| 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.) |

| BOTH TRAINS OF CONTROL ROOM AREA CHILL WATER INOPERABLE |
| |
| 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'. |
| |
| The licensee notified the NRC Resident Inspector. |
| |
| * * * RETRACTED AT 1305 EDT ON 7/26/02 BY JIM DEAN TO FANGIE JONES * * * |
| |
| The licensee is retracting the event based on further determination that the |
| 'A' train of the control room area chill water system remained operable and |
| capable of performing its safety related function in the presence of the |
| refrigerant leak. |
| |
| The licensee notified the NRC Resident Inspector. The R2DO (Mark Lesser) |
| was notified. |

| I-125 SEED UNACCOUNTED FOR FOLLOWING IMPLANTATION |
| |
| 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. |

| DRY FUEL STORAGE CASK FILLED WITH WRONG GAS |
| |
| "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 |
| monitoring is in progress to detect any changes in the loaded canister until |
| a final determination can be made. Because of the reduction in the thermal |
| conductivity of the argon/helium mixture, this defect is believed to |
| represent a potential significant reduction in the effectiveness of the |
| spent fuel confinement system and is reportable under 10 CFR 72.75(b)(2) and |
| 10 CFR 72.75(b)(3)." |
| |
| The NRC Resident Inspector has been notified. |

| INFORMATION CALL THAT INVOLVES LOCAL AUTHORITIES AND POSSIBLE MEDIA
|
| ATTENTION |
| |
| 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 |
| operation. |
| |
| The licensee notified the NRC Resident Inspector. |

| AUTOMATIC REACTOR SCRAM ON MAIN GENERATOR LOAD REJECT |
| |
| "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." |
| |
| The licensee is investigating the cause of the trip and will remain in Hot |
| Shutdown until everything is known prior to plant startup. |
| |
| The licensee informed the NRC Resident Inspector. |
