| 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.                       |
|                                                                              |

| "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."                                                     |

| 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.                                                  |
|                                                                              |

| 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.                                                      |
|                                                                              |
