| ALLOY IDENTIFICATION INSTRUMENT LOST DURING SHIPMENT                         |
|                                                                              |
| On March 14, 1999, DC Fabricators shipped a small alloy identification       |
| instrument to Texas Nuclear Technology via UPS.  In early August, DC         |
| Fabricators determined that the instrument had not arrived at Texas Nuclear  |
| Technology.  The device contains 45 millicuries of Fe-55 and 4 millicuries   |
| of Cd-109.  UPS is looking for the device but has been unable to locate it   |
| to date.                                                                     |
|                                                                              |

|                                                                              |
| The package has been located. It was delivered by UPS to the Texas Nuclear   |
| facility, but the driver left it at the main entrance, not the receiving     |
| department. The receptionist at the main entrance was a new hire and did not |
| know to send the package to the receiving department. The package was        |
| subsequently misplaced temporarily. The licensee has contacted the NRC       |
| Region I office regarding this update. Notified R1DO (Hinson).               |

| NORMAL POWER SUPPLY TO EMERGENCY  ELECTRICAL BUS LOST DUE TO PERSONNEL       |
| ERROR                                                                        |
|                                                                              |
| Emergency bus E2 was temporarily deenergized after a plant worker bumped 4kV |
| breaker 5215, the normal supply breaker to the bus, causing it to trip. The  |
| B emergency diesel generator (EDG) automatically started due to an           |
| undervoltage condition on bus E2, and loaded to the bus, restoring power.    |
| The licensee reported that the operating residual heat removal (RHR) pump    |
| stopped running due to the loss of power to bus E2, but operators manually   |
| started the standby pump and restored shutdown cooling within two minutes.   |
| Reactor coolant system temperature did not increase appreciably during the   |
| alignment of the standby RHR pump.                                           |
|                                                                              |
| The EDG continues to supply power to bus E2 while the licensee makes         |
| preparations to transfer back to the normal power supply. The NRC resident   |
| inspector has been informed of this event by the licensee.                   |
