| AGREEMENT STATE REPORT INVOLVING THE DISCOVERY OF A CPN MOISTURE
DENSITY     |
| GAUGE BY A THIEL GEOTECH CLIENT IN OMAHA, NEBRASKA, AND THE SUBSEQUENT  
    |
| REPORT OF THE LOSS OF THE SAME GAUGE BY GEOTECHNICAL SERVICES, INC.         
|
|                                                                              |
| At approximately 1100 CDT on 07/23/02, an engineering company (Thiel         |
| Geotech) notified the Nebraska Division of Radioactive Materials that one of |
| their clients had found a CPN moisture density gauge.  The gauge was         |
| discovered in a pad-locked transport container at a construction site        |
| (approximately 180th and Harrison) in Omaha, Nebraska.  Thiel Geotech is     |
| licensed to use/hold similar gauges, and representatives of Thiel Geotech    |
| transported the gauge to their office in order to secure it.                 |
|                                                                              |
| The State reported that the gauge (model CPN-131, serial number MD00105439)  |
| contained a maximum of 50 millicuries of americium-241/beryllium and a       |
| maximum of 10 millicuries of cesium-137.  At the request of the State, Thiel |
| Geotech broke through the padlock to check the gauge and to perform surveys. |
| There was no observable damage, and the survey results were normal.  The     |
| State was able to identify the owner of the gauge fairly soon via an         |
| ownership label and the serial number.                                       |
|                                                                              |
| At approximately 1239 CDT on 07/23/02, Geotechnical Services, Inc., notified |
| the Nebraska Division of Radioactive Materials of the loss of the same       |
| gauge.  Geotechnical Services, Inc., also notified local law enforcement.    |
|                                                                              |
| The Nebraska Division of Radioactive Materials has had several conversations |
| with both companies and has also been in contact with local law enforcement. |
| The State requested Thiel Geotech to hold the gauge pending the State's      |
| investigation, which is currently planned for tomorrow.                      |
|                                                                              |
| (Call the NRC operations officer for a Nebraska Division of Radioactive      |
| Materials contact telephone number.)                                         |

| The train 'A' control room area chill water was declared inoperable at 1350  |
| EDT due to a refrigerant leak.  Subsequently the train 'B' control room area |
| chill water tripped and at 1705 EDT technical specification 3.0.3 was        |
| entered due to both trains being inoperable.  At 1747 EDT the train 'A' was  |
| declared operable and the technical specification 3.0.3 was exited.  The     |
| report is made due to the 42 minutes both trains were inoperable which could |
| have prevented the performance of a safety function.  Troubleshooting        |
| continues on train 'B'.                                                      |

| On 7/23/02 a male patient underwent surgery for implantation of Iodine-125   |
| seeds as part of the treatment plan for prostate cancer.  Following the      |
| surgery, the technician discovered that only 7 instead of 8 of the original  |
| 110 seeds delivered to the OR [Operating Room] were remaining.  A survey of  |
| the area was unable to locate the missing seed [338 millicuries].  The RSO   |
| believes that either the missing seed was inadvertently washed down the OR   |
| sink drain during cleanup or that 103 instead of 102 seeds prescribed were   |
| implanted.  The licensee will submit a written report within 30 days.        |

| "At 09:24 p.m. on 7/26/02, the Shift Manager was notified by the Refueling   |
| Floor Manager that a Dry Fuel Storage cask had been accidentally filled with |
| an argon/helium gas mix in lieu of 100% helium gas as required by the        |
| certificate of compliance for Susquehanna's Dry Fuel Cask Storage program.   |
| The affected cask was in the process of being sealed and prepared for        |
| shipment from the Refueling Floor to the Horizontal Storage Module located   |
| on site. Site Engineering and the vendor have been contacted to provide      |
| guidance on the affect of the argon gas on the Storage System. Temperature   |

| The licensee's security personnel discovered a stub end of a hand rolled     |
| cigarette of questionable material in the room above diesel generator 'A.'   |
| It appeared old and had no odor.  Fairfield County Sheriff's Department was  |
| contacted and they dispatched a unit.  They potentially identified the       |
| contents as marijuana and took custody of the cigarette.  They will submit   |
| it to the South Carolina State Law Enforcement Division for analysis.  The   |
| analysis will take about a week or more and followup notification will be    |
| made if needed.  This notification was made due to Fairfield County          |
| involvement and possible media coverage.  There is no impact on plant        |

| "On 7/27/02 at 1227 CDT, Browns Ferry Unit 2 scrammed due to a Main          |
| Generator load reject signal, when the Main Generator breaker opened.  The   |
| breaker trip was caused by a Generator Neutral Overvoltage relay trip.  The  |
| cause of the Generator Neutral Overvoltage is under investigation.  All      |
| systems responded as required to the scram signal, no ECCS initiations       |
| occurred as a result of the scram signal.  As expected, Main Steam Relief    |
| Valves (MSRVs) opened due to the high reactor pressure as a result of the    |
| Main Turbine/Generator trip."                                                |
