| On September 27, 2002 at approximately 15:00 Mountain Standard Time, Palo    |

| Verde Nuclear Generating Station                                             |

| (PVNGS) notified the Environmental Protection Agency (EPA) that a INITIAL    |

| NOTIFICATION OF CONTINUOUS RELEASE was being reported.                       |

|                                                                              |

| The following information was provided to the National Response Center and   |

| State of Arizona:                                                            |

| "Palo Verde Nuclear Generating Station is calling to make an initial         |

| notification of a continuous release in accordance                           |

| with CERCLA Section 103(f)(2). 40CFR 302.8 (d).  This is not an accidental   |

| or episodic release.                                                         |

| Palo Verde Nuclear Generating Station will be performing a scheduled steam   |

| generator cleaning activity as part of its routine refueling outage for Unit |

| 1.  The steam generator cleaning activity will begin on Saturday, September  |

| 28 at approximately 18:00. During this activity, Palo Verde Nuclear          |

| Generating Station will exceed the Reportable Quantities for the release of  |

| ammonia and hydrazine.  The same activity is scheduled to occur during the   |

| Unit 3 refueling outage, spring of 2003.  The activity occurs approximately  |

| once per every five to seven years on each unit.  The hazardous substances   |

| released are ammonia (CAS #7684-41-7) and hydrazine (CAS #302-01-2).  PVNGS  |

| expects no adverse effects to health and welfare of the general public, nor  |

| to the environment.                                                          |

| continuous release in accordance with CERCLA [Comprehensive Environmental    |

| Response, Compensation, and Liability Act] Section 103(f)(2), 40 CFR         |

| 302.8(d). This was not an accidental or episodic release. The planned        |

| release was the result of steam generator cleaning activities and would      |

| result in exceeding the Reportable Quantities for the release of ammonia     |

| (CAS #7664-41-7) and hydrazine (CAS #302-01-2).                              |

| Arizona will identify the lower levels.                                      |

| ATTEMPTED THEFT OF A TROXLER GAUGE                                           |

|                                                                              |

| The Texas Department of Health reported the attempted theft of a Troxler     |

| Model 3430, (serial # unknown), on the night of 3/31/03 from a secure        |

| storage trailer at a Texas Department of Transportation construction site in |

| Abilene, TX.  Site personnel discovered the gauge in an open case on the     |

| floor of a construction trailer with its lock cut.  The trailer and its      |

| storage closet had been broken into.  The sealed source contains 8           |

| millicuries of Cs-137 and 40 millicuries of Am-241/Be.  Gauge is currently   |

| secured in a different area awaiting results of leak and serviceability      |

| tests.  An investigation is in process to determine whether other items were |

| stolen, or whether this gauge was the only target of the attempted theft.    |

|                                                                              |

| This event is technically not reportable, but was entered as an attempted    |

| theft due to three other similar incidents that did result in stolen gauges  |

| in the Dallas-Fort Worth area under similar circumstances.  The Texas        |

| Department of Transportation notified all other licensee's possessing        |

| portable nuclear gauges in the Abiline and Dallas-Fort Worth regions, along  |

| with local police and the Dallas FBI office.                                 |

| At 2201, a fire started in the pressurizer doghouse.  Welding operations     |

| were ongoing in the upper part of the space, and a slag catchment device     |

| lower in the space caught fire.  The fire brigade responded to the scene.    |

| At 2219, the licensee declared an Unusual Event because of an ongoing fire   |

| in the vital area for greater than 15 minutes.  At 2234, the fire was put    |

| out by pouring water down onto the fire from above, and a reflash watch was  |

| set.  There was no damage noted to plant equipment, and no injuries to       |

| personnel.                                                                   |

| At 2300, the licensee secured from the Unusual Event.  There was no damage   |

| noted to plant components, and scaffolding will be erected to conduct        |

| further inspections.                                                         |

| The cause of the fire was slag from welding operations that fell through     |

| some fire blankets and ignited the herculite underneath.  A fire brigade     |

| member will be sent back into the space this morning to conduct further      |

| damage assessment.                                                           |

|  AUXILIARY FEEDWATER ACTUATION DUE TO LOW STEAM GENERATOR WATER LEVEL        |

|                                                                              |

| The following information was received from the Licensee via facsimile:      |

|                                                                              |

| "On April 8, 2003 with Unit 2 in Mode 5 (Cold Shutdown), the auxiliary       |

| feedwater (AFW) system automatically actuated on a valid signal when the     |

| solid state protection system (SSPS) was placed in service while the steam   |

| generator level was below the AFW actuation set point. The actuation was     |

| unplanned.                                                                   |

| "S/G [Steam Generator] 2-1 level had been lowered to below the feed ring for |

| work on an AFW system check valve. Operations was performing testing on the  |

| AFW system using AFW Pump 2-2, and was going to restore S/G level to normal  |

| (approximately 33% narrow range level) during the test. In conjunction with  |

| the AFW system testing, SSPS was being placed in service in preparation for  |

| an expected Mode 4 transition later in the watch after the AFW system        |

| testing was complete. When SSPS was placed in service, the low level in S/G  |

| 2-1 made up the coincidence for starting the motor driven AFW pumps. AFW     |

| Pump 2-2 was in operation, but AFW Pump 2-3 started in response to the low   |

| S/G level. AFW Pump 2-3 was aligned for recirculation flow, and did not feed |

| forward on the automatic start. Operations then restored S/G 2-1 level above |

| the low level trip point and secured AFW Pump 2-3.                           |

|                                                                              |

| "The start of AFW Pump 2-3 on a valid low level signal from S/G 2-1 is       |

| reportable as an 8  [hr.] non-emergency                                      |

| report."                                                                     |

| In addition to the AFW actuation, the Licensees did receive a S/G blowdown   |

| isolation signal but S/G blowdown was not in service at the time.            |

|                                                                              |

| The Licensee has informed the NRC Resident Inspector.                        |
