| AGREEMENT STATE REPORT - STOLEN TROXLER MOISTURE DENSITY GAUGE               |
|                                                                              |
| "The gauge was in use on February 18, 2003. At close of business, the        |
| operator locked the gauge handle, placed it in its transportation case, and  |
| locked the case with chain and lock to a projection inside a Conex           |
| container. The Conex was then padlocked closed for the evening. When the     |
| operator arrived on-site the following morning, (February 19, 2003), he      |
| discovered that all contractor Conexes had been broken into and basically    |
| all Conexes on the site had been 'cleaned out.' The Houston Police           |
| Department was notified, arrived on site, and took statements from all       |
| personnel suffering a loss. The stolen gauge was a Troxler Model 3430,       |
| Serial No.: 20385, containing two sources: a 1.48GBq/40 milicuries (+/- 10%) |
| Am-241:Be source, Serial No.: 47-15863, and a 0.30 GBq/8 millicuries (+/-    |
| 10%) Cs-137 source, Serial No.: 75-1733. The site is believed to be located  |
| in Harris County. The gauge and sources were last leak tested on August 5.   |
| 2002, with negative leakage results."                                        |

| LIMIT FOR 2002                                                               |

| During QA audit of licensee by Oregon Department of Human Services,          |
| Radiation Protection Services, it was determined that one radiographer       |
| employed by the licensee had exceeded his 2002 annual dose limit by          |
| approximately 800 millirem.  This discrepancy was evident by the difference  |
| between pocket ion dosimeter and TLD readings.  Oregon Radiation Protection  |
| Services continues to investigate.                                           |

| CALIFORNIA AGREEMENT STATE REPORT FOR MEDICAL EVENT AT UNIVERSITY OF         |
| CALIFORNIA                                                                   |
|                                                                              |
| "I took a call on a therapeutic misadministration from the RSO for UCIMC (LN |
| 0278-30). The incident involved the administration (via injection) of Y-90   |
| microspheres (25 microns) for the treatment of unresectable hepatic          |
| carcinoma. The intended dosage was 96.2 millicuries, and the administered    |
| dosage was approximately 38.48 millicuries (i.e., an underdose of 60%).      |
|                                                                              |
| "The delivery system consists of an injection system, connected to the vial  |
| containing the microspheres, which has one line leading to a receiving vial, |
| and another to the patient. The direction of the flow is determined by       |
| position of the valve connecting these two lines. Just beyond the vial       |
| containing the microspheres there are also two mounted detectors (like small |
| pocket chambers), which give a visual indication when the microspheres begin |
| moving out of the vial.                                                      |
|                                                                              |
| "The physicist was priming the system prior to a scheduled treatment. When   |
| the priming reaches the point that the microspheres begin to exit the vial,  |
| the valve is turned to direct the flow from the "receiving vial" to the      |
| patient. In this case, the physicist accidentally over-primed the system and |
| about 60% of the activity washed in the receiving vial. The physician, an    |
| authorized user, was also present during the treatment. They completed this  |
| treatment, and the physician is still reviewing whether it is necessary to   |
| perform another treatment to reach the prescribed dosage, or whether this    |
| treatment will be adequate as it stands.                                     |
|                                                                              |
| "The licensee is awaiting a report from the physician and physicist as to    |
| what might have caused this to occur. At the present time, they think it may |
| simply be that the physicist did not respond quickly enough to the           |
| indication on the detectors that activity was passing out of the isotope     |
| vial. That is, it may simply be a slow reflex problem. The manufacturer      |
| happened to be on site at the time of the incident, and indicated there had  |
| been two similar previous events (one allegedly at a hospital in PA), but no |
| further details on the events were obtained by the licensee."                |

| On 2/21/03 at approximately 1030 EST, the radio-pharmacy in the Nuclear      |
| Medicine Department of the Fairfax Hospital received a shipment of radio     |
| pharmaceuticals.  As they were preparing to administer a dose to a patient,  |
| they discovered that one syringe containing 10 millicuries of                |
| Technetium-99M Mag-3 was missing.   The licensee stated that the dose was    |
| listed on the in-processing documents as received.  The licensee's current   |

| UNUSUAL EVENT DUE TO MAIN STEAM LINE ISOLATION WITH SAFETY INJECTION         |
|                                                                              |
| The following information was received from the licensee via facsimile:      |
|                                                                              |
| "At 1548 [EST], on 2/24/03, Beaver Valley Unit 1 experienced an automatic    |
| reactor trip and safety injection on low steam line pressure.  An automatic  |
| main steam line isolation also occurred and all three main steam line        |
| isolation valves shut.  After the automatic actions occurred, operators      |
| noted that all three steam generator pressures appeared normal. Operators    |
| were dispatched to investigate in the field and found no indications of a    |
| steam leak.                                                                  |
|                                                                              |
| "Emergency procedure E-0, Response to Reactor Trip and Safety Injection, was |
| entered at 1548.  At 1600, the Shift Manager declared an unusual event.      |
| Initial notifications to state and local agencies were complete at 1609.     |
| Per procedure E-0, after meeting Safety Injection termination criteria, the  |
| Boron Injection Tank was isolated at 1603 and Safety Injection was           |
| terminated.                                                                  |
|                                                                              |
| "Initial review of computer information revealed that closure of the 'C'     |
| main steam isolation valve is the probable cause of the reactor trip, safety |
| injection and main steam isolation.                                          |
|                                                                              |
| "The gaseous release occurred due to tritium in the secondary and the fact   |
| that the turbine driven auxiliary feed pump is in service. No protective     |
| action recommendations were made.                                            |
|                                                                              |

| Technical Support Center is staffed but not activated.  All control rods     |
| inserted into the core.  The electrical grid is stable.  Unit 1 is stable.   |
| Core cooling is being accomplished via auxiliary feedwater and steam         |
| generator atmospheric dump valves.  There is previously identified steam     |
| generator "B" tube leakage of less than 0.1 gallons per day.                 |

| "At 1735 [2/24/03], the Unusual Event was terminated.  This was based upon   |
| termination of the safety injection, completion of emergency operating       |
| procedure actions, and stabilization of plant conditions.  This was          |
| previously communicated to the NRC Operations Center at 1740.                |
|                                                                              |
| "As of 0245, on 2/25/03, Unit 1 remains in mode 3.  Heat removal Is via the  |
| steam generator atmospheric steam release valves.  All main steam isolation  |
| valves remain shut as the event investigation continues.  The preliminary    |
| initiator of the event remains the inadvertent closure of "C" Main Steam     |
| Isolation Valve.  The offsite release (due to tritium activity in the        |
| secondary) has been calculated and determined to be of minimal/no effect on  |
| the public.  The projected whole body dose was 5.12E-7 mrem [millirem].      |
| This is equivalent to 3.41 E-6 percent of the yearly Offsite Dose            |
| Calculation Manual Limit."                                                   |
