| "On June 25, 2003, a nuclear medicine technologist gave a 243 microcurie     |

| iodine-123 capsule to the wrong patient.  There were two patients with the   |

| same last name and middle initial but different first names in the           |

| outpatient waiting room.  The wrong patient responded when the technologist  |

| took the patient into the nuclear medicine department, explained the         |

| procedure, and had him fill out a thyroid questionnaire.  After the patient  |

| swallowed the capsule, he informed the technologist that he was not at the   |

| hospital for a thyroid study.  The patient was informed of the               |

| misadministration.  The licensee did not report whether the referring        |

| physician was informed.                                                      |

| "Cause: The technologist failed to fully identify the patient.               |

|                                                                              |

| "Corrective Action: The technologist was counseled. To prevent a recurrence, |

| the technologists will question the patient's full name and match their date |

| of birth in the future.  The technologist will also ask the patient what     |

| examination or procedure they are scheduled for before initiating any        |

| test."                                                                       |

| SCRAP ZIRCONIUM RODS SHIPPED TO RECYCLER IN CANADA CONTAINING U-235 FUEL     |

| PELLETS                                                                      |

| Between 3-4 weeks ago Westinghouse Hematite shipped approximately 18,000     |

| scrap zirconium rods to Mississauga Metals and Alloys, Inc. in Brampton,     |

| Ontario, Canada for recycling.  Scrap zirconium rods require a 100% visual   |

| inspection prior to shipment offsite to ensure that they do not contain any  |

| fuel pellets.  Last Thursday on 7/24/03, the recycler discovered thirty-six  |

| (36) U-235 pellets (4.2 w/o) after processing about 25% of the scrap rods.   |

| The individual at Mississauga responsible for contacting Westinghouse did    |

| not return to work until Monday and, thus, Westinghouse was not informed     |

| until 0730 CDT on 7/28/03.  The pellets contain a total of six (6) grams     |

| U-235.  Westinghouse is dispatching staff to the recycling facility to       |

| assist in determining appropriate corrective actions.                        |

| RPS ACTUATION, SPECIFIED SYSTEM ACTUATION                                    |

|                                                                              |

| "On July 28, 2003, at approximately 18:54 Mountain Standard Time (MST) Palo  |

| Verde Unit 3 experienced an automatic reactor trip on low DNBR [Departure    |

| from Nucleate Boiling Ratio] from approximately 98% rated thermal power due  |

| to reduced reactor coolant system flow when the main turbine tripped during  |

| a grid perturbation. Unit 3 was at normal temperature and pressure prior to  |

| the trip. All CEAs inserted fully into the reactor core. This was an         |

| uncomplicated reactor trip. No emergency classification was required per the |

| Emergency Plan. No automatic ESF actuations occurred and none were required. |

| The operators initiated a manual Main Steam Isolation System (MSIS)          |

| actuation, in accordance with the emergency operations procedures in         |

| response to the loss of forced reactor coolant system flow. Safety related   |

| buses remained energized during and following the reactor trip. The          |

| Emergency Diesel Generators did not start and were not required. The offsite |

| power grid is stable. No significant LCOs have been entered as a result of   |

| this event. No major equipment was inoperable prior to the event that        |

| contributed to the event.                                                    |

|                                                                              |

| "Unit 3 is stabilizing at approximately 520 degrees F and 2150 psia pressure |

| in Mode 3. The reactor coolant system remains in natural circulation with    |

| heat removal via the atmospheric dump valves and feedwater from the          |

| essential auxiliary feedwater system. The event did not result in any        |

| challenges to fission product barriers and there were no adverse safety      |

| consequences as a result of this event. The event did not adversely affect   |

| the safe operation of the plant or the health and safety of the public.      |

|                                                                              |

| "Palo Verde Units 1 and 2 also observed the grid perturbation, but are       |

| continuing to operate in Mode 1 at approximately 98% rated thermal power.    |

| The cause of the perturbation is believed to be associated with switching in |

| a nearby Hassayampa yard by Salt River Project. A fossil power plant in the  |

| vicinity also tripped off line during the grid perturbation event.           |

|                                                                              |

| "The [NRC] Senior Resident Inspector was informed of the Unit 3 reactor trip |

| and this notification. The Senior Resident Inspector has arrived on-site to  |

| observe response to the reactor trip."                                       |

| "This is a follow-up notification to the automatic reactor trip event        |

| reported on July 28, 2003 (ENS # 40029) for Palo Verde Unit 3. The plant     |

| remains stable in Mode 3 at approximately 585 degrees and 2250 psia. Reactor |

| coolant system (RCS) forced circulation has been restored with two reactor   |

| coolant pumps (RCP) in operation.  Heat removal remains via the atmospheric  |

| dump valves and the non-essential auxiliary feedwater pump is supplying      |

| UNIT 2 WAS MANUALLY TRIPPED AFTER  A STUCK OPEN SPRAY VALVE FAILED TO CLOSE  |

|                                                                              |

| "On July 29, 2003, at approximately 1518 Mountain Standard Time (MST) Palo   |

| Verde Unit 2 plant operators manually tripped the reactor from approximately |

| 98% rated thermal power due to reduced reactor coolant system pressure when  |

| a pressurizer spray valve opened and failed to close on operator demand.     |

| Unit 2 was at normal temperature and pressure prior to the trip. All CEAs    |

| inserted fully into the reactor core. This was an uncomplicated reactor      |

| trip. No emergency classification was required per the Emergency Plan.       |

| Containment Isolation and Safety Injection Actuation Signals were received   |

| following the manual reactor trip per design. Safety related buses remained  |

| energized during and following the reactor trip. No significant LCOs have    |

| been entered as a result of this event. The pressurizer spray valve that     |

| initiated the event was being placed in service following maintenance.       |

|                                                                              |

| "Unit 2 is stabilized in Mode 3 at approximately 564 degrees F and 2200      |

| psia. The reactor coolant system remains in natural circulation with heat    |

| removal via Steam Bypass Control to the main condenser. The event did not    |

| result in any challenges to fission product barriers and there were no       |

| adverse safety consequences as a result of this event. The event did not     |

| adversely affect the safe operation of the plant or the health and safety of |

| the public.                                                                  |

|                                                                              |

| "The Resident Inspector was informed of the Unit 2 reactor trip and this     |

| notification. The Resident Inspector is onsite to observe response to the    |

| reactor trip.                                                                |

|                                                                              |

| "The reactor coolant pumps were secured after the trip to stop continued     |

| spray flow and depressurization per the alarm response procedure.  The       |

| offsite electrical power grid is stable."                                    |
