |
| removed from the dormitory and returned to the vendor. |

| 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 text is a portion of a facsimile received from 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 |

| INADVERTENT SAFETY INJECTION DUE TO ELECTRICAL FAULT AND REACTOR TRIP |
| |
| Technicians were performing a modification to the vital inverter 2-IV when a |
| safety injection signal was generated due to an electrical problem on vital |
| instrument bus 2-IV. When the technicians were lifting a lead on the sync |
| signal input to the inverter 2-IV in accordance with the modification, an |
| inadvertent safety injection signal was generated. When the safety |
| injection actuated, only Train 'A' safety injection occurred. The cause of |
| the reactor trip is unknown at this time though it is expected with a safety |
| injection. The operators followed the emergency procedures and started the |
| Train 'B' safety injection and residual heat removal pumps; the train 'B' |
| centrifugal charging pump started automatically (reason unknown and being |
| investigated). The 2A-A motor-driven auxiliary feedwater pump tripped for |
| unknown reasons. The #2 steam generator atmospheric relief valve controller |
| appears to have failed, which required operators to take manual control and |
| close the relief valve. An event investigation has been initiated, and all |
| problems will be answered before the unit is restarted. |
| |
| The plant is currently stable in Mode 3 with heat removal via the |
| atmospheric reliefs and feedwater via the 2B-B motor-driven and |
| turbine-driven auxiliary feedwater pumps. All rods fully inserted. The |
| safety injection signal was from the 'Low Steam Generator Pressure' section, |
| and the main steam isolation valves closed automatically. The plant has no |
| steam generator tube leaks. |
| |
| The licensee notified the NRC Resident Inspector. |

| AGREEMENT STATE REPORT INVOLVING TROXLER DENSITY GAUGE MISSING FROM NUCLEAR |
| TESTING SERVICES LOCATED IN SALT LAKE CITY, UTAH |
| |
| At 1000 MST on 01/18/00, Nuclear Testing Services located in Salt Lake City |
| notified the Utah Division of Radiation Control of a lost, missing, or |
| stolen gauge (Utah Incident Report UT-00-0002). The missing gauge was a |
| Troxler Electronic Laboratories, Inc. gauge (model number 3430, gauge |
| serial number 20882). The gauge contained two sealed sources: cesium-137 ( |
| source serial number 7-2293) and americium-241/beryllium (source serial |
| number 47-16381). Apparently, the licensee last had possession of the gauge |
| during April of 1999. This was also when the last leak test was performed. |
| The licensee believes that the gauge may have been leased out to another |
| company during August of 1999. However, there may have been problems with |
| the paperwork or accountability, and there were also changes in personnel. |
| |
| The Utah Division of Radiation Control instructed the licensee to contact |
| local Police Department because there is the possibility of theft. It was |
| also reported that the licensee had been in touch with Troxler. |
| |
| The Utah Division of Radiation Control stated that this event seemed to fit |
| the Abnormal Occurrence Criteria under any substantial breakdown of physical |
| security or material control. It was stated that one of those deals with |
| accountability systems. |
| |
| (Call the NRC operations center for a state contact telephone number.) |
